Normal Operation
Remote locking and unlocking of the doors is accomplished by the smart junction box (SJB) receiving a command message from the RKE transmitter. The SJB processes the command and provides voltage and ground to the door lock actuators. The RKE transmitter has a minimum effective operating range of 10 m (33 feet).
All RKE transmitters must be present to begin diagnosis of the RKE system.
Aftermarket or dealer-installed systems may adversely affect the RKE system operation. These systems should be disconnected before diagnosing any RKE concerns.
Possible Causes
- aftermarket systems
- high power devices
- TV/radio transmission towers
- RKE transmitter
- SJB
