Test J: The Remote Keyless Entry (RKE) Transmitter Is Inoperative
PINPOINT TEST J: THE REMOTE KEYLESS ENTRY (RKE) TRANSMITTER IS INOPERATIVENormal Operation
Remote locking and unlocking of the doors is accomplished by the smart junction box (SJB) receiving a command message from the RKE transmitter. The SJB energizes the appropriate relays to lock or unlock the doors. The RKE transmitters and SJB also utilize a rolling code to prevent the code from being "captured" by a code grabber. The system advances the counter in the RKE transmitter and SJB every time an RKE transmitter button is pressed.
- DTC B2425 (Remote Keyless Entry Out of Synchronization) - is a continuous DTC that sets when the SJB detects the rolling counter received from an RKE transmitter is 1,024 times greater than the rolling counter stored in the module.
This pinpoint test is intended to diagnose the following:
- RKE transmitter
- RKE transmitter battery
- RKE transmitter button pressed a substantial amount of times while outside the range of the vehicle
- RKE transmitter programming
- SJB
