Improper Operation [06/2018 - ]: Description

In cases where the doors locked or unlocked by themselves even though a door lock or unlock operation was not performed, a vehicle malfunction, accidental operation by the customer or a passenger, or environmental factors should all be considered as a possible cause. By using the operation history, the possible causes of the malfunction can be narrowed down, enabling the problem to be solved by repair or replacement, or by explaining to the customer how environmental factors affect the operation.
