Nubira SX Wagon L4-2.0L DOHC D-TEC MFI (1999)
Malfunction Indicator Lamp: Testing and Inspection
No Malfunction Indicator Lamp
NO MALFUNCTION INDICATOR LAMP
Circuit Description
When the ignition is turned ON, the Malfunction Indicator Lamp (MIL) will momentarily flash on and off, then it will remain on until the engine is
running if no Diagnostic Trouble Codes (DTC) are stored. Battery voltage is supplied through the ignition switch directly to the MIL telltale. The
powertrain control module (PCM)/engine control module (ECM) controls the MIL by providing a ground path through the MIL control circuit to turn on
the MIL.
Diagnostic Aids
An open ignition #5 fuse will cause the entire cluster to be inoperative, and may set DTC P1625.
Check the battery and ignition feed circuits for poor connections if the MIL is intermittent.
Any circuitry, that is suspected as causing an intermittent complaint, should be thoroughly checked for backed-out terminals, improper mating, broken
locks, improperly formed or damaged terminals, poor terminals-to-wiring connections or physical damage to the wiring harness.
