General information
- Engine control module (ECM) incorporates self-diagnosis function.
- Malfunction indicator lamp (MIL) will illuminate if certain faults are recorded.
- ECM operates in backup mode if sensors fail, to enable vehicle to be driven to workshop.
- Trouble codes can be displayed by using a Scan Tool connected to the data link connector (DLC) 1
- Trouble codes can also be displayed by the MIL
NOTE: The use of a Scan Tool is essential to obtain full diagnostic information.
Accessing
- Ensure ignition switched OFF.
- Within 5 seconds tum ignition key as follows:
o Ignition ON-OFF-ON-OFF-ON.
- MIL should be flashing.
- Count MIL flashes and compare with trouble code table.
o The first group of short flashes indicate the ‘TENS’ [2] [A) of the trouble code.o The second group of short flashes indicates the ‘UNITS’ [2] [D) of the trouble code.o A short pause separates each flash [2] [B].o A long pause separates each set of flashes [2] [C].o A 4 second pause separates each trouble code [2] [E).o For example: Trouble code 32 displayed [2].
Erasing
- Trouble codes can be erased by using a Scan Tool connected to the data link connector (DLC) or as follows:
- Ensure ignition switched OFF.
- Disconnect battery ground cable for 30 seconds minimum.
- Reconnect battery ground cable.
- Repeat checking procedure to ensure no data remains in ECM fault memory.
NOTE: Disconnecting battery ground lead will erase trouble codes but may also erase memory from electronic units such as radio.
