Function Test

• Lock and unlock the car a few times.
  NOTE: If locking and unlocking is performed too many times in succession, the lock motors can become hot. The lock motors will stop working temporarily. During the check, the locks should therefore not be locked or unlocked more than 10 times in succession without the motors being given time to cool (approximately 30 seconds).

  The car can be locked or unlocked using the central locking button or the remote control.

  Check that the door locks/unlocks.

  Also check that the lock unit is activated twice for every locking/unlocking.

  The door must be locked/unlocked and the lock motor may only be activated once per locking/unlocking.
