Center-lock Button

The vehicle can be locked/unlocked with the center-lock button.

If the center-lock button is not being pressed, the junction box electronics module receives a high signal (battery voltage approximately 12 V). The high signal changes to a low signal (approximately 0 V) as soon as the center-lock button is pressed.

The junction box electronics module evaluates the change from the high signal to the low signal and locks/unlocks the vehicle.

In order for locking or unlocking to take place, the driver's door and front passenger door must be closed.
