故障代码及故障定义

（辽宁富士电梯）系统故障代码表详细故障代码分析电梯门机故障。

ER0 电梯门机故障。

现象1：开门或关门限位失效，门不开关；现象2：门机无电或门机控制开关动作引起门不动；现象3：无开关门指令ER02：门联锁在电梯运行过程中断开。

现象1：运行过程中，门刀与门轮冲撞把门锁断开。

现象2：如FU16 设置为ON 时，系统判断门锁是否闭合与关门限位信号有关。

如FU16 设为ON 时，关门限位不可靠也会造成ER03 保护。

现象3：主板检测门锁信号使用了两路检测，为触点输入，X4 X23 为门锁回路电压检测，如门锁回路电压不够高，标准要求是AC110V，如低于AC100V 时，高压输入不稳定也会造成报ER02 的故障。

现象4：ER02 故障发生在顶层，曳引机为同步，同步曳引机的抱闸动作延迟时间过长时，容易造成电梯冲上极限，出现该现象时，急停故障前有02 故障发生。

(正常到顶层停车时，系统下闸后，使能方向会保持设定的时间，brake off time 使电梯闸没闭合稳时，变频器仍有力矩输出。

如门锁意外断开，门锁触点把变频器使能切断，造成滑车极限。

现象5：变频门机由于开关门的信号从控制柜直接引线从随行电缆下到轿顶。

如干扰过大时会在运行过程中，门机控制器错误接收到开门指令，误开门造成ER02 故障，出现该情况时，可以在轿顶上安装开关门继电器，控制柜先在关门信号驱动轿顶开关门继电器，再由继电器的触点控制门机控制器开关门。

