General Description

The Multi-function Alarm Module supplies power to all Courtesy, Header, Reading, I/P Compartment and Luggage Compartment Lights with a feature called Inadvertent Power Control.

The Front Door Handle Switches turn on the Interior Lights through the Multi-function Alarm Module. When either front door handle is raised, its Front Door Handle Switch closes, grounding and input to the module. The module then grounds the Courtesy Lights and Header Light to turn them on. The Rear Door Jamb Switches turn on the Interior Lights directly, without working through the Multi-function Alarm Module.

The Panel Dimmer Switch in the Turn/Hazard-Headlight Switch Assembly also turns on the Interior Lights independent of the door switches or the Multi-function Alarm Module.

An interior lights-on delay is provided by the Multi-function Alarm Module after a front door has been opened. The lights remain on for about 40 seconds or until the Ignition Switch is turned to "RUN." This 40 second lights-on delay is reduced to 4 seconds if a front door is opened within 2 minutes after the Ignition Switch is moved from the "RUN," "START" or "BULB TEST" position. In addition, the interior lights will turn off immediately when the vehicle begins to move.

Voltage is applied at all time through the ALARM Fuse to the Multi-function Alarm Module. The Multi-function Alarm Module then applies voltage at all times to its internal feature: Inadvertent Power Control. With the Ignition Switch in "RUN," "BULB TEST" or "START," voltage is applied to the Multi-function Alarm Module through the GAGES Fuse. Voltage is also applied at all times through the CTSY Fuse to the Cigar Lighter.
