General information

  • 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 the MIL or by using a Scan Tool connected to the data link connector(s) (DLC).

Accessing

Flash codes

  • Within 5 seconds switch the ignition key ON-OFF-ON-OFF-ON.
  • Count MIL flashes. Note trouble codes.
  • Each trouble code consists of two groups 1 [A].
  • The first group of flashes indicate the ‘tens’ of the trouble code.
  • The second group of flashes indicate the ‘units’ of the trouble code.
  • A short pause separates ‘tens’ and ‘units’ 1 [B].
  • A long pause separates each trouble code 1 [C].
  • For example: Trouble code 21 displayed 1.
  • End  of test sequence  indicated by  trouble code 55.

P codes & Hex codes

• Trouble codes can be displayed by using a Scan Tool connected to the data link connector(s) (DLC) 2

Erasing

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