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.


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


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