  3. READ AND SAVE VEHICLE CONTROL HISTORY (ROB) 
    NOTE:
    • 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 and saved, the vehicle control history (RoB) information could be lost.
    • The vehicle control history (RoB) function uses the current system time of the GTS and the time counter inside the controlling ECU to calculate the times shown in the vehicle control history (RoB). For this reason, before reading the vehicle control history (RoB), first make sure that the GTS system clock is accurately set to the current time.
    1. Read and save vehicle control history (RoB) using the GTS.
