Multi-Function Alarm Module
The multi-function alarm module uses an inadvertent power control in
order to supply power to the following lamps:
| • | The instrument panel compartment lamps |
| • | The luggage compartment lamps |
The left front door jamb switch turns on the interior lamps through
the multi-function 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 multi-function 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 multi-function 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:
The interior lamps will turn off immediately when the vehicle begins
to move.
Voltage is applied to the multi-function alarm module at all times through
the INT LAMP fuse. The multi-function alarm module applies voltage at
all times to the alarm's internal feature, the inadvertent power control.
Voltage is applied to the multi-function alarm module through the ALARM
fuse when the ignition is in one of the following positions:
Voltage is applied at all times to the cigar lighter through the CIG
fuse.
Battery Run Down Protection
Inadvertent power control output of the multi-function alarm module
applies voltage to the following lamps:
| • | The instrument panel compartment lamp |
| • | The luggage compartment lamp |
If the ignition switch is in the OFF position for more than 20 minutes,
the output timer will shut off power to all of the above lamps. If the vehicle
traveled less than 24 km (15 mi) since battery voltage applied
to the module, the output timer will shut off the lamps after 2 to 4 minutes.
You may reset the inadvertent power control output by one of the following
methods:
| • | Open the left front door. |
| • | Close the left front door. |
| • | Turn the ignition switch to RUN. |
| • | Turn OFF any interior lamps that were left on accidentally. |
Power Output Diagnostic Mode
You may use a power output diagnostic mode in the multi-function alarm
module in order to run a quick test on the operation of the following outputs:
| • | The courtesy lamps control |
| • | The inadvertent power control |
The power output diagnostic mode activates after you perform all of
following actions:
| • | Close all of the doors. |
| • | Turn the ignition switch to RUN. |
Before 15 seconds pass, perform the following steps:
| • | Open the right front door. |
| • | Cycle the headlamp switch from OFF to PARK 3 times. |
During a normal operation, the multi-function alarm module will flash
the interior lamps until the ignition switch turns OFF. If there is an internal
short in the multi-function alarm module, the module will chime in the
following patterns:
| • | One chime every 3 seconds means that there is an inadvertent
output failure. |
| • | Two chimes every 3 seconds means that there is a courtesy
output failure. |
