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

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

D1-D4:

Normal Operation
The RKE transmitters 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 an RKE transmitter button is pressed.

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

Possible Causes
- RKE transmitter button is pressed a substantial amount of times while outside the range of the vehicle
- RKE transmitter
- vehicle security module
