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 (DLC).


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 (DLC):
  • Breeze [2]
  • Neon [3]


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