Test Description

WARNING: This page is about a different car, the 1995 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Test numbers refer to numbers on diagnostic chart.

If MIL driver circuit or ignition feed circuit to bulb is open, MIL will not illuminate.
Jumper Harness (J 35616-A) should be used instead of directly probing harness. This will prevent damage to harness.
MIL should go off after engine starts. If it does, problem is not present at this time. If light does not go off, drive circuit is shorted to ground or PCM is faulty.
If other codes exist, use other code charts first, then restart at beginning of this chart.
