Check For Intermittent Problems [10/2022 - ]

NOTE:

Vehicle control history (RoB) is stored in the RAM or EEPROM of the certification ECU (smart key ECU assembly). As the cause of a malfunction stored in the RAM will be cleared when the cable is disconnected from the negative (-) auxiliary battery terminal, do not disconnect the cable from the negative (-) auxiliary battery terminal before checking and recording are complete.
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 time 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.

VEHICLE CONTROL HISTORY (ROB)

HINT:

The certification ECU (smart key ECU assembly) stores the vehicle control history (RoB) of the smart access system with push-button start and it can be read using the GTS.

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