Ignition Switch: Testing and Inspection

IGNITION SWITCH TEST

WARNING: On vehicles equipped with an airbag, refer to passive restraint systems before attempting steering wheel or steering column component diagnosis or service. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury.

1 Disconnect and isolate the battery negative cable.

2 Remove the steering column shrouds and disconnect the ignition switch harness connector.

3 With the ignition switch in the On position, check for continuity between the ignition switch fused B+ circuit terminal and the ignition switch output (start) circuit terminal. There should be no continuity If OK, go to Step 4. If not OK, replace the faulty switch.

4 With the ignition switch held in the Start position, check for continuity between the ignition switch fused B+ circuit terminal and the ignition switch output (start) circuit terminal. There should now be continuity If not OK, replace the faulty switch.
