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.
  • Malfunction indicator lamp (MIL) will illuminate or flash if certain faults are recorded.
  • ECM operates in backup mode if sensors fail, to enable vehicle to be driven to repair shop.

Accessing

• Trouble codes can only be displayed by using a Scan Tool connected to the data link connector o Achieva/Alero/Cutlass 1 o Eighty Eight/lntrigue/Silhouette 2 Achieva-eighty-eight1Achieva-eighty-eight2

Erasing

• After the faults have been rectified, the manufacturer recommends that trouble codes are erased by using a Scan Tool connected to the data link connector (DLC).
