1.Scope
1.1Purpose—The purpose of this SAE Information Report is to specify the requirements necessary to fully define
the Serial Data Communication Interface (SCI) used in the reprogramming of emission-related powertrain Electronic Control Units (ECU) in DaimlerChrysler Corporation (Chrysler Group) vehicles. It is intended to satisfy new regulations proposed by the federal U.S. Environmental Protection Agency (EPA) and California Air Resource Board (CARB) regulatory agencies regarding “pass-thru programming” of all On-Board Diagnostic (OBD) compliant emission-related powertrain devices. These requirements are necessary to provide independent automotive service organizations and after-market scan tool suppliers the ability to reprogram emission-related powertrain ECUs for all manufacturers of automotive vehicles.
Specifically, this document details the SCI physical layer and SCI data link layer requirements necessary to establish communications between a diagnostic tester and an ECU. It further specifies additional requirements for the application of a flash strobe voltage multiplexed on the SCI communication link for purposes of ECU reprogramming. This document does not specify the content or meaning of the application messages or diagnostic protocol to be transmitted on the SCI communication link. It only defines a generic method to transfer data between a diagnostic tester and an ECU, regardless of application messaging structure.
This specification will be referenced from within SAE J2534 Pass-Thru Programming as a technical information report. In this regard, the inclusion of the SCI communication link is in addition to the approved OBD communication links previously specified in SAE J2534, and constitutes unique DaimlerChrysler Corporation (Chrysler Group) manufacturer-specific requirements.
1.2Applications—This document shall strictly apply to DaimlerChrysler Corporation vehicles developed and
manufactured exclusively by the former Chrysler Corporation, and for purposes of clarification, referred to herein as DaimlerChrysler Corporation (Chrysler Group). This document shall not apply to other DaimlerChrysler Corporation vehicles or subsidiaries, including products developed and manufactured by Mercedes-Benz, Smart, or Mitsubishi Motors Corporation. The SCI communication link defined herein shall apply to OBD vehicles retroactive to the 1994 model year.
1.3History—DaimlerChrysler Corporation (Chrysler Group) introduced flash technology into emission-related
powertrain ECUs beginning in the 1993 model year. Flash technology consisted of implementing reprogrammable memory devices into powertrain ECUs for purposes of updating software functionality and calibrations in the customer field (service environment), assembly plant (manufacturing environment), and vehicle development (engineering environment). Reprogramming events in the field require strict compliance to corporate guidelines based on the following criteria:
Vehicle performance / driveability
Vehicle safety
Vehicle emissions
Vehicle fuel economy
Customer satisfaction
The DaimlerChrysler Corporation (Chrysler Group) corporate flash strategy consists of incorporating proprietary standards and requirements into the flash process. These requirements involve the integration of multiple levels of protective security measures using software and hardware lockout techniques including additional safeguard mechanisms controlled via internal corporate processes and corporate test tools. New regulations will force a change in the current DaimlerChrysler Corporation (Chrysler Group) flash strategy and process.

5.Technical Overview
5.1General—The Serial Data Communication Interface (SCI) is defined as a full-duplex, asynchronous, UART-
based serial interface for point-to-point communications between an off-board diagnostic tester and an on-board electronic control unit (ECU). The SCI communication link is required to support the diagnosis and reprogramming of emission-related powertrain devices for DaimlerChrysler Corporation (Chrysler Group) vehicles. It is implemented as a non-inverted 0 to 5 V DC asynchronous system requiring a 5 V DC idle high mode. SCI baud rates are software selectable for data transmission modes. SCI terminations at the diagnostic connector must be software selectable for multiplexing old and new SCI configurations. Additionally, the application of a flash strobe voltage multiplexed on the SCI communication link is required for reprogramming ECU memory devices.
