It also includes an integratedquad port I2C multiplexer (MUX) to control SFPs or PoE modules. The VSC8584supports IEEE 802.1AE 128/256-bit MACsec protocols to meet the securityrequirements for protecting data traversing Ethernet LANs, and also includes Vitesse’spatent-pending distributed timing technology VeriTime™ that delivers the industry’smost accurate IEEE 1588v2 timing implementation. The VSC8584 device offers aseamless integration between IEEE 1588v2 and the MACsec engine with no loss ofprecision. The VSC8584 also supports a ring resiliency feature that allows a1000BASE-T connected PHY port to switch between master and slave timing withouthaving to interrupt the 1000BASE-T link.This document describes the architecture and usage of the VSC8584 Evaluation Board(VSC8584EV). The VSC8584EV may be used to evaluate a family of devices whichinclude VSC8584. These devices vary with respect to the number of ports, supportedinterfaces, and available features. This document specifically addresses the VSC8584device. The Quick Start section describes how to bring-up the evaluation board alongwith install and run the graphical user interface (GUI), used to control the evaluationboard.Figure 1.VSC8584EV Evaluation Board1.1ReferencesThe following reference documents provide additional information about the operationof the VSC8584 evaluation board.•VSC8564 Datasheet( https:///products/product.php?number=VSC8564 )•VSC8582 Datasheet( https:///products/product.php?number=VSC8582 )•VSC8575 Datasheet( https:///products/product.php?number=VSC8575 )•VSC8584 Datasheet( https:///products/product.php?number=VSC8584 )•IEEE1588v2 and SyncE – Applications and Operation Using Vitesse’sSynchronization Solution( /products/download.php?fid=4767&number=VSC8574 ) •VSC8584 GUI( https:///products/product.php?number=VSC8584 )2General DescriptionThe evaluation board in Figure 1 provides the user a way to evaluate the VSC8584device in multiple configurations. Four RJ-45 connectors are provided for coppermedia interfaces. The four SFP cages allow for evaluation of the fiber mediainterconnects. The MAC interface is provided via SMA connectors.For access to all of the features of the device, an external microcontroller is used toconfigure the on-board clock chip via a two wire serial bus and the VSC8584 via theMDIO bus. The graphical user interface (GUI) enables the user to access the registers.The evaluation board uses a Zarlink device to synthesize a 125MHz reference clocksignal from a 20MHz crystal which serves as the REFCLK input.2.1Key Features2.1.1Copper Port RJ45 ConnectionsPHY Ports 2 and 3 use UDE RTA 1648BAK1A with integrated magnetic while PHYPorts 0 and 1 use generic RJ45 connectors with discrete Pulse H5008 magnetics.2.1.2SGMII/QSGMII MAC SMASGMII SMA connections are provided for all PHYs while the QSGMII SMA connection isavailable only on PHY0.2.1.3Switch Block ControlSet the SW1 switch as shown in the figure below.Figure 2.SW1 Switch Control2.1.4Zarlink ZL30343 SyncE G.8262/SETSThe Zarlink ZL30343 is initialized by default to provide a 125MHz differential LVPECLclock to VSC8584 REFCLK inputs. (Note: the ZL30343 can be programmed to provideLVDS differential clock in conjunction with an LVDS termination provided for REFCLK,please refer to the Zarlink manual for programming its output drive.)Also, the ZL30343 can support synchronization with the VSC8584 PHY recovered clockfor SyncE operation. The ZL30343 is initialized to lock to a recovered clock output ifone is enabled and available from the VSC8584 PHY. If no recovered clock signal isavailable, then the ZL30343 will select the crystal oscillator (U16) as default referencesource for holdover operation. ZL30343 will indicate locked versus holdover status bydriving LED D33 or D34. See the Zarlink documentation for more discussionconcerning its operation. See the VSC8584 datasheet for configuring recovered clockoutput pin behavior.Please ensure three-way resistive connections R19 and R22 are appropriatelyconnected to feedback the VSC8584’s recovered clock outputs into the ZL30343device, if synchronization to a recovered clock source is desired.2.1.5External 1588 Clock OptionThe user may choose to provide an external 1588 REFCLK via SMA connections to J65and J66. Zero Ohm jumpers may need to be removed and or installed to connect viathese clock