Test M: The Remote Keyless Entry Transmitter Has Poor Range Performance

PINPOINT TEST M: THE REMOTE KEYLESS ENTRY TRANSMITTER HAS POOR RANGE PERFORMANCE


M1-M2:






M3-M4:






Normal Operation
Remote locking and unlocking of the doors is accomplished by the remote keyless entry (RKE) module receiving a command message from the RKE transmitter. The RKE module 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 feet).

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

Aftermarket or dealer-installed system 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
- RKE module