该方法能有效防止开关门信号干扰造成门机误动作。

ER03：变频器故障。

现象1：变频器故障，根据故障代码确定故障原因。

现象2：某些变频器由于上电时间过长，超过了系统的上电等待时间，系统报变频器故障，该情况可以不用处理，变频器上电完成后系统将自动恢复。

现象3：如果变频器产生过流保护，而其保护前同一时间内有ER02 或ER10 等保护，一般都是由于前面的保护立即停车造成的，系统其他保护恢复后将自动恢复。

ER04：主板检测到的运行方向与给定的运行方向相反。

To minimize service confusion, fault codes should not be used to indicate the absence of problems or the status of parts of the system (e.g., powertrain system O.K., or MIL activated), but should be confined to indicate areas in need of service attention.Some ranges have been expanded beyond 100 numbers by using the hexadecimal base 16 number system. ISO/SAE Controlled Codes (Core DTCs)—ISO/SAE controlled diagnostic trouble codes are those codes where industry uniformity has been achieved. These codes were felt to be common enough across most manufacturers' applications that a common number and fault message could be assigned. All unspecified numbers in each grouping have been reserved for future growth. Although service procedures may differ widely amongst manufacturers, the fault being indicated is common enough to be assigned a particular fault code. Codes in this area are not to be used by manufacturers until they have been approved by ISO/SAE.5.3Manufacturer Controlled Codes (Non-Uniform DTCs)—Areas within each alpha designator have beenmade available for manufacturer-controlled DTCs. These are fault codes that will not generally be used by a majority of the manufacturers due to basic system differences, implementation differences, or diagnostic strategy differences. Each vehicle manufacturer or supplier who designs and specifies diagnostic algorithms, software, and diagnostic trouble codes are strongly encouraged to remain consistent across their product line when assigning codes in the manufacturer controlled area. For powertrain codes, the same groupings should be used as in the ISO /SAE controlled area, i.e., 100's and 200's for fuel and air metering, 300's for ignition system or misfire, etc.Code groupings for non-powertrain codes will be specified at a later date.While each manufacturer has the ability to define the controlled DTCs to meet their specific controller algorithms, all DTC words shall meet SAE J1930.5.4Body System Groupings5.4.1B0XXX ISO/SAE C O NTROLLED5.4.2B1XXX M ANUFACTURER C ONTROLLED5.4.3B2XXX M ANUFACTURER C ONTROLLED5.4.4B3XXX R ES ERVE D BY D O CUMENT5.5Chassis System Groupings5.5.1C0XXX ISO/SAE C ONTRO LLE D5.5.2C1XXX M ANUFACTURER C O NTROLLED5.5.3C2XXX M ANUFACTURER C O NTROLLED5.5.4C3XXX R ESERVED BY D O CUMENT5.6Powertrain System Groupings—DTC Numbers and Cescriptions are Given in Appendix B5.6.1P0XXX ISO/SAE C O NTROLLED5.6.2P1XXX M ANUFACTURER C ONTROL5.6.3P2XXX ISO/SAE C O NTROLLED5.6.4P3XXX M ANUFACTURER C ONTROLLED A ND ISO/SAE R ES ERV ED5.7Network Groupings—DTC Numbers and Descriptions are given in Appendix C5.7.1U0XXX ISO/SAE C ONTRO LLE D5.7.2U1XXX M ANUFACTURER C O NTROLLED5.7.3U2XXX M ANUFACTURER C O NTROLLED5.7.4U3XXX R ESERVED6.Diagnostic Trouble Code Descriptions—Each specified fault code has been assigned a description toindicate the circuit, component or system area that was determined to be at fault. The descriptions are organized such that different descriptions related to a particular sensor or system are grouped together. In cases where there are various fault descriptions for different types of faults, the group also has a “generic”description as the first code/message of the group. A manufacturer has a choice when implementing diagnostics, based on the specific strategy and complexity of the diagnostic.Where more specific fault descriptions for a circuit, component, or system exist, the manufacturer should choose the code most applicable to their diagnosable fault. The descriptions are intended to be somewhat general to allow manufacturers to use them as often as possible yet still not conflict with their specific repair procedures. The terms “low” and “high” when used in a description, especially those related to input signals, refer to the voltage, frequency, etc. at the pin of the controller. The specific level of “low” and “high” shall be specified by each manufacturer to best meet their needs.For example, in diagnosing a 5 V reference Throttle Position Sensor (TP Sensor), if the input signal at the Powertrain Control Module (PCM) is stuck at near 0 V, a manufacturer has the flexibility to select from either of two codes - P0120 (Throttle/Pedal Position Sensor/Switch A Circuit) or P0122 (Throttle/Pedal Position Sensor/ Switch A Circuit Low Input), depending on the manufacturer's diagnostic procedures. If the input signal at the PCM is stuck at near 5 V, a manufacturer has the flexibility to select from either of two codes - P0120 (Throttle/ Pedal Position Sensor/Switch A Circuit) or P0123 (Throttle/Pedal Position Sensor/Switch A Circuit High Input), depending on the manufacturer's diagnostic procedures. If the input signal at the PCM is stuck at 1.5 V at idle instead of the expected 1.0 V, the manufacturer has the flexibility to select from either of two codes - P0120 (Throttle/Pedal Position Sensor/Switch A Circuit) or P0121 (Throttle/Pedal Position Sensor/Switch A Circuit Range/Performance Problem), depending on the manufacturer's diagnostic procedures. The root cause of the higher than expected TP Sensor voltage may be either a faulty TP Sensor, corrosion in the TP Sensor connections or an improperly adjusted throttle plate. Identification of the root cause is done using the diagnostic procedures and is not implied by the DTC message, thus allowing the manufacturer the flexibility in assigning DTCs Change requests.7.Change Requests—Use this form to pass your request.Request Form for New SAE J2012 SAE Controlled DTCWhat is the purpose of the component, circuit, or system?Example: Exhaust Gas Recirculation.What is the purpose of the diagnostic?Example: detect low EGR flowRequested Group NumberRequested DTC NumberRequested DTC NomenclatureExample: EGR Low Flow DetectedRequested by:Phone/FaxEmailAddressDate:Please send completed form(s) to:SAE Headquarters755 West Big Beaver RoadSuite 1600Troy, MI 48084USAATTN: SAE J2012 PowertrainCommittee Chairman8.Notes8.1Marginal Indicia—The change bar (l) located in the left margin is for the convenience of the user in locatingareas where technical revisions have been made to the previous issue of the report.