inputs. The board is built with connections for external 1588 REFCLK,unless otherwise indicated in documentation accompanying the specific boarddelivered.2.1.6External RefClk OptionThe user may choose to provide an external PHY REFCLK via SMA connections to J21and J23. Zero Ohm jumpers may need to be removed and or installed to connect viathese clock inputs. As per section 2.1.4 and unless otherwise indicated indocumentation accompanying the specific board, the board is built with a REFCLKconnection driven by the ZL30343, instead of using an external REFCLK source.2.1.71588 Daisy-Chain SPI Time-Stamping ConnectionThe VSC8584 device enables daisy-chaining multiple devices to reduce the number ofpins required to transmit time stamping information to system ASICs gathering IEEE1588 time stamps. For users with two or more 8584EV boards, the following single-ended connections shown below are required from the master device to slave device: •J75 pin 6 to J77 pin 6 (1588_SPI_CLK output → input)•J75 pin 4 to J77 pin 4 (1588_SPI_CS output → input)•J75 pin 2 to J77 pin 2 (1588_SPI_MISO output → 1588_SPI_MOSI input) See section 3.5.4 for register programming to enable this interface.Recommendation: for SPI daisy chaining use a Molex 10 pin ribbon cable with one-to-one connections.Figure 3.1588 Daisy-Chain SPI InterconnectOnce enabled along with proper initialization of the 1588 IP block, time-stamped 1588traffic in the egress direction will generate a similar sequence on the serializedtimestamp daisy-chain as shown in Figure 4. See the VSC8584 datasheet sectionabout Serial Time Stamp Output Interface for a more detailed functional description.Figure 4.1588 Daisy-Chain SPI Traffic Pattern (PHY port 3 egress)PHYADD= 32.1.8Network Interface Microcontroller CardA “Rabbit” microcontroller card is included to facilitate a software interface to theregisters on the VSC8584. The controller card has a hard coded static IP address.Refer to the label on the card for the value. This address is required by the user toinitiate communications via the board and the GUI.NOTE: The factory programmed Rabbit board IP address is: 10.9.70.193.3Quick Start3.1Connecting the Power SupplyThe evaluation board uses +5VDC to power the on-board regulators creating the+3.3V, +2.5V, and +1.0V rails which drive the devices as well as modules. Theevaluation board can be powered up using the power pack which provides the +5VDC.Simply plug the AC adaptor into a wall socket and the barrel end into J67 (see theupper right corner of Figure 1). Immediately the user should see several LEDs turnon.The user may alternately connect the board to a bench style power supply byconnecting the red banana plug to +5VDC and the black banana plug to ground. Ifthe supply provides 3A the board should come alive as described above.3.2PC Software Installation1.Download the ZIP file to the PC’s root directory, normally C:\.2.Extract to C:\3.Double click the icon to launch the GUI (It is acceptable to drag the icon tothe desktop)3.3Connecting the Board to the PCThe Rabbit board can interface with a PC either through a direct connection to the PC orif configured properly through a local area network. The latter option requires the userto configure the Rabbit’s IP address so as to properly reside on the user’s network.The IP address of the board should be written on the Rabbit network interfacedaughter board card. The default value should be 10.9.70.193. You will need to usethis IP address to initially access the board for operation or to change its IP address.3.3.1Changing the IP Address of the Board1.Determine and write down the new unique IP address you wish to change theboard to.2.Directly connect an Ethernet cable from a PC to the Rabbit board.NOTE: Some older PCs do not support auto-crossover on the Ethernet connectionso a cross-over cable may be needed.unch a DOS command window by clicking on the Start->Run button and typing“cmd”.4.Within the DOS command window type “Telnet”.5.In Telnet, connect to the Rabbit board’s address using the open command bytyping “open^10.9.70.XXX”.6.10.9.70.xxx where xxx is the value on your board from the factory (typically 193).7.You should have a prompt and be able to type help to get a list of commandsavailable on the Rabbit.a)If you are unable to connect, then most likely you will need to change the