WIPER AND WASHER SYSTEM CHECK FOR INTERMITTENT PROBLEMS

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.

  • The time counter in the control ECU may deviate by up to +/- 10% due to the characteristics of the time counter.

  • The time counter in the control ECU is reset approximately 34 days before the "Current" value due to the characteristics of the time counter. Therefore, the time information stored before the 34th day may not be accurately displayed.
