Test M: The Remote Keyless Entry (RKE) Transmitter Is Out Of Synchronization

PINPOINT TEST M: THE REMOTE KEYLESS ENTRY (RKE) TRANSMITTER IS OUT OF SYNCHRONIZATION

Normal Operation
The RKE transmitter 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.

DTC B2425 (Remote Keyless Entry Out of Synchronization) - is a continuous DTC that sets when the DDM detects that the rolling codes are out of synch.

This pinpoint test is intended to diagnose the following:
- RKE transmitter button pressed a substantial amount of times outside the range of the vehicle
- RKE transmitter
