Key Reminder Switch: Testing and Inspection

Ignition Key Switch Test

NOTE: For more key-in beeper information, refer to the circuit diagram and input test.

When the ignition key is in the ignition switch, the key-in beeper in the driver's multiplex control unit senses ground through the closed ignition key switch. When you open the driver's door, the beeper circuit senses ground through the closed door switch.

1. Remove the steering column upper and lower covers.




2. Disconnect the 7P connector.

NOTE: Lock tab (A) points down when installed.

3. Check for continuity between the No. 1 and No. 3 terminals.
- There should be continuity with the key in the ignition switch.
- There should be no continuity with the key removed.

4. If the continuity is not as specified, replace the ignition key switch.
