Operation Check
- CHECK SMART KEY SYSTEM (for Entry Function) OPERATION NOTE:
Make sure that the smart key system (for Entry Function) has not been canceled before performing this inspection.
- Check the entry unlock function (driver side door, front passenger side door).
- Perform a wireless lock operation to lock all the doors, touch the unlock sensor built into the backside of the front door outside handle assembly of the driver side door while carrying the electrical key transmitter and check that all the doors unlock.
HINT:
To perform a wireless lock operation, press the lock switch of the electrical key transmitter while standing near the front door outside handle assembly.
- Inspect the entry unlock detection area. Hold the electrical key transmitter at the same height as the front door outside handle assembly (approximately 0.8 m (2.62 ft.) from the ground) and approximately 0.7 m (2.30 ft.) from the vehicle as shown in the illustration and check that the LED (red) of the electrical key transmitter blinks.
