CHECK FOR INTERMITTENT PROBLEMS

NOTICE:

If the vehicle or vehicle controls are operated (for example, during initial inspection when the vehicle is brought in for repair) before Vehicle Control History (RoB) has been collected, the past Vehicle Control History (RoB) information could be lost.
The function "Read Vehicle Control History (RoB)" uses the current system time setting inside the GTS and the time counter inside the controlling ECU to calculate the timings shown in the Vehicle Control History (RoB). For this reason, before reading out the Vehicle Control History (RoB), first make sure that the GTS system clock is accurately set to the current time.
Due to the characteristics of the time counter inside the controlling ECU, the value may be off by up to 10%.
Due to its characteristics, the time counter inside the controlling ECU is retroactively reset approximately 34 days before the current time point. For this reason, time information recorded 34 days or more before the current time point may not be accurately displayed.

HINT:

The main body ECU (multiplex network body ECU) stores Vehicle Control History (RoB) for the power window system, which can be read using the GTS.

VEHICLE CONTROL HISTORY (RoB)

(a) Check the Vehicle Control History (RoB) according to the display on the GTS.