IPaddress of the connected PC to have the first 3 octets similar to the board byfollowing the subsequent steps.b)On the PC under Windows -> Control Panel ->Network Connections -> LocalArea Connection, right mouse click for Properties. Under the General tabhighlight Internet Protocol (TCP/IP) and click on Properties. From there enterthe new PC IP address such as 10.9.70.yyy where yyy is a unique value andNOT the same as the Rabbit board. Once complete, return to step 4.mand the board to change its IP address to the new one by typing into Telnetnow connected to the board the command: set ip <new IP address> <Enter>where <new IP address> is in the form xxx.xxx.xxx.xxx. Once you hit <Enter>the IP address will be changed and the Rabbit will save the value and reboot whichmay take approximately 1 minute. The Telnet session will disconnect from theboard.9.Change your PC IP address to the same IP network as the Rabbit board.10.Telnet to the Rabbit board.e the following commands to complete configuration of the Rabbit board:a)set netmask xxx.xxx.xxx.xxxb)set gateway xxx.xxx.xxx.xxxc)save env12.Please record and inform Vitesse of the new IP address of the board when youreturn so that Vitesse can connect to and reconfigure the board.13.Re-label the Rabbit board with the new IP.3.4Using the Control SoftwareConnect the VSC8584EV Rabbit microcontroller RJ-45 directly to the PC or through anetwork switch if properly configured. Apply +5VDC to the EVB.Launch the GUI by double-clicking the GUI shortcut located in C:\ViperGUI_4_67 or onthe desktop if it has been moved there. The GUI Connection window shown in Figure5 should appear.Figure 5.GUI Connection WindowTo make a connection to the EVB, click “Rabbit” and enter the IP address of the EVB,then click on “Connect”. The display next to the IP address window should change to“Connected”. If it does not, check the IP address, or your network configuration untilconnection with the EVB can be successfully established.Double-click on “MII Registers” and the window shown in Figure 6 should appear:Figure 6.MII Registers GUI WindowVerify the device is up and running by reading MII Register 0. It should read back0x1040. Reading back all 0’s or all 1’s indicates a problem. A checked box means thebit is set to “1,” if unchecked it is “0”.3.4.1Board Initialization and Running PHY ScriptsOnce the evaluation board connectivity has been established and confirmed, the PHYshould be initialized. Initialization can be accomplished by running an init-scriptsequence, such as performed by the pre- and post-reset functions of the PHY APIstandalone app.While the init-script sequence may not required for specific operational modes, an init-script sequence is highly recommended to ensure correct performance over thegreatest set of user scenarios for the PHY. After initialization is performed, refer tothe PHY Datasheet section on Configuring of the PHY and PHY Interfaces for thedesired application.In order to execute an init-script, double-click on “Run PHY Script” within the GUIConnection Window to launch the Run PHY Script window as shown in Figure 7. Thisenables a user to load a script to configure the device rather than navigating throughRegisters pages. Click “Load” button, browse to a desired script file via the pop-uppanel, finally click “Run” button. After execution is completed, you should see read-back values in decimal as shown in Figure 8.The script syntax is command, phy address (in decimal), register address (in decimal),and register content (in either hexadecimal or decimal).Figure 7.Run PHY Script GUI Window (after script is loaded)Figure 8.Run PHY Script GUI Window (after script is executed)3.4.2Copper Media Operation (1000BASE-T)A single register write and some external coax cables enables 1G Ethernet traffic to bereceived by the VSC8584 RJ-45 port, routed through the VSC8584 and externally viacoax loopback cables through the SGMII interface and transmitted back to the trafficsource on the same copper port. First configure the SerDes in SGMII mode by writingto Micro page 18’d. This is a global setting and does not need to be applied per port.Steps for external SGMII loopback:1.Set up the Copper traffic source (i.e., IXIA or Smartbits)2.Connect an Ethernet cable to an RJ-45 Port 0.3.Connect two matched coax cables, J1 – J4 and J2 – J5.4.Write using