Circuit Description
When the ignition is turned on, the MIL will momentarily flash on then off. When no Diagnostic Trouble Codes (DTCs) are stored, the MIL will
then remain on until the engine is running. The battery voltage is supplied through the ignition switch directly to the MIL telltale. The Powertrain
Control Module (PCM) controls the MIL by providing a ground path through the MIL control circuit in order to turn on the MIL.
Diagnostic Aids
An open ignition fuse causes the MIL to be inoperative.
Check any circuitry that is suspected of causing an intermittent problem for the following conditions:
-
Improper mating
-
Broken locks
-
Improperly formed or damaged terminals Physical damage to the wiring harness