The following points summarize the SCI communication link requirements:
a.Full-duplex, dual-wire interface using one Rx line and one Tx line
b.Non-inverted Transistor-Transistor Logic (TTL) voltage level operation using idle “high” mode
c.Non-Return-To-Zero (NRZ) bit-coding format using 10-bit data frame
d.Multiple data rates of 7812.5 bps, 62.5 Kbps, 125.0 Kbps
e.Flash strobe voltage (Vpp) using multiplexed 20 V DC source
5.2Communication Model—The SCI communication model characterizes the SCI communication behavior into
three conceptual layers: SCI Physical Layer, SCI Data Link Layer, and Message Application Layer. In this regard, SCI communications is accomplished through the conceptual layering of peer entities. Each peer entity forms a virtual communication link. The layers allow transmitted data bits to be grouped into data frames, data frames constructed into messages, and messages mapped into application-specific protocol functions.
This is illustrated in the SCI communication model in Figure 1:
FIGURE 1—SCI COMMUNICATION MODEL DEPICTING THE THREE CONCEPTUAL LAYERS
Note that the SCI communication model does not specify the content or meaning of the application messages or diagnostic protocol to be transmitted on this interface. It only defines a generic method to transfer data between a diagnostic tester and an ECU, regardless of application messaging structure.
6.Physical Layer—The SCI Physical Layer is responsible for transferring data bits between the diagnostic tester
and the ECU. The SCI Physical Layer defines the data transmission rates, electrical signals, physical media, routing, and connectivity to the vehicle.
6.1Data Rate Specification—The SCI communication link shall have a default data rate of 7812.5 bps. A
communication session between a diagnostic tester and an ECU shall always be initiated at the default data rate. A change in data rate can be negotiated once communications are established between the diagnostic tester and ECU. The ECU shall automatically track to the requested data rate following a command sequence from the diagnostic tester. The command sequence is initiated by transmitting a specific training character to the ECU. The ECU shall respond with an acknowledgement character following establishment of the proper data rate. For proper operation of serial communications, the diagnostic tester and ECU shall support the data rates as specified in Figure 2.
FIGURE 2—SCI COMMUNICATION MODES WITH AVAILABLE DATA RATES AND BIT TIMES The bit time is the time required to serially transmit/receive one bit of data. It is equal to one cycle of the baud frequency as determined by the selected data rate.
6.1.1I NITIALIZATION—An ECU shall always initialize to the default low-speed communication rate of 7812.5 bps
following an ECU power-on or reset condition.
6.1.2C OMMUNICATIO N M ODES—An ECU shall support the following communication modes of operation:
a.Low-Speed Mode—The low-speed mode shall be used for initializing a communication exchange or
diagnostic session between a diagnostic tester and an ECU.
b.High-Speed Mode—The high-speed mode(s) shall be used for establishing a data acquisition session
or flash reprogramming download session between a diagnostic tester and an ECU.
6.2Signal Definition—For proper operation of serial communications, the diagnostic tester and ECU shall
correctly determine each signal value as specified as follows.
6.2.1L O GIC L EVELS—A standard Non-Return-to-Zero (NRZ) bit-coding format shall be required using non-inverted
Transistor-Transistor Logic (TTL) voltage levels. The logic states of each binary element are defined as follows:
a.Logic “1” State: A logic “1” state (high) shall be equivalent to a voltage level greater than 4.0 V (i.e.,
80% of Vdd).
b.Logic “0” State:A logic “0” state (low) shall be equivalent to a voltage level less than 1.0 V (i.e., 20% of
Vdd).
The rise and fall times shall be less than 10% of the bit times specified by the data rate. The rise and fall times shall be defined as the time for the voltage to change from 20% to 80% of Vdd (rise time), and from 80% to 20% of Vdd (fall time). This implies that in the 7812.5 bps low-speed mode, the rise time from 1.0 V to 4.0 V shall be no longer than 12.8 microseconds. In the 62.5 Kbps and 125.0 Kbps high-speed modes, rise and fall times shall be no longer than 1.6 microseconds and 0.8 microseconds, respectively.
6.2.2I DLE C ONDITION—An idle condition shall be defined as 10 (or more) consecutive bit times at a logic “1” state.
Hence, the SCI communication link shall enter a “bus high” state when an idle condition is declared.
6.2.3B REAK C O NDITIO N—A break condition shall be defined as 10 (or more) consecutive bit times at a logic “0”
state (i.e., BRK character). The BRK character is used to terminate bus communications and reset all nodes to a ready-to-receive state. Hence, the SCI communication link shall enter a “bus low” state when a break condition is declared.