the “Micro Page Registers” window: 18’d 0x80F0.5.When “Micro Page” 18’d is read back, bit 15 will clear.6.Linkup bit is in MII Reg 1, bit 2 (MII 1.2), read twice to updateTraffic should be flowing.Steps for SGMII forwarding port 0 ↔ port 1:1.Set up the Copper traffic source (i.e., IXIA or Smartbits)2.Connect one Ethernet cable to RJ-45 Port 0, second cable to RJ-45 Port 1.3.Connect four matched coax cables as follows:J1 <TDIN0+> to J6 <RXDOUT1+>J2 <TDIN0-> to J7 <RXDOUT1->J5 <RXDOUT0-> to J10 <TXDIN1->J4 <RXDOUT0+> to J9 <TXDIN1+>4.Write using the “Micro Page Registers” window: 18’d 0x80F0.5.When “Micro Page” 18’d is read back, bit 15 will clear.6.Linkup bit is in MII Reg 1, bit 2 (MII 1.2), read twice to updateTraffic should be flowing.3.4.3Fiber Media Operation (1000BASE-X)Follow all steps in section 3.4.2 with fiber media connection to (IXIA) and add thefollowing steps.1.Write using the “Micro Page Registers” window: 18’d 0x8FC1.

See the label on the card for the value.This address is required by the user to initiate communications via the board and the GUI.Note: The factory programmed Rabbit board IP address is 10.9.70.193.1. 2. 3. 1. 2. 3. 4. 5. 6. 7. a. b. 8. 9. 10. 11. 4Quick Start 4.1Connecting the Power SupplyThe evaluation board uses +5VDC to power the on-board regulators creating the +3.3V, +2.5V, and +1.0V rails which drive the devices as well as modules. The evaluation board can be powered up using the power pack which provides the +5VDC. Simply plug the AC adaptor into a wall socket and the barrel end into J67 (see the upper right corner of Figure 1). Immediately the user should see several LEDs turn on.The user may alternately connect the board to a bench style power supply by connecting the red banana plug to +5VDC and the black banana plug to ground. If the supply provides 3A the board should come alive as described above.4.2PC Software InstallationDownload the ZIP file to the PC’s root directory, normally C:\.Extract to C:\Double click the icon to launch the GUI (It is acceptable to drag the icon to the desktop)4.3Connecting the Board to the PCThe Rabbit board can interface with a PC either through a direct connection to the PC or if configured properly through a local area network. The latter option requires the user to configure the Rabbit’s IP address so as to properly reside on the user’s network.The IP address of the board should be written on the Rabbit network interface daughter board card. The default value should be 10.9.70.193. You will need to use this IP address to initially access the board for operation or to change its IP address.4.3.1Changing the IP Address of the BoardDetermine and write down the new unique IP address you wish to change the board to.Directly connect an Ethernet cable from a PC to the Rabbit board.Note : Some older PCs do not support auto-crossover on the Ethernet connection so a cross-over cable may be unch a DOS command window by clicking on the Start->Run button and typing “cmd”.Within the DOS command window type “Telnet”In Telnet, connect to the Rabbit board’s address using the open command by typing “open 10.9.70.^XXX”.10.9.70.xxx where xxx is the value on your board from the factory (typically 193).You should have a prompt and be able to type help to get a list of commands available on the Rabbit.If you are unable to connect, then most likely you will need to change the IP address of the connected PC to have the first 3 octets similar to the board by following the subsequent steps.On the PC under Windows -> Control Panel → Network Connections → Local Area Connection, right mouse click for Properties. Under the General tab highlight Internet Protocol (TCP/IP) and click on Properties. From there enter the new PC IP address such as 10.9.70.yyy where yyy is a unique value and NOT the same as the Rabbit board. Once complete, return to step 4.Command the board to change its IP address to the new one by typing into Telnet now connected to the board the command: set ip <new IP address> <Enter> where <new IP address> is in the form xxx.xxx.xxx.xxx. Once you hit <Enter> the IP address will be changed and the Rabbit will save the value and reboot which may take approximately 1 minute. The Telnet session will disconnect from the board.Change your PC IP address to the same IP network as the Rabbit board.Telnet to the Rabbit board.Use the following commands to complete configuration of the Rabbit board:11. a. b. c. 12. 