Battery Run Down Protection

The Battery Run Down Protection feature is made up of two independent features: the Parasitic Power Control and 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 and Remote Keyless Entry (RKE) Module. The output timer will shut off power to the above components 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.

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 Lighting and Horns. Lighting and Horns

Power Output Diagnostic Mode
There is a Power Output Diagnostic Mode 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 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 "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. 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 ALARM Fuse.
