How to restore the door sensor failure of Haval H2?

[VanClayton]

If the remote key cannot lock the doors, first check if any door is not properly closed. Even one door not fully closed can prevent the doors from locking. If the above situation is ruled out, it is necessary to disassemble and inspect the faulty door to check whether the lock actuator is functioning. If it is not functioning, it is likely that the central control system wiring has poor contact. If the lock actuator is functioning, the issue might be excessive resistance in the locking mechanism, which is usually caused by rust; it could also be due to the displacement of the door lock motor's latch position. Another possible reason is a faulty door lock motor with insufficient pulling force, which would require replacing the motor.
