PINPOINT TEST H: THE REMOTE KEYLESS ENTRY (RKE) TRANSMITTER HAS POOR RANGE PERFORMANCEH1-H2:
H3-H5:
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 through the SJB external antenna. The SJB processes the command and sends a signal directly to the door lock actuators. The RKE transmitter has a minimum operating range of 10 m (33 ft).
All RKE transmitters need to 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
- RKE transmitter
- SJB external antenna
- Aftermarket systems
- High power devices
- TV/radio transmission towers
- SJB