6.3Routing and Connectivity—Connectivity from the diagnostic tester to the vehicle shall be provided via the
SAE J1962 Diagnostic Connector. Physical routing from the diagnostic connector to each ECU shall be provided via an SCI receive/transmit communication link in accordance to the specifications as follows.
6.3.1D IAGNOSTIC C ONNECTOR C ONFIG URATIONS—The SAE J1962 Diagnostic Connector is an industry-standard
16-pin common connector configuration defined for use in automotive vehicles. The diagnostic connector provides the physical means by which access to the on-board vehicle communication network is accomplished. The specific assignment and functionality of a fixed set of connector terminals has been defined by SAE for common industry-standard use by all vehicle manufacturers. The remaining undefined connector terminals are allocated for manufacturer-specific use for unique applications.
A revision to the SAE J1962 Diagnostic Connector recommended practice was enacted due to new
regulations allowing provisions for the acceptance of a Controller Area Network (CAN) as a viable alternative On-Board Diagnostic (OBD) communication interface. Consequently, new SAE requirements redefined connector pins 6 and 14, previously designated as manufacturer-specific, as SAE-specific for the development and integration of CAN. DaimlerChrysler Corporation (Chrysler Group) had previously designated pins 6 and 14 as SCI receive lines for the engine ECU and transmission ECU, respectively.
Consequently, DaimlerChrysler Corporation (Chrysler Group) has defined two unique connector configurations for use in vehicle applications. Configuration 'A' shall be referred to as the 'old' configuration, and Configuration 'B' shall be referred to as the 'new' configuration. Each connector configuration is defined in the following sections.
a.Configuration 'A'—Configuration 'A' shall be used in DaimlerChrysler Corporation (Chrysler Group)
vehicles beginning in the 1994 model year through the 2001 model year, and shall gradually be
replaced beginning in the 2002 model year by Configuration 'B'. Physical routing to ECUs shall be
handled by providing a separate SCI receive line to each ECU. The engine ECU shall support an SCI
receive line terminated at pin 6, and the transmission ECU shall support an SCI receive line terminated
at pin 14. Both engine and transmission ECUs shall share a common SCI transmit line terminated at
pin 7 (wire-ORed together). SCI connections to pins 6 and 14 shall not electrically interfere with
ISO15765-4 CAN operation. Likewise, SCI connections to pin 7 shall not electrically interfere with
ISO9141-2 operations. Additionally, if a vehicle supports SAE J1979 legislative diagnostics via the
ISO 9141-2 K-line, the SCI transmit lines shall remain wire-ORed together for engine and transmission
communications as specified in Configuration 'A'.
b.Configuration 'B'—Configuration 'B' shall be used in selective DaimlerChrysler Corporation (Chrysler
Group) vehicles beginning in the 2002 model year, and shall eventually be used on all vehicle
applications exclusively. Physical routing to ECUs shall be handled by providing a separate pair of SCI
receive/transmit lines to each ECU. The engine ECU shall support an SCI receive/transmit pair
terminated at pins 12 and 7, respectively. The transmission ECU shall support an SCI receive/transmit
pair terminated at pins 9 and 15, respectively. In this regard, Configuration 'B' supports the
independent interrogation and flash reprogramming of engine and transmission ECUs via SCI
simultaneously. Additionally, SCI connections to pins 6 and 14 have been vacated to allow the
migration to CAN to proceed without exception. This also permits the co-existence of both SCI and
CAN vehicles using Configuration 'B', and supports full compliance to the SAE J1962 diagnostic
connector requirements per the latest SAE publication.
6.3.2D IAGNOSTIC C ONNECTOR T E RMINATIO NS—The SAE J1962 connector terminal assignments are defined in
Figure 3 for each DaimlerChrysler Corporation (Chrysler Group) vehicle configuration. SCI receive/transmit connections are depicted as gray-shaded assignments (viewed from the ECU perspective). Each configuration is shown compared against the SAE industry-standard reference.