13. Use the following commands to complete configuration of the Rabbit board:Set netmask xxx.xxx.xxx.xxx Set gateway xxx.xxx.xxx.xxx Save envPlease record and inform Vitesse of the new IP address of the board when you return so that Vitesse can connect to and reconfigure the board.Re-label the Rabbit board with the new IP.4.4Using the Control SoftwareConnect the VSC8574EV Rabbit microcontroller RJ-45 directly to the PC or through a network switch if properly configured. Apply +5VDC to the EVB.Launch the GUI by double-clicking the GUI shortcut located in C:\TeslaGUI_4_65 or on the desktop if it has been moved there. The GUI Connection window shown in Figure 3 should appear.Figure 3 • GUI Connection WindowTo make a connection to the EVB, click “Rabbit” and enter the IP address of the EVB, then click on1. 2. 3. 4. 5. 6. 1. 2. 3. 4. 5. To make a connection to the EVB, click “Rabbit” and enter the IP address of the EVB, then click on “Connect”. The display next to the IP address window should change to “Connected”. If it does not, check the IP address, or your network configuration until connection with the EVB can be successfully established.Double-click on “MII Registers” and the window shown in Figure 4 should appear:Figure 4 • MII Registers GUI WindowVerify the device is up and running by reading MII Register 0. It should read back 0x1040. Reading back all 0’s or all 1’s indicates a problem. A checked box means the bit is set to “1”, if unchecked it is “0”.4.4.1Copper Media Operation (1000BASE-T)A single register write and some external coax cables enables 1G Ethernet traffic to be received by the VSC8574 RJ-45 port, routed through the VSC8574 and externally via coax loopback cables through the SGMII interface and transmitted back to the traffic source on the same copper port. First configure the SerDes in SGMII mode by writing to Micro page 18’d. This is a global setting and does not need to be applied per port.Set up the Copper traffic source (ie: IXIA or Smartbits)Connect an Ethernet cable to an RJ-45 Port 0.Connect two matched coax cables, J1 – J4 and J2 – J3.Write using the “Micro Page Registers” window: 18’d 0x80F0.When “Micro Page” 18’d is read back, bit 15 will clear.Linkup bit is in MII Reg 1, bit 2 (MII 1.2), read twice to updateTraffic should be flowing.4.4.2Fiber Media Operation (100BASE-FX)Follow all steps in section 2.53 with fiber media connection to (IXIA) and add the following steps.Write using the “Micro Page Registers” window: 18’d 0x8FD1.

4E n d W r e n c hT h eAll Subaru vehicles manufactured since 1996 are equipped with a second genera-tion on-board diagnostic system (OBD II), as required by government regulations.The emissions warranty for many of these vehicles has ended, and some are finding their way to independent repair shops for emissions system repairs.While the implementation of the OBD II standards was intended to bring a level of standardization to emissions diagnostics and repairs, vehicle manufacturers and individual vehicles will continue to have unique design characteristics and repair techniques. This article offers a collection of repair tips and tricks collected from the field, focused on late model Subaru emissions system diagnosis, service and repair.EGR Flow MalfunctionsOBD II diagnostic trouble code (DTC) P0400 indicates an exhaust gas recirculation flow malfunction. It’s important to keep in mind that this is a functional check of the EGR system. A P0400 DTC usually does not indicate an electrical fault, but rather a failure of one of the components in the EGR system.The OBD II system tests EGR operation only under specific conditions. A test failure must occur on two consecutive ‘trips’ before the OBD II system will trigger the dash-board CHECK ENGINE light to alert the driver of an emissions system problem. Several factors may contribute to a DTC P0400, so a systematic approach is needed to quickly determine what might, or might not, be at fault.• Begin with a visual inspection of the EGR system. It’s important to point out that not all Subaru engines are equipped with an EGR system. Only those that are will be capable of triggering a P0400.