Mitsubishi OBD / OBD2 Codes >> Expo/LRV 2.4L – Mirage 1.5/1.8L (1995 – 2002)

ModeL Year Engine identification System
Expo/LRV 2.4L – Federal 1996 4G64 MPI
Expo/LRV 2.4L FWD – California 1995-96 4G64 MPI
Mirage 1.5/1.8L 1995-02 4G15/4G93 MPI

General information

  • Engine control module (ECM) incorporates self-diagnosis function.
  • Malfunction indicator lamp (MIL) will illuminate if certain faults are recorded.
  • ECM operates in backup mode if sensors fail, to enable vehicle to be driven to workshop.

Accessing

  • Trouble codes can be displayed by using a Scan Tool connected to the data link connector (DLC):
o Expo/LRV – [1]
o  Mirage – [2]

Erasing

  • Trouble codes can be erased by using a Scan Tool connected to the data link connector (DLC) or as follows:
  • Ensure ignition switched OFF.
  • Disconnect battery ground cable for 30 seconds minimum.
  • Reconnect battery ground cable.
  • Repeat checking procedure to ensure no data remains in ECM fault memory.

NOTE: Disconnecting battery ground lead will erase trouble codes but may also erase memory from electronic units such as radio.
