Pinpoint Test K: The Illuminated Entry Is Inoperative When Using The Remote Transmitter

Normal Operation 

The illuminated entry provides courtesy lighting whenever the lighting control module (LCM) receives a lamps on/doors unlock request from the remote keyless entry (RKE) transmitter. The LCM provides the voltage for the courtesy lamps.

This pinpoint test is intended to diagnose the following: 

• RKE transmitter
• LCM

PINPOINT TEST K: THE ILLUMINATED ENTRY IS INOPERATIVE WHEN USING THE REMOTE TRANSMITTER 

1. K1 CHECK FOR CORRECT RKE OPERATION 
   • Using the RKE transmitter, lock and unlock the doors.
   • Do the doors lock and unlock? 
   1. YES  : Go to  K2.
   2. NO  : REFER to HANDLES, LOCKS, LATCHES & ENTRY SYSTEMS article to continue diagnosis of the RKE system.
2. K2 CHECK THE OPERATION OF THE COURTESY LAMPS 
   • Open the driver door.
   • Do the courtesy lamps illuminate? 
   1. YES  : Go to  K3.
   2. NO  : Go to Pinpoint Test A .
3. K3 CHECK FOR CORRECT LCM OPERATION 
   • Disconnect all the LCM connectors.
   • Check for:
     • corrosion
     • damaged pins
     • pushed-out pins
   • Connect all the LCM connectors and make sure they seat correctly.
   • Operate the system and verify the concern is still present.
   • Is the concern still present? 
   1. YES  : INSTALL a new LCM. REFER to MULTIFUNCTION ELECTRONIC MODULES article. TEST the system for normal operation.
   2. NO  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