Appendix Bshows applications for recommended industry common trouble codes for the powertrain control system. These include systems that might be integrated into an electronic control module that would be used for controlling engine functions, such as fuel, spark, idle speed, and vehicle speed (cruise control) as well as those for transmission control. The fact that a code is recommended as a common industry code does not imply that it isa required code (legislated), an emission related code, nor that it indicates a fault that will cause themalfunction indicator to be illuminated.TABLE A1—DTC NAMING GUIDELINES FOR SIGNALS FROM COMPONENTSComponent/System SAE J19301)AcronymSAEJ19301)Modifier(if used) 1)Noun Name1Circuit1)Intermittent(if used) 1)State(if used) 1)Parameter(if used) 1)Location(if used) 1)Throttle Position TP Sensor Circuit Low Voltage Throttle Position TP Sensor Circuit PerformanceManifold AbsolutePressureMAP Sensor Circuit High VoltageEngine CoolantTemperatureECT Sensor Circuit Low Voltage Intake Air Temperature IAT Sensor Circuit High Voltage Vehicle Speed Sensor VSS included inacronymCircuit High VoltageVehicle Speed Sensor VSS included inacronymCircuit IntermittentHeated Oxygen Sensor HO2S included inAcronymHeaterCircuitHeated Oxygen Sensor HO2S included inAcronymHeater Circuit Low Voltage Bank (B1)Sensor 1 (S1)Idle Air Control IAC Valve Circuit Low VoltageMass Air Flow MAF Sensor Circuit High FrequencyMass Air Flow MAF Sensor Circuit PerformanceKnock Sensor KS included inacronymModule SensorCircuit Bank 1Knock Sensor KS included inacronymModule SensorCircuit PerformanceCrankshaft Position CKP Sensor CircuitEvaporative Emissions EVAP CanisterPurgeValve CircuitEngine Speed RPM Input CircuitAir Conditioning A/C ClutchStatusN/A Circuit Low VoltageHeated Oxygen Sensor HO2S Circuit TransitionTime Ratio Bank 1 (B1) Sensor (S1)Heated Oxygen Sensor HO2S Circuit Insufficient SwitchingBank 1 (B1)Sensor 1 (S1)Distributor Ignition DI Low ResolutionCircuitIntermittentDistributor IgnitionDIHigh Resolution CircuitNOTE 1) The Service Information uses Component/System from SAE J1930 or Acronym from SAE J1930, Modifier, Noun Name, Circuit, Intermittent, State, Parameter, and Location.TABLE A2—DTC NAMING GUIDELINES FOR SIGNALS TO COMPONENTSComponent/SystemSAE J19301)Acronym SAE J19301)Modifier (if used)1)Noun Name1)Control 1)Circuit 1)Intermittent (if used) 1)State (if used)1)Parameter (if used) 1)Location (if used) 1)Malfunction Indicator lamp MIL included in acronymControl Circuit Injector N/A Control Circuit Fan Control FC Relay 1Control Circuit Fan Control FC Relay 2Control Circuit Low Exhaust Gas RecirculationEGR Solenoid Control Circuit High Secondary Air Injection AIR Solenoid Control Circuit HighEvaporative Emissions EVAP Purge Solenoid Control Circuit Air Conditioning A/C ClutchRelay Control Circuit Idle Air Control IAC Valve Control Circuit Low Ignition Control IC N/A included in acronym Circuit Low Voltage Ignition ControlIC N/A included in acronym Circuit High VoltageTorque Converter ClutchTCCSolenoidControlCircuitStuck onNOTE 1) The Service Information uses Component/System from SAE J1930 or Acronym from SAE J1930, Modifier, Noun Name, Circuit, Intermittent, State, Parameter, and Location.TABLE A3—DTC NAMING GUIDELINES INVOLVING SEVERAL COMPONENTS OR SYSTEMSComponent/SystemSAE J19301)Acronym SAE J19301)Modifier 1)System 1)Intermittent 1)State 1)Parameter 1)Location 1)Exhaust Gas Recirculation EGR System Fuel TrimFT System LeanBank 1Secondary Air InjectionAIRSystemBank 1NOTE 1) The Service Information uses Component/System from SAE J1930 or Acronym from SAE J1930, Modifier, Noun Name, Circuit, Intermittent, State, Parameter, and Location.TABLE A1—DTC NAMING GUIDELINES FOR SIGNALS FROM COMPONENTSComponent/SystemSAE J19301)Acronym SAEJ19301)Modifier (if used) 1)Noun Name 1Circuit1)Intermittent (if used) 1)State (if used) 1)Parameter (if used) 1)Location (if used) 1)APPENDIX B(NORMATIVE)POWERTRAIN SYSTEM DIAGNOSTIC TROUBLE CODEB.1P00XX Fuel and Air Metering and Auxiliary Emission ControlsTABLE B1—P00XX FUEL AND AIR METERING AND AUXILIARY EMISSION CONTROLS DTC number DTC naming Location P0001 Fuel Volume Regulator Control Circuit/OpenP0002 Fuel Volume Regulator Control Circuit Range/PerformanceP0003 Fuel Volume Regulator Control Circuit LowP0004 Fuel Volume Regulator Control Circuit HighP0005 Fuel Shutoff Valve "A" Control Circuit/OpenP0006 Fuel Shutoff Valve "A" Control Circuit LowP0007 Fuel Shutoff Valve "A" Control Circuit HighP0008 Engine Position System Performance Bank 1 P0009 Engine Position System Performance Bank 2 P0010 a) "A" Camshaft Position Actuator Circuit Bank 1 P0011 a) "A" Camshaft Position -

