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.


  • 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).
