General information

Refer to the front of this manual for general test conditions, terminology, detailed descriptions of wiring faults and a general trouble shooter for electrical and mechanical faults.
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.

Accessing

Trouble codes can be displayed by using a Scan Tool connected to the data link connector (DLC) 1.

Erasing – except Spectra 2004

After the faults have been rectified, 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 lead for 20 seconds minimum.
Reconnect battery lead.
Repeat checking procedure to ensure no data remains in ECM fault memory.

NOTE: Disconnecting battery ground lead may also erase memory from electronic units such as radio.

Erasing – Spectra 2004

Trouble codes can only be erased by using a Scan Tool connected to the data link connector (DLC).
