Malfunction Indicator Lamp: Testing and Inspection
Malfunction Indicator Light And Boost Gauge Circuit
To test the Malfunction Indicator (check engine) Light, located in the instrument cluster, turn the ignition switch on. The light should illuminate. This
insures that the light is operative. If the light bulb does not illuminate the most likely fault is a defective light bulb. If the light tests good the other
possible causes are, the ECU not supplying ground at terminal 106, the wiring harness or instrument cluster printed circuit board.
