Malfunction Indicator Lamp: Testing and Inspection

Instrument Cluster Component Locations:

To test the 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.

���/d��/���/Check Engine Light Circuit:

If the light tests good the other possible causes are, the ECU not supplying power (check pin #14 of connector), the wiring harness or instrument cluster printed circuit board (refer to ELECTRICAL AND ELECTRONIC DIAGRAMS).
