RKE SYSTEM

When troubleshooting problems with the Remote Keyless Entry System, always verify that the power door lock/unlock switches are functional. If the doors do not lock/unlock with the power switches. the following modules should be analyzed:

^ Lock/Unlock Switches
^ Body Control Module
^ Lock and Unlock Relays
^ Door Lock/Unlock Motors

RKE Block Wiring Diagram:

Refer to Block Wiring Diagram.

If the following modules do not work:

^ Remote keyless entry system
^ Radio/clock
^ Body control module
^ Door lock switches

a blown fuse is the probable cause. The remote keyless entry fuse is located in terminal 13 in the Junction Block. To check for a blown fuse, pull the fuse out slightly, but maintain contact between the fuse terminals and the terminals in Junction Block. Using the voltmeter probe, check both terminals for 12 volts. If only one terminal measures battery voltage, the fuse is defective and must be replaced. If neither terminal measures battery voltage, check for an open or shorted circuit to the Junction Block and repair as needed. If battery voltage is still not available, check the high current fuse G in the Power Distribution Center, located in the engine compartment.
