Engine Start/Stop Switch
Pressing the engine start/stop switch changes the vehicle mode to OFF (LOCK), ACCESSORY, ON, or START mode. The engine start/stop switch also includes an LF antenna. When the backup function operating, the engine start/stop switch receives the immobilizer signal from the remote, and sends immobilizer signal to the keyless access/TPMS control unit.
RF (Radio Frequency) Unit
The RF unit is located on the rear shelf. It receives signals from the remote.
LF (Low Frequency) Antennas
The front interior, rear interior, left/right-front, and left/right-rear LF antennas send the signals to the remote inside and outside of the vehicle.
Door Touch Sensors and Outer Handle Lock Switches
The door touch sensors are built in the each door outer handle, also the outer handle lock switches are built in the driver's and front passenger's door outer handles, and rear door outer handles. To operate the door locks without the built-in key while carrying the remote, grip the door outer handle to unlock the doors and press the outer handle lock switch on the door outer handle to lock the doors.
Remote
The remote is equipped with a keyless transmitter and all doors can be locked and unlocked by a lock/unlock button operation even from a remote distance from the vehicle. When the lock button or unlock button is pressed, the keyless transmitter sends the applicable switch signal to the keyless access/TPMS control unit. After receiving authentication from the keyless access/TPMS control unit, the door lock/unlock signals are sent to the MICU through the B-CAN.