FIGURE 3—TERMINAL ASSIGNMENTS AND FUNCTION FOR
SAE J1962 DIAGNOSTIC CONNECTOR CONFIGURATIONS
The SCI receive/transmit re-mapping from Configuration 'A' to Configuration 'B' is defined as follows:
a.Reroute pin 6 (Configuration 'A') to pin 12 (Configuration 'B') for Engine SCI Rx
b.Reroute pin 14 (Configuration 'A') to pin 9 (Configuration 'B') for Transmission SCI Rx
c.Vacate pin 6 and pin 14 for CAN-C (+) and CAN-C (-), respectively
d.Retain pin 7 (Configuration 'B') for Engine SCI Tx only
e.Separate and reroute pin 7 (Configuration 'A') to pin 15 (Configuration 'B') for Transmission SCI Tx
The routing for each diagnostic connector configuration is depicted graphically in Figures 4 and 5.
FIGURE 4—OLD CONFIGURATION 'A' DEPICTED WITH SINGLE SCI TX LINE SHARED PER PAIR OF EMISSION ECUS
FIGURE 5—NEW CONFIGURATION 'B' DEPICTED WITH INDEPENDENT SCI RX/TX LINES PER EACH EMISSION ECU
6.3.3D IAGNOSTIC C ONNECTOR M ULTIP LEXING—Multiplexing of the SAE J1962 diagnostic connector terminals shall
be required by the diagnostic tester to support the two vehicle configurations as follows:
a.Configuration 'A'—For Configuration 'A', connector pins 6 and 14 shall be multiplexed between SCI
functionality and ISO 15765-4 CAN functionality under software control. SCI connections to pins 6 and
14 shall not electrically interfere with ISO 15765-4 CAN operation. Both pins must transition
simultaneously between data link types when requested. When the SCI mode is selected by the tester,
both pins 6 and 14 must support SCI transmit with Vpp flash strobe function under software control.
The default settings for the SCI channel function are 7812.5 bps with flash strobe 'OFF'. Connector pin
7 shall function as either an SCI receiver, or an ISO 9141-2 bi-directional transceiver under software
control. SCI connections to pin 7 shall not electrically interfere with ISO 9141-2 operations, and shall
be able to be pulled to either vehicle battery or 5 V DC under programmable control.
b.Configuration 'B'—For Configuration 'B', connector pins 9 and 12 shall be configured for SCI
functionality. When the SCI mode is selected by the tester, both pins 9 and 12 must support SCI
transmit with Vpp flash strobe function under software control. Either connector pin transitions
independently with SCI mode enabled. The default settings for the SCI channel function are
7812.5bps with flash strobe 'OFF'. Connector pins 7 and 15 shall function as either an SCI receiver, or
an ISO 9141-2 transceiver under software control. SCI connections to pins 7 or 15 shall not electrically
interfere with ISO 9141-2 operations, and shall be able to be pulled to either vehicle battery or 5 V DC
under programmable control.
For additional details regarding the multiplexing of the Vpp flash strobe requirements during a flash reprogramming session, please refer to Section 9 “Reprogramming Requirements”.
6.4Media Characteristics—The SCI physical media shall be defined as a dual-wire, unshielded, twisted-pair
interface.
6.4.1I MPEDANCE—Impedance characteristics shall be dictated by the interface circuitry as specified in the ECU
receiver/transmitter reference circuits in 6.5.
6.4.2I NTERFACE C A BLE C ONSIDERATIO NS—The diagnostic tester interface cable shall not exceed a maximum of
5m in length.
The interface cable may be constructed using one of the following methods:
a.By using two jumper connectors in the interface cable, backward compatibility between Configuration
'A' and Configuration 'B' can be supported with minimal tester software overhead. This is
accomplished by shorting connector pins 6 and 12 together for engine ECU and connector pins 9 and
14 together for transmission ECU, and promotes a single interface cable usage for old vs. new
connector configurations. The same goal can be accomplished using a cable adapter with the jumpers
integrated into the adapter. However, the interface cable and/or adapter connector will constitute
special requirements for DaimlerChrysler Corporation (Chrysler Group) vehicles, and as such, may be
a less desirable solution. Additionally, this set-up cannot be used for CAN vehicles.
b.By not using any jumper connectors in the interface cable, tester detection of connector configuration
can be supported through software polling techniques. Several methods for ECU response detection
via connector pins 7 and 15 are possible. This approach allows a standard interface cable to be used
for all vehicles.