故障码解读-回复故障码是现代汽车诊断系统中用来显示和存储车辆故障信息的一种代码，它可以帮助汽车技师快速准确地找到故障原因，以便进行修复。

故障码一般由一串数字和字母组成，可以分为标准故障码和厂商特定故障码两种类型。

标准故障码是由美国汽车工程师学会（SAE）制定的国际标准码，而厂商特定故障码是针对不同汽车品牌和模型的自定义码。

一、故障码的定义故障码的定义分为两部分：故障类型和故障位置。

故障类型表示车辆出现了哪种类型的故障，如发动机故障、传动系统故障等；故障位置表示故障发生在哪个系统或者哪个零部件上，如点火系统、燃油系统等。

故障码通常由一个字母和数个数字组成。

字母部分表示故障类型，常见的有P（Powertrain，动力系统故障）、C（Chassis，底盘系统故障）、B（Body，车身系统故障）、U（Unknown，未知系统故障）等；数字部分表示故障位置，每个位置对应一个特定的故障点或故障部件。

例如，故障码P0301表示发动机第一气缸的点火故障，而故障码C1234表示底盘系统某个传感器的故障。

二、故障码的读取要想读取故障码，首先需要一个扫描工具，也叫做故障码读取器或故障码扫描仪。

这种工具可以通过汽车的OBD接口与车辆的诊断系统进行通信，并读取和解析故障码。

OBD（On-Board Diagnostics）是指安装在行驶中的汽车上的故障自动诊断系统。

通过OBD接口，汽车的诊断系统可以与外部设备进行通信，包括扫描工具、检测设备等。

OBD接口通常位于汽车驾驶室内的仪表板下方，有一块盖子可以打开，暴露出16个引脚的接口。

使用扫描工具读取故障码的步骤如下：1.找到汽车的OBD接口，通常位于驾驶室内的仪表板下方，打开盖子，插入扫描工具的接口。

2.启动汽车的电源，但不需要发动引擎。

3.根据扫描工具的使用说明，设置通信协议和读取模式。

4.等待扫描工具与汽车的诊断系统建立通信。

5.一旦成功建立通信，扫描工具将读取故障码并显示在屏幕上。

dtc故障等级定义
《dtc故障等级定义》
DTC，即故障代码，是汽车电子控制单元（ECU）存储的故障信息。

每个DTC都有一个故障等级，用来表示故障的严重程度。

一般来说，DTC故障等级可以分为以下几个级别：
1. P级故障：表示主要故障，可能会导致车辆性能下降或排放增加。

这类故障大多是由于发动机或排放系统出现问题引起的，需要尽快处理。

2. C级故障：表示底层控制模块故障，可能会影响车辆操作或安全性。

这类故障大多是由于ABS、空调、底盘控制等系统出现问题引起的，需要及时检修。

3. B级故障：表示车身控制模块故障，可能会影响车身系统操作。

这类故障大多是由于车门、窗户、座椅等系统出现问题引起的，需要及时修复。

4. U级故障：表示通信故障，可能会导致车辆某些系统之间无法正常通信。

这类故障大多是由于CAN总线或其他通讯系统出现问题引起的，需要及时检修。

故障等级的定义，有助于车主和维修技师了解故障的严重程度，采取相应的处理措施。

在遇到DTC故障码时，可根据故障等级快速确定处理优先级，并及时进行维修保养，确保车辆的安全和性能。
