Ignition Key Switch Test

WARNING: This page is about a different car, the 2003 Acura 3.2TL. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For more key-in beeper information, refer to the CIRCUIT DIAGRAM and CONTROL UNIT INPUT TEST .

When the ignition key is not removed, 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.

Remove the steering column upper and lower covers .
Disconnect the 7P connector.
