Power Output Diagnostic Mode

You may use a power output diagnostic mode in the multifunction 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.
^ Set the park brake.
^ 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 three times.

During a normal operation, the multifunction alarm module will flash the interior lamps until the ignition switch turns OFF. If there is an internal short in the multifunction 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.
