Normal Operation

The remote keyless entry (RKE) transmitters and the smart junction box (SJB) 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 SJB every time an RKE transmitter button is pressed.

DTC B2425 - sets when the SJB senses that the key fobs are out of synchronization.
