D10:






Normal Operation
Remote locking and unlocking of the doors is accomplished by the smart junction box (SJB) receiving a command message from the remote keyless entry (RKE) transmitter. The SJB processes the command and provides voltage and ground to the door lock actuators.

All RKE transmitters must be present to begin diagnosis of the RKE system.

Aftermarket or dealer-installed systems may adversely effect the RKE system operation. These systems should be disconnected before diagnosing any RKE concerns.

Possible Causes
- RKE transmitter battery
- RKE transmitter programming
- RKE transmitter
- aftermarket systems
- high power devices
- TV/radio transmission towers
- SJB