•Check all vacuum control hoses running between the EGR solenoid valve, back pressure transducer and EGR valve. All hoses must be properly installed. Look for any kinking or loose hoses that would impede the flow of vacuum through the system.•Metal pipes dip below the throttle cables. Condensation may form in this area,causing corrosion on the inside of the metal pipes. If this corrosion is allowed to get bad enough, it may block the flow of vacuum through the pipes and trigger a DTC P0400. Remove the vacuum hoses from the pipes, then blow through the pipes with compressed air to make certain they are fully open.System ServiceSubaruEmissions10En d W r e n c hT h e• A metal pipe also connects the back-pressure transducer to the EGR valve.The rubber hose at the backpressure transducer end of the pipe may become deteriorated and begin to leak due to engine heat. A weak vacuum signal will keep the EGR valve from fully opening when commanded, which may also cause a DTC P0400.•Check the components themselves.Carbon from the EGR valve may back up into the backpressure transducer port, affecting its flow. Engine exhaust heat may also damage the diaphragm inside the backpressure transducer,keeping it from operating properly. As exhaust backpressure increases, pressure on the transducer diaphragm increases and more vacuum is allowed to flow to the EGR valve. The transducer can be checked with a pressure pump, but there are no specifications for exactly when and how much it should open for a specific pressure.•The last item to check is the EGR valve.An EGR valve with heavy carbon deposits will not be able to flow the required amount of exhaust gas during the the P0400 functional test. If the flow is low, a DTC P0400 will be stored in the pending code memory. Remove the EGR valve and clean it as necessary. Remember, P0400 is a two trip DTC.The EGR system must fail the test twice on two consecutive trips. So it may be difficult to determine whether you’ve successfully repaired the problem. It may be difficult for most customers to under-stand why you need to keep their cars for an extended period of time to verify your repairs. There is an easier way,however:•After repair are completed, clear all DTCs from the control unit’s memory. •Locate the green diagnostic connectors under the driver’s side dash and plug them together.•Plug in your OBD II-compatible scanner and take the vehicle for a test drive. •The EGR system functional test only occurs under specific condition. Simply stated, the vehicle must be running at a steady speed of approximately 55 mph for a specified period of time. Consult the appropriate service manual for a detailed explanation.•If the vehicle successfully completesthe EGR system functional test, no ‘temporary’ or ‘pending’ codes will be stored in the control unit and displayed on the scanner screen.•Disconnect the green diagnostic con-nectors and return the vehicle to the customer.Cylinder Misfire CodesIf you encounter cylinder misfire codes on Subaru vehicles equipped with an OBD II system, check the past service history to see if the vehicle’s fuel filter was changed recently.There is a short period of time when the vehicle is first started, after the filter has been changed, when the cylinders do not get the fuel charge they should.This may translate into a slight cylinder misfire.If the fuel filter was changed recently,clear the codes and test drive the vehicle.Chances are good the codes will not return if the filter change was the cause of the problem.Other Misfire Code CausesThe control unit constantly monitors the signal from the crankshaft and camshaft position sensors. Suddenchanges in the signals from these sensors could indicate that the engine is either speeding up or slowing down in an uncontrolled manner. These sudden changes may be caused by cylinder mis-fires. Since one of the OBD II system’s main jobs is to protect the catalytic converter, cylinder misfires are a high system priority.Several things can contribute to inter-mittent or constant cylinder misfire DTCs.Not surprisingly, many of them are the same things that have been causing cylinder misfires for as long as there have been internal combustion engines:•Carefully inspect the ignition coil(s).Look for signs of carbon tracking or physical damage to the coils. Anything that will impede the flow of current to the spark plugs may cause a cylinder misfire DTC.