Audible Warning Device: Description and Operation
Battery Run Down Protection
The Battery Run Down Protection Feature is made up of three independent features: The Parasitic Power Control, the Inadvertent Power Control, and the
Courtesy Lights Control.
Parasitic Power Control
The Parasitic Power Control output of the Multi-Function Alarm Module supplies voltage to the Remote Keyless Entry (RKE) Module and Radio.
The output timer will shut off power to all of the above components where one of these two conditions occurs:
^
Vehicle travels for less than 15 miles since battery power is applied to the Multi-Function Alarm Module and is parked for 3 days following
the last ignition cycle.
^
Vehicle travels for more than 15 miles since battery power is applied to the Multi-Function alarm module and is parked for 24 days following
the last ignition cycle.
Inadvertent Power Control
The Inadvertent Power Control output of the Multi-Function Alarm Module supplies voltage to these lamps: Courtesy, Header, Rear Quarter,
Vanity Mirror, Reading, I/P Compartment and Luggage Compartment. For more information, refer to Interior Lights. See: Lighting and Horns
Courtesy Lights Control
The Courtesy Lights Control output of the Multi-Function Alarm Module supplies ground to the Courtesy and Dome lamps. For more information,
refer to Interior Lights. See: Lighting and Horns
Power Output Diagnostic Mode
There is a Power Output Diagnostic Module in the Multi-Function Alarm Module that can be used to run a quick check on the operation of the
Parasitic Power Control, the Courtesy Lights Control and the Inadvertent Power Control outputs. It is activated after all of the following actions
have been performed:
^
Close all doors.
^
Set Park Brake.
^
Turn Interior Lights on using Panel Dimmer Switch.
^
Turn Ignition Switch to "RUN" and, before 15 seconds pass, perform these steps.
-
Open the RH front door
-
Cycle the Headlamp Switch from "PARK" to "OFF" 3 times.
During normal operations (no trouble found), the Multi-Function Alarm Module will flash the Interior Lights until the ignition switch is turned to
"OFF." In the event of an internal short is found in the Multi-Function Alarm Module, the module will chime as follows:
^
1 chime every 3 seconds - Inadvertent output failure
^
2 chimes every 3 seconds - Courtesy output failure
^
3 chimes every 3 seconds - Parasitic output failure
NOTE: The Multi-Function Alarm Module can now be reset by a battery disconnect. This can be accomplished by removing the INT LAMP Fuse.
