Test M1:






Test M2-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 remote transmitter. The RKE module processes the command and sends a signal directly to the door lock actuators. The remote transmitter has a minimum operating range of 10 m (33 feet).

All remote 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
- remote transmitter
- RKE module