•Check the ignition wires for damage or wear.•Remove and inspect the spark plugs.Some Subaru models are equipped with long-life platinum spark plugs.These are not, however, unlimited life spark plugs. The vehicle owner mayh cn e14E n d W r e n c hT h efor cylinder #1. The pin location of this power supply can be found in the Control Unit Module I/0 Signal pages of the appropriate Service Manual.Impreza Air Suction Valve NoiseSome Subaru Impreza models areequipped with air suction valves (ASV).These valves may make some noise for brief periods of time during initial cold startup and driving. The noise sounds very much like lifter noise.This condition is considered to be a normal operating condition and norepairs should be made. Also remember that this is an emission control device and can not be legally tampered with.The noise reported usually shows up at ambient temperatures of approximately 40 degrees F or lower, with engine speeds of 2,000 RPM or higher. The noise may go away during this time if your foot is removed from the gas pedal and may return if the throttle is again applied.Once the engine has warmed up slightly,the noise goes away and will not return until the engine has had an extended cool down period (usually overnight).If you have a customer complaining of a cold engine noise, it may very well be the ASVs that are causing the noise.Question the owner about when the noise occurs and how the vehicle is being operated before attempting any repairs.1980-1989 Subaru Vehicles Pressure T esting of Fuel T ank During State Emission T estThe U.S. Environmental Protection Agency has issued evaporative technical guidance requirements for conducting a functional pressure test of the evaporative system on pre-1996 model year vehicles as part of state emission inspections. The evaporative pressure testing of the fuel tank system consists of identifying and clamping off the vapor hose line from the fuel tank as close to the evaporative canister as possible. The vehicle shall fail the test if the fuel vapor control sys-tem loses more than six inches of water pressure over a period of 120 seconds,starting from a stabilized pressure of 14±1 inch of water.Certain early model Subaru vehicles were built with a vapor hose connecting to the evaporative canister with a small spring inserted to maintain the hoseintegrity while under vacuum condi-tions. Under state I/M Program condi-tions of clamping this vapor hose, the spring prevents the clamp from creating a proper seal, which results in a false pressure test failure.Subaru strongly recommends that state I/M programs exempt the models listed below from the functional evapo-rative pressure test.Subaru Affected Model Years Modelwith Spring Hose 2 Door (Hatchback)All 1980-894-Door Sedan All 1980-84Hardtop All 1980-84, except turbo models (1984)Station Wagon All 1980-84, except turbo models (1983/84)MPV (BRAT)All 1982-88, except turbo models (1983/84)For pre-1996 Subaru vehicles, which are deemed testable, Subaru provides the following recommendation:Warning! Improper clamping may dam-age the vapor hose. Clamping should only be performed using a non-cutting surface grip pliers or similar tool.Ensure that the fuel tank system is pres-surized in an even and consistent man-ner with the applied pressure notexceeding 14.5 inches of water or fuel system damage may occur. Improper pressurizing may also damage the 2-way rollover valve.Model Y ear 1998 Changes In P0440 Evap Operation1998 model year vehicles with theEnhanced Evaporative Emissions Control System no longer electrically cycle their fuel tank Pressure Control Valves (PCV)to regulate fuel tank pressure on a regular basis. However, the valve is still cycled electrically while performing the OBD diagnostic function for Code P0440. What this means is that, while test driving a vehicle for this code, the Select Monitor will no longer indicate any PCV opera-tion just after the beginning of driving and will no longer indicate periodic operation of the valve throughout the drive. It will still, however, show opera-tion of the PCV valve when the computer begins to enter the diagnostic phase of driving for P0440 when the PCV valve is on and the vent valve comes on along with the canister purge to draw a low pressure on the tank. The PCV valve can still be operated in the compulsory valve operation mode.。
