Diagnosis And Testing-Power Locks
When trouble shooting problems with the Remote Keyless Entry System, always verify that the power door lock/unlock witches are functional. If the doors do not lock/unlock with the power switches, the following components should be analyzed:
- Door Lock Switches
- Body Control Module
- Lock and unlock relays
- Door lock/unlock motors
- Remote keyless entry system
- Radio/clock
A blown fuse is the portable cause. The remote keyless entry fuse 13 is located in the Junction Block If neither terminal measures battery voltage, check for an open or shorted circuit to the Junction Block, 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.
To diagnose the Remote Keyless Entry (RKE) System, use a DRBIII(R) scan tool and refer to Power Door Lock System in BODY DIAGNOSTIC PROCEDURES .
