1. If the duration of the sensor wire break is more than 200 ms, a buzzer sound is heard for 5 s. When the malfunction is eliminated, the emergency lock opening system should not work.

2. If the sensor circuit is short-circuited and it works for more than 2 seconds, after the operation of the lock opening system in emergency mode for 3 seconds, a buzzer sound is heard for 5 seconds. When the malfunction is eliminated, the emergency lock opening system should not work.

3. Check up resistance between conclusions of a socket of the gauge.