6.5ECU Receiver/Transmitter Reference Circuits—The following figures depict functionally equivalent SCI
receive and transmit circuits for an ECU.
6.5.1SCI R X L INE—The ECU receive circuit shall contain provisions to support SCI communications as well as
Vpp flash strobe requirements multiplexed on the same line by the diagnostic tester. A typical ECU receive circuit is shown illustrated in Figure 6.
FIGURE 6—REPRESENTATIVE ECU RECEIVER CIRCUIT WITH TYPICAL COMPONENT VALUES
6.5.2SCI T X L INE—The ECU transmit circuit shall contain an open-collector style circuit to drive a diagnostic tester
receive circuit such as the one illustrated in Figure 7. The tester must provide adequate pull-up resistance as
shown.
FIGURE 7—REPRESENTATIVE ECU TRANSMITTER CIRCUIT WITH TYPICAL COMPONENT VALUES
7.Data Link Layer—The SCI Data Link Layer is responsible for transferring data between the SCI Physical
Layer and the Message Application Layer. The SCI Data Link Layer defines the data frame elements, format, length, inter-frame timing, and error handling conditions.
7.1Data Frame Definition—Asynchronous data transmission implies that each data frame shall be transmitted
individually. This section defines the grouping of data bits that comprise an SCI data frame. A data frame is defined as one complete transmission of information delineated by the start of frame (start bit) and end of frame (stop bit) identifiers. These start and stop bits define the boundaries of a single data frame for the receiver to properly interpret.
7.1.1L E NG TH A ND F ORMAT—The data frame size shall be defined as ten (10) bits in length (i.e., one start bit, eight
data bits, and one stop bit with no parity). The format of the data frame shall be defined as follows:
a.One (1) Start Bit:One start bit with logic “0” (low) for one bit time duration. The start bit is defined as the
first binary element transmitted in the asynchronous transmission of a data frame. It is used to uniquely
identify the beginning of a data frame transmission to synchronize the receiver to an active session.
b.Eight (8) Data Bits:Eight data bits transmitted from Least Significant Bit (LSB) to Most Significant Bit
(MSB). The data bits comprise the byte or character value contained in the data frame bounded by the
start and stop bits.
c.One (1) Stop Bit:One stop bit with logic “1” (high) for one bit time duration. The stop bit is defined as
the last binary element transmitted in the asynchronous transmission of a data frame. It is used to
uniquely identify the end of a data frame transmission to return the receiver to an idle condition.
d.No Parity Bit:No parity bit in the default data fram
e. Therefore, no parity checking is available in the
transmitted data frame.
Figure 8 illustrates this pattern:
FIGURE 8—THIS EXAMPLE DEPICTS THE DATA FRAME TRANSMISSION OF CHARACTER $69
7.2Inter-Frame Timing—An SCI receiver shall be capable of receiving 255 consecutive data frames with zero (0)
inter-frame delay. Inter-frame delay is defined as the time between the end of one data frame and the start of the next data frame. Zero inter-frame delay implies that data is being transferred as fast as the data rate allows. If a diagnostic tester cannot receive a stream of 255 consecutive data frames with zero (0) inter-frame delay, then a slower data rate should be negotiated between the diagnostic tester and the ECU.
