DESCRIPTION

1996 MODEL OBD-II MIL STATUS "ON" AND I/M PROGRAM TEST FAILURES

During a check of the On-Board Diagnostic (OBD) system on some model year 1996 Mitsubishi vehicles, it was found that the malfunction indicator lamp (MIL) is commanded "ON" even though there may be no diagnostic trouble codes (DTC's) stored at that time. This error was discovered during OBD-II inspection /maintenance (I/M) checks involving a small number of vehicles. This error does not affect the effective operation of the OBD-II system during actual driving conditions. Monitoring of the vehicle emissions control systems and all other mandated functions (including triggering the MIL "ON" if a DTC is stored) remain fully operational. The foregoing issue only arises during I/M type checks of the system.
