Key-In Warning Buzzer

Voltage is supplied at all times to the Audio Alarm Module through the STOP-HZ Fuse and the ORN (140) wire. With the key in the Ignition Switch and the Ignition Switch in ACC, LOCK or OFF, the chime or buzzer will sound if the left door is open.

With the door open, the LH Door Jamb Switch closes to ground. This provides a ground to the Audio Alarm Module through the TAN (159) wire, the Key-In Ignition Switch, and the LT ORN (80) wire. The chime or buzzer will sound as long as the door is open or the key is in the Ignition Switch.
