Key Reminder Switch: Testing and Inspection

NOTE: Refer to Integrated control unit the circuit diagram of the key-in beeper, and to Integrated control unit input test for the input test of the beeper circuit.

When the ignition key is not removed, the key-in beeper in the integrated control unit senses ground through the closed ignition key switch. When you open the driver's or passenger's door, the beeper circuit senses ground through the closed door switch. With ground at the "A1" and "A2" or "A3" terminals, the beeper sounds.

1. Remove the dashboard lower cover and knee bolster.

Ignition Key Switch Test:

2. Disconnect the 7P connector from the main wire harness.
3. There should be continuity between the No. 2 and No. 4 terminals when the ignition key is in the ignition key cylinder. There should be no continuity with the ignition key removed.
