Audible Warning Device: Description and Operation
Chime Inputs/Outputs
Door Jamb/Ajar Switch
The doorjamb/ajar switch is a plunger type switch mounted in the B-pillar. When the driver's door is opened beyond a prescribed distance, the switch
contacts close signalling to the chime module that the door is open.
Internal to the chime module the left front door ajar input pin 10 is connected to pin 9, but there is a diode between the two pins which prevents the
right front and rear doorjamb/ajar switches from pulling the left front door ajar input LO. This internal connection allows the left front doorjamb/ajar
switch to also control the dome lamp.
Ignition And Key Alarm Switch Assembly
The key minder circuit is a set of contacts that are activated by the ignition module mechanical driver. When the switch is closed, the circuit pulls the
chime module current input to ground. The ground circuit is provided by a wire ground to the switch.
Rear Defogger Switch And Timer
The chime module provides the timing function and control of the rear defog system. When the rear defog switch is pressed for the first time in an
ignition cycle, the rear defog element and switch indicator will come On, and stay On for 15 minutes unless the ignition is turned to either the ACC or
LOCK position or the rear defog switch is pressed again to turn the system Off. Subsequent activations of the switch, prior to cycling the ignition,
when the rear defog is Off, will result in the same operation, except the time the defogger is On is reduced to 7.5 minutes