Although the SCI communication link is a full-duplex serial interface, in some communication sessions a half-duplex mode is required. Half-duplex mode implies that the SCI communication system is capable of bi-directional communications but only in one direction at a time. In the half-duplex mode, every data frame sent by the diagnostic tester is “echoed” by the ECU. The tester shall not send the next data frame until receiving the expected echo from the ECU. Upon receiving the echo, the tester shall assume the ECU is ready for the next sequential data frame. Although the ECU shall echo the appropriate data frame as intended, this shall not imply that the command sequence has been fully serviced by the ECU. An additional delay time may be
required by the ECU for processing the request before a command sequence has been completed. This half-duplex mode allows the timing sequence to be completely managed by the diagnostic tester. This strategy prevents data frame overruns from occurring, but also effectively limits the data throughput. That is, the diagnostic tester shall wait for the echoed response character before sending the next request. This is illustrated in Figure 9:
FIGURE 9—TWO-FRAME MESSAGE REQUEST/ACKNOWLEDGEMENT SEQUENCE WITH A TWO-FRAME MESSAGE RESPONSE DURING A DIAGNOSTIC SESSION
Additionally, multiple-frame command sequences may be sent to an ECU without echoing each character. In this case, a response shall occur within a given timeframe. Otherwise, a communication timeout event shall be declared, and the ECU shall disregard the entire command sequence. This is illustrated in Figure 10:
FIGURE 10—MULTIPLE-FRAME MESSAGE DOWNLOAD SEQUENCE WITH A MULTIPLE-FRAME ACKNOWLEDGEMENT DURING A REPROGRAMMING SESSION The following timing parameters in Figure 11 shall apply to all communication modes:
FIGURE 11—TIMING DELAY PARAMETERS LISTED AS A FUNCTION OF COMMUNICATION MODE
7.3Error Handling
7.3.1E RRO R D ETECTION—There are several distinct types of detectable SCI communication errors. A diagnostic
tester and ECU shall monitor for framing, overrun, and noise communication errors. The SCI “frame level”
communication errors are defined as follows:
a.Framing Error:A framing error is set when the SCI receiver detects a logic “0” where a stop bit (logic
“1”) should occur. A framing error results when the frame boundaries in the received bit stream are not
synchronized with the receiver bit counter. This is usually caused by mismatched data rates between
receiver and transmitter. Note that a BRK condition may set a framing error.
b.Overrun Error:An overrun error is set when the SCI receiver has not transferred data from its internal
receive buffer before new data arrives. Data transfer between ECU and tester is inhibited until this
receive buffer can be cleared. Previous data in the receive buffer is still valid, but all data received after
the overrun condition was declared is discarded.
The SCI “bt level” communication errors are defined as follows:
c.Noise Error:A noise error is set when the SCI receiver has detected noise on a valid start bit, stop bit,
or data bit. A noise error results when the sampled bit in the received bit stream assumes different
states or an indeterministic state based on a sampling frequency of the logic level. The sampling
frequency is determined by the SCI receiver.
7.3.2E RRO R C ORRECTION/R ECOVERY—If an SCI communication error is detected, the SCI receiver shall reject the
request, discard any message contents, and refrain from sending any response character. Possible recovery strategies include:
a.Wait for a communication session timeout
b.Request a retransmission of the previous data frame
c.Request a change in communication parameters (e.g., reduction in data rate)
In the high-speed mode, the ECU shall monitor for framing and overrun communication errors. If a framing or overrun error is detected, the ECU shall record the error event to accumulate the number of occurrences.
When a maximum number of ten (10) errors have been detected, the ECU shall reset the data rate to the default low-speed mode and clear the error accumulation counter to zero. The noise error is not tracked for frequency of occurrence in the high-speed mode.
In the low-speed mode, the ECU shall monitor for framing, overrun, and noise communication errors. If no communication errors are detected during a 100 milliseconds sampling period, re-establishment of the high-speed mode shall be allowed.
8.Message Application Layer—The Message Application Layer transforms SCI data frames received from the
Data Link Layer into application-specific messages. Additionally, the Message Application Layer maps application-specific messages back into data frames to be transferred by the Data Link Layer. The Message Application Layer can support many industry-standard or proprietary application-specific protocols.
Application-specific protocols that utilize the SCI communication link include the SCI Diagnostic Protocol for PCM Applications, and the SAE J2190 Diagnostic Protocol for PCM Applications as applied to the diagnosis of DaimlerChrysler Corporation (Chrysler Group) vehicles.
8.1Message Frame Structure—An SCI message frame shall be defined as an ordered collection of SCI data
frames. Since SCI is a dedicated point-to-point communication link, no message header is required for specifying the addressing format or error checking. This permits full usage of the communication bandwidth.
The message frame shall have the following free-form structure as shown in Figure 12:
Data bytes 1 to N shall comprise the message data area. The message data area may or may not contain error checking. The message length may vary depending on the application-specific protocol requirements.
