Why does Lexus lock the door?

Lexus door locks may have the following aspects:

1. Vehicle collision detection door lock release system is not working properly.

Automatic locking while driving was originally a safety function to prevent the door from suddenly opening during driving. The Lexus LM user manual also points out: "If the vehicle suffers a strong impact, all doors will be unlocked." However, depending on the impact intensity or accident type, the system may not work. The car door lock occurred after the collision of Lexus LM, which was probably caused by the failure of its collision detection door lock release system.

2. The 2.BCM body control module is faulty or damaged.

The BCM body control module of Lexus LM is located near the dashboard of the main driver. Considering the damage to the left front of the vehicle, the airbag bouncing off and the initiative of the main driver after being rescued, it may be that BCM was damaged in the collision and could not receive the signal from the ACU airbag control module normally, resulting in the door not being automatically unlocked after the collision.

3. It is difficult to open the door after the car body is deformed and squeezed.

The collision caused the deformation of the car body structure. You can see that the rear fender has been dented. If the driver has pressed the button to unlock and still can't open the door, it is likely that the car body structure is deformed and the door is stuck.

4. System design defects

Perhaps it is the design defect of the automatic unlocking of the car collision itself. After all, it was an accident. Combined with the news that lexus es's car doors were locked before, people hope that the official can have a clear explanation. After all, the national standard clearly stipulates that the door must be automatically unlocked after a side collision.
