Remote Keyless Entry (RKE)
The SJB interprets radio frequency signals from the Remote Keyless Entry (RKE) transmitters. The SJB requests the illuminated entry feature to turn the interior lamps on when an unlock command is received. If a lock command is received, the illuminated entry feature turns off.
The RKE transmitter supplies a signal to the SJB when any button is pressed. The SJB then supplies voltage to the appropriate door lock actuator(s) to lock or unlock the doors. The RKE transmitter can also be used to activate the panic alarm. If equipped with a power liftgate, the SJB sends a request to the Liftgate/Trunk Module (LTM) to open or close the power liftgate. On vehicles with memory, the RKE transmitter also causes the SJB to send a Medium Speed Controller Area Network (MS-CAN) message to the Driver Seat Module (DSM) to activate all memory features to the positions associated with the RKE transmitter being used.
