LUGGAGE COMPARTMENT DOOR OPENER SYSTEM Improper Operation

DESCRIPTION

If the luggage compartment door does not open even when the switches are operated, a vehicle malfunction, environmental problem, and customer (including passenger) operation are possible causes. Using History of Reason for Operation allows the cause to be narrowed down, and repair, replacement, and in some circumstances explaining the environment or usage conditions can help resolve the malfunction.

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 out and saved, the operation history information could be lost.

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

        Tech Tips

        Based on the displayed operation history, perform vehicle-side inspection, and perform repairs if a problem is found. If the vehicle has no malfunction, interview the customer about possible causes such as "the driver" and "environmental / other than the driver".
