Troubleshooting Hints - Interior Lights

Perform before beginning System Diagnosis

NOTE:
^ If vehicle is left for 24 or more days, or 3 days if less than 15 miles without the Ignition Switch being put in "RUN", the Keyless Entry and Illuminated Entry and Parasitic Power features will be disabled to decrease parasitic battery drain. Putting the Ignition Switch in "RUN" will restore these features.
^ Interrupting battery voltage to the Multi-Function Alarm module by disconnecting the vehicle's battery or disconnecting the module will cause the interior lights-on delay to be only 2 to 4 minutes, until the vehicle has travelled more than 15 miles with battery power restored to the module.
^ The Multi-function Alarm Module controls Interior Lights and generates chime alarms, refer to Audible Warning Device. It also controls Automatic Door Lock, refer to Lock, Doors and Seat Belt Release Solenoids, refer to Seat Belts. Seat Belt Systems
Verify that all chime alarms operate before proceeding with following diagnostic test. If any chime alarms do not operate, Refer to Audible Warning Device Audible Warning Device

1. If none of the Courtesy Lights work from the Keyless Entry, but are otherwise OK, refer to Keyless Entry. Keyless Entry
