POWER DOOR LOCK CONTROL SYSTEM Improper Operation

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.

CAUTION / NOTICE / HINT

Note


  • If the vehicle or vehicle controls are operated (for example, during initial inspection when the vehicle is brought in for repair) before operation history has been read and saved, the operation history information could be lost.

  • The operation history function uses the current system time of the GTS and the time counter inside the controlling ECU to calculate the times shown in the operation history. For this reason, before reading the operation history, first make sure that the GTS system clock is accurately set to the current time.