FIGURE 12—ARBITRARY MESSAGE FRAME STRUCTURE FOR SUPPORT OF MULTIPLE PROTOCOLS 9.Reprogramming Requirements—The SCI communication link is utilized in the flash reprogramming of
emission-related powertrain devices. Additional requirements apply when reprogramming emission-related ECUs via the SCI communication link. To that end, this section defines the application of protective security mechanisms, hardware interlock requirements, and flash strobe requirements as applied to the reprogramming of emission-related ECUs.
9.1Security—The diagnostic tester shall secure the flash reprogramming process by retaining all required
reprogramming information off-board the vehicle (i.e., resident in the tester). The tester shall provide the ECU with the proper software routines, algorithms, and loaders containing the necessary instructions for download, checksum, erase, and program. These routines are only temporarily downloaded into volatile RAM on-board the ECU for the current diagnostic session. These functions shall only be allowed following the initialization of secured access to ECU boot-loader functions.
9.2Block Transfer—Data targeted for the reprogramming of a memory device shall be segmented into data
blocks for download into the ECU. The data block size, format, and integrity verification process shall be as defined below.
9.2.1L E NG TH A ND F ORMAT—The data block shall not exceed 4K bytes in length. The format of each block shall
minimally contain a header composed of the target memory address (defined as the absolute memory address location) followed by a block length identifier.
9.2.2V ERIFICATIO N—Data block verification can be performed using various procedures and methods. Most
commonly, a checksum is performed and verified from the data stream echoed by the ECU to the diagnostic tester. Data is downloaded into the ECU RAM by the tester, flashed into PROM, read from PROM, and compared to RAM on a per byte basis. It is then echoed back to the diagnostic tester. A final checksum of the entire program code shall be performed following completion of the flash process.
9.3Hardware Interlock—The hardware interlock shall be required to externally trigger the ECU into entering the
special boot-loader mode following hardware reset. This interlock enables a “flash-ready” mode not achievable through normal software control. It is used to enhance the secured process through the implementation of an additional protective safeguard. Since the vehicle is unable to generate the Vboot signal level required for initiating boot-loader mode, no boot-block functions can be inadvertently accessed. The hardware interlock is stimulated by the flash strobe voltage multiplexed on the ECU SCI receive line. Once the hardware interlock has been initiated, a hardware reset is required to permit the ECU to enter a “load-and-go” boot-loader mode to allow off-board routines to be downloaded and executed. The flash strobe signal is used as a comparative voltage on the Vboot control input for the ECU bootstrap software to detect. The hardware reset is
accomplished through cycling of the ignition key.
9.4Flash Strobe—The diagnostic tester shall be required to generate the external Vpp flash strobe voltage
necessary for erasing and programming on-board memory devices. The Vpp flash strobe voltage is needed to support the following four functions:
a.Initiating ECU boot-loader mode
b.Reading flash memory electronic signature (manufacturer and device codes)
c.Erasing flash memory
d.Programming flash memory
9.4.1V PP S PECIFICATIO N—The diagnostic tester shall generate the Vpp flash strobe voltage multiplexed on the
tester SCI transmit line. The requirements for the programmable power supply shall be defined as follows in Figure 13:
FIGURE 13—VPP FLASH STROBE ELECTRICAL PARAMETER VALUES
A switching power supply is recommended for use as the Vpp flash strobe (instead of a charge pump or
other device) in order to satisfy the fast stabilization time requirements.
9.4.2SCI/VPP M ULTIP LEXING—The diagnostic tester shall be capable of multiplexing signals between SCI data
communications and Vpp flash strobe. The diagnostic tester shall apply the flash strobe following download and execution of the erase routine. The flash strobe shall be applied for the entire duration of the erase event. After completion of the erase event, the tester shall download the programming routine to the ECU.
