Multifunction Alarm Module

The multifunction alarm module uses an inadvertent power control in order to supply power to the following lamps:
^ The courtesy lamps
^ The header lamps
^ The reading lamps
^ The instrument panel compartment lamps
^ The luggage compartment lamps

The left front door jamb switch turns on the interior lamps through the multifunction alarm module. This is done by grounding circuit 394. When the left front door is opened, the switch closes. This action grounds and blocks the input to the module. The module then grounds the courtesy lamps and the header lamp in order to turn the courtesy lamps and the header lamp on. The following switches turn on the interior lamps by grounding the circuit 395 from the multifunction alarm module:
^ The right front door jamb switch
^ The rear door jamb switch

The panel dimmer switch provides a ground circuit for the interior lamps. This action turns on the interior lamps independent of the door switches.

The remote control door lock receiver grounds the interior lamps for approximately 40 seconds when one of the following conditions apply:
^ A door unlock signal is received by the remote control door lock receiver module
^ The ignition switch is turned to the RUN position.

The multifunction alarm module provides an interior lamps-on delay after the left front door has been opened. The lamps remain on until one of the following apply:
^ 40 seconds has elapsed.
^ The ignition switch is turned to the run position.

The 40 second lamps-on delay is sometimes reduced to 4 seconds. This reduction occurs if a front door is opened within 2 minutes after the ignition switch is moved out of one of the following positions:
^ RUN
^ START
^ BULB TEST

The interior lamps will turn off immediately when the vehicle begins to move.

Voltage is applied to the multifunction alarm module at all times through the INT LAMP fuse. The multifunction alarm module applies voltage at all times to the alarm's internal feature, the inadvertent power control. Voltage is applied to the multifunction alarm module through the ALARM fuse when the ignition is in one of the following positions:
^ RUN
^ BULB TEST
^ START

Voltage is applied at all times to the cigar lighter through the CIG fuse.
