Test Q: The Remote Keyless Entry Transmitter Is Out of Synchronization

PINPOINT TEST Q: THE REMOTE KEYLESS ENTRY TRANSMITTER IS OUT OF SYNCHRONIZATION

Q1-Q4:

Normal Operation
The remote keyless entry (RKE) transmitters and the driver door module (DDM) use a rolling code to prevent the codes from being captured by a code grabber. The system advances the counter in the RKE transmitter and in the DDM every time a RKE transmitter button is pressed.

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

Possible Causes
- aftermarket systems
- high power devices
- TV/radio transmission towers
- RKE transmitter
- DDM
- RKE transmitter button pressed a substantial amount of times while outside the range of the vehicle
