Hi black ice 101,

 

Thanks for using Just Answer, in order to properly diagnose the problem you will need a DVOM (Digital Volt Ohm Meter) which can be purchased at your local auto parts store for about $50.00 or less. I am sending you the test procedures, hope this helps you out.

Generic Electronic Module, GEM Illuminated Entry, Explorer

The illuminated entry system assists vehicle entry by illuminating the vehicle interior lamp.

The system consists of four main components: generic electronic module, door latch switch, door ajar switch and wiring harness.

The interior lamp switch is a grounding type leaf switch and is attached to the front door latch by one screw.

 

Interior Courtesy Lamp Control

The following are inputs used for controlling the interior courtesy lamps to the generic electronic module.

  • all door ajar switches (including liftgate)
  • door handle switches
  • illuminated entry request - from RAP module
  • two step unlock - door disarm switches

All interior lights will shut off after 25 seconds (if all doors are closed) or:

  • immediately after the ignition switch is turned to the RUN position
  • or if the vehicle speed is above 8 km/h (5 mph).

If no wake up command is received and any of the doors are left open, the interior lights will turn off after 40 minutes when the battery saver times out.

 

The system is activated by raising the door handle.

This action momentarily closes a switch mounted on the front door latch, which completes the ground circuit of the generic electronic module and switches the system on. The vehicle interior lamps turn on, remain on for approximately 25 seconds, then automatically turn off. During this 25 second period, the system can be manually deactivated by turning the ignition switch to either RUN or ACC position.

The system will be activated every time the door handles are operated. Opening the interior lamp switch from the inside of the vehicle will not activate the system.

If the door handle is held up indefinitely so that the interior lamp switch is continuously closed, the system will operate as normally and turn off after 25 seconds. At the completion of this cycle, if the door handle is still in the raised position, the system will remain off, and it will be impossible to activate the system from the other door handle until the raised door handle is returned to its normal position. This function is built into the logic circuitry of the system to prevent battery discharge, should the door handle be intentionally propped up or become jammed in any way.
