Keyless Access System Description - Control/Function (2016-17)
Smart Entry Function
The keyless access/TPMS control unit detects the input signal of the door outer handle touch sensors, the door lock switches, tailgate outer handle switch, the tailgate lock switch, and authenticates 2-way communication with the remote. The keyless access/TPMS control unit then sends a door lock signal, door unlock signal, and an answer back signal to the MICU via B-CAN line.
Keyless Entry Function
The keyless access/TPMS control unit receives the keyless transmitter signal from the remote. The keyless access/TPMS control unit authenticates the RF signal, and sends a door lock/unlock signal to the MICU via the B-CAN.
Backup Communication Function
The keyless access system has a backup communication feature: If the remote battery goes dead, touch the remote to the engine start/stop switch on the dashboard. The remote transponder then receives an immobilizer code from the engine start/atop switch, allowing you to start the vehicle.
Key Lockout Prevent Function
The lockout prevent function observes the key switch signal input. If the input is "ON" (remote in the vehicle), the system will not lock the doors. If the driver manually locks and closes the doors or tailgate with a remote is in the vehicle (input ON), the MICU energizes the driver's door lock actuator and unlocks the driver's door.
Fault Diagnosis Function
The system has a fault diagnosis function. If any malfunction occurs, the keyless access indicator comes on in the gauge control module.
Panic Function
When you press and hold the PANIC button on the remote, the keyless access/TPMS control unit sends a signal to the MICU via the B-CAN to sound the horn and activate the exterior lights.
Remote Search Function
Determines if the remote is present inside the vehicle during some operation or function.Detects the door open or close when the vehicle in the ACCESSORY/ON mode. When the remote is taken out of the vehicle, the outside buzzer will sound and the multi-information display (MID) (Only when the vehicle in the ON mode) will show a warning.
Electric Steering Lock (With Electric Steering Lock)
The electric steering lock control unit is built into the electric steering lock, and it controls the steering lock motor. When the remote code is identified, the electric steering lock control unit unlocks the steering lock by controlling the steering lock motor.
Lighting and indicator Function
The keyless access/TPMS control unit controls the engine start/stop switch indicator, displays information in the multi-information display (MID), and illuminates the keyless access indicators in the gauge control module.
Registration Facility
The keyless access/TPMS control unit can store up to 6 remotes with the HDS.
Client Emergency
If for any reason you need to shut off the engine while the vehicle is in motion, press the engine start/stop button quickly 2 times, or hold the engine start/stop button for 1.5 seconds. The engine turns off, and the vehicle mode switches to ACCESSORY. In this mode, the steering wheel remains unlocked.
Remote Engine Start System (With Remote Engine Start)
Start the Engine
The remote engine start feature is initiated by first pressing the lock button, then pressing and holding the "START" button within 5 seconds on the remote transmitter. An RF signal from the remote transmitter is received by the 2-way transceiver antenna, sent to the 2-way transceiver, which sends it to the keyless access/TPMS control unit, which then sends the request to start the engine to the PCM. At the same time, the keyless access/TPMS control unit authenticates the key for the immobilizer system. The PCM starts the engine and sends feedback to the keyless access/TPMS control unit indicating the status of the engine. The keyless access/TPMS control unit disables the headlights and windshield wipers via the B-CAN and an IG1 REM signal to the MICU. The keyless access/TPMS control unit also disables the power windows, door locks and the gauge control module illumination by sending a signal over the B-CAN to all related control units.
Answer Back
The bi-directional remote transmitter uses 3 LEDs to provide feedback for remote engine starting. This feedback enables users to confirm the bi-directional remote transmitter button presses, whether the engine started or not, and whether the doors locked.
