In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.
Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.
The following 5 items are important points for problem analysis:
| What | Vehicle model, system name |
| When | Date, time, occurrence frequency, whether the problem occurred recently or has been occurring for a long time |
| Where | Whether the problem occurs at a specific location |
| Under what conditions? | Whether the doors were locked or unlocked, whether the engine switch was on (IG), whether the engine was running. |
| How did it happen? | Problem symptoms |

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 vehicle control history (RoB) information could be lost.
The vehicle control 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 vehicle control history (RoB). For this reason, before reading the vehicle control vehicle control history (RoB), first make sure that the GTS system clock is accurately set to the current time.
Read and save vehicle control history (RoB) using the GTS.

Measure the auxiliary battery voltage with the ignition switch off.
11 to 14 V
If the voltage is below 11 V, recharge or replace the auxiliary battery before proceeding to the next step.
Check the fuses and relays.
Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.
