Audible Warning Device: Description and Operation
Battery Run Down Protection
The Battery Run Down Protection feature is made up of two 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 Radio. The output timer will shut OFF power to
the radio when 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.
Courtesy Lights Control
The Courtesy Lights Control output of the Multi-function Alarm Module supplies ground to the Courtesy and Dome Lights. For more information,
refer to Interior Lights. See: Lighting and Horns
Inadvertent Power Control
The Inadvertent Power Control output of the Multi-function Alarm Module supplies voltage to these lights: Courtesy, Header, Rear Quarter,
Vanity Mirror, Reading, I/P Compartment, and Luggage Compartment. For more information, refer to Interior Lights. See: Lighting and Horns
Power Output Diagnostic Mode
There is a Power Output Diagnostic Mode in the Multi-function Alarm Module that can he 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:
^
Turn Interior Lights on using Panel Dimmer Switch.
^
Close all doors.
^
Turn Ignition Switch to "RUN" and, before 15 seconds pass, perform these steps:
-
Open the RH front door.
-
Cycle the Headlight Switch from the "PARK" to "OFF" 3 times.
During normal operation (no trouble found), the Multi-function Alarm Module will flash the Interior Lights for approximately 1 minute and return
to normal operation. In the event of a short found in the Inadvertent output circuit (CKT 1732), Courtesy output circuit (CKT 156), or the Parasitic
output circuit (CKT 1733), the module will chime as follows:
^
1 chime every 3 seconds - Inadvertent output failure
^
2 chime 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 ALARM Fuse.
