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 read out and saved, the 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.
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.
VEHICLE CONTROL HISTORY (RoB)
Vehicle Control History (RoB): The main body ECU (multiplex network body ECU) records the theft deterrent system vehicle control history (RoB), which can be read out using the GTS.
Enter the following menus: Body Electrical / Main Body / Utility / Vehicle Control History (RoB).