The first block of data to be programmed into the flash memory shall be transmitted to the ECU and saved into on-board RAM. Since the data needed to fully reprogram a flash memory device is larger than the available RAM resources in the ECU, the program code is segmented into data blocks or packets of specific length. Following a successful download of the first data block to the ECU, the diagnostic tester shall apply the flash strobe to the ECU. The ECU boot-loader routine shall have sufficient delay to allow the tester to generate the flash strobe voltage. This timing is dependent on the circuitry used to switch in the flash strobe signal. The programming routine previously downloaded and resident in on-board RAM writes the data into the flash memory space and echoes the programmed data back to the tester. Upon receiving all expected data, the tester shall power down the flash strobe signal thus allowing further transmission of data. This cycle continues until all blocks of data have been programmed. This repetitive process is depicted in Figure 14:
FIGURE 14—TESTER MULTIPLEXING OF THE SCI TX AND VPP FLASH STROBE
SIGNALS FOR A SINGLE DATA BLOCK TRANSFER EVENT
9.4.3T IME C RITICAL E VENTS—Time critical events are required to address timing and process constraints imposed
by certain request and response activities that necessitate some level of real-time intervention. Most notably, this is a requirement during the application and removal of the flash strobe voltage following the execution of the erase sequence or block download sequence for memory programming. The diagnostic tester should apply the flash strobe voltage within one character transmission of the last data byte of the block transfer.
The ECU shall allow a delay time for the settling and stabilization of the flash strobe voltage. This stabilization time (Ts) shall be measured from the reception of the last stop bit of the block transfer. If the flash strobe voltage has not stabilized within the allotted delay time, the ECU shall abort the reprogramming process. Following completion of the programming event, the tester shall remove the flash strobe so that SCI communications can recommence. This re-establishment of data communication allows further block transfers to occur.
PREPARED BY THE SAE VEHICLE E/E SYSTEMS DIAGNOSTIC STANDARDS COMMITTEE
Rationale—The purpose of this document is to specify the requirements necessary to fully define the Serial Data Communication Interface (SCI) used in the reprogramming of emission-related powertrain Electronic Control Units (ECU) in DaimlerChrysler Corporation (Chrysler Group) vehicles. It is intended to satisfy new regulations proposed by the federal U.S. Environmental Protection Agency (EPA) and California Air Resource Board (CARB) regulatory agencies regarding “pass-thru programming” of all On-Board Diagnostic (OBD) compliant emission-related powertrain devices. These requirements are intended to provide independent automotive service organizations and after-market test equipment suppliers the ability to reprogram emission-related powertrain ECUs for all manufacturers of automotive vehicles. These requirements are in addition to the approved OBD communication links previously specified and included in SAE J2534 Pass-Thru Programming, and constitute unique DaimlerChrysler Corporation (Chrysler Group) manufacturer-specific requirements. This specification will be referenced from within SAE J2534 as a technical information report.
Relationship of SAE Standard to ISO Standard—Not applicable.
Application—The purpose of this SAE Information Report is to specify the requirements necessary to fully define the Serial Data Communication Interface (SCI) used in the reprogramming of emission-related powertrain Electronic Control Units (ECU) in DaimlerChrysler Corporation (Chrysler Group) vehicles. It is intended to satisfy new regulations proposed by the federal U.S. Environmental Protection Agency (EPA) and California Air Resource Board (CARB) regulatory agencies regarding “pass-thru programming” of all On-Board Diagnostic (OBD) compliant emission-related powertrain devices. These requirements are necessary to provide independent automotive service organizations and after-market scan tool suppliers the ability to reprogram emission-related powertrain ECUs for all manufacturers of automotive vehicles.
Specifically, this document details the SCI physical layer and SCI data link layer requirements necessary to establish communications between a diagnostic tester and an ECU. It further specifies additional requirements for the application of a flash strobe voltage multiplexed on the SCI communication link for purposes of ECU reprogramming. This document does not specify the content or meaning of the application messages or diagnostic protocol to be transmitted on the SCI communication link. It only defines a generic method to transfer data between a diagnostic tester and an ECU, regardless of application messaging structure.
This specification will be referenced from within SAE J2534 Pass-Thru Programming as a technical information report. In this regard, the inclusion of the SCI communication link is in addition to the approved OBD communication links previously specified in SAE J2534, and constitutes unique DaimlerChrysler Corporation (Chrysler Group) manufacturer-specific requirements.
