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 only be displayed by using a Scan Tool connected to the data link connector (DLC): o Breeze 1 o Neon 2


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