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, the key-in beeper circuit of the multiplex control unit in the 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. When both switches are closed (driver's door and ignition), the key-in beeper in the gauge assembly is activated.

1. Remove the steering column upper and lower covers.




2. Disconnect the 6P connector.
3. Check for continuity between the No.1 and No.2 terminals.
- There should be continuity with the key in the ignition switch.
- There should be no continuity with the key removed.
