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

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


G1-G4:






Normal Operation
The remote keyless entry (RKE) transmitter and the vehicle security module 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 vehicle security module every time a RKE transmitter button is pressed.

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

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