Test G: The Remote Keyless Entry (RKE) Transmitter Is Inoperative
PINPOINT TEST G: THE REMOTE KEYLESS ENTRY (RKE) TRANSMITTER IS INOPERATIVENormal Operation
Remote locking and unlocking of the doors, activating the panic alarm, and releasing the luggage compartment lid latch is accomplished by the smart junction box (SJB) receiving a command message from the remote keyless entry (RKE) transmitter. The SJB processes the command and provides the appropriate output. 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
