A number of codes and descriptions are repro- duced below as an example of the detailed infor- mation that is available from a self-diagnosis system. The data relates to the Bosch Motronic 1.7 Diagnostic techniques 17 Figure 2.6 Test the voltage at a connection with care 18 Advanced automotive fault diagnosis and 3.1. Fault code lists are available in publica- tions such as those by ‘Autodata’ and ‘Autologic’. FCR Description code 000 No faults found in the ECU 001 Fuel pump relay or fuel pump relay circuit 001 Crank angle sensor (CAS) or circuit (alternative code) 002 Idle speed control valve circuit 003 Injector number 1 or group one circuit 004 Injector number 3 or circuit 005 Injector number 2 or circuit 006 Injectors or injector circuit. 012 Throttle position switch or circuit 016 CAS or circuit 018 Amplifier to ECU amplifier circuit 019 ECU 023 Ignition amplifier number 2 cylinder or circuit 024 Ignition amplifier number 3 cylinder or circuit 025 Ignition amplifier number 1 cylinder or circuit 026 ECU supply 029 Idle speed control valve (ISCV) or circuit 031 Injector number 5 or circuit 032 Injector number 6 or injector group two circuit 033 Injector number 4 or circuit 036 Carbon filter solenoid valve (CFSV) or circuit 037 Oxygen sensor (OS) or circuit 041 Mass airflow (MAF) sensor or circuit 046 ECU 048 Air conditioning (AC) compressor or circuit 050 Ignition amplifier cylinder number 4 or circuit 051 Ignition amplifier cylinder number 6 or circuit 054 ECU 055 Ignition amplifier or circuit 062 Electronic throttle control or circuit 064 Ignition timing (electronic) 067 Vehicle speed sensor (VSS) or circuit 067 CAS or circuit 070 OS or circuit 073 Vehicle speed sensor (VSS) or circuit 076 CO potentiometer (non-cat) 077 Intake air temperature sensor (ATS) or circuit 078 Engine coolant temperature sensor (CTS) or circuit 081 Alarm system or circuit 082 Traction control or circuit 083 Suspension control or circuit 085 AC compressor or circuit 100 ECU 200 ECU 201 OS control or circuit 202 ECU 203 Ignition primary or circuit 204 Electronic throttle control signal or circuit 300 Engine 2.6.3 Clearing Fault codes can be cleared from the ECU mem- ory in two ways: ● using the facilities of a fault code reader (scan- ner) to clear the memory; ● disconnecting the battery earth lead for about two minutes (does not always work however). The first method is clearly recommended because disconnecting the battery will also ‘reset’ many other functions such as the radio code, the clock and even the learnt or adaptive functions in the ECUs. tải về 7.07 Mb.
