CUSTOMER PROBLEM ANALYSIS |
HINT:
- 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:
*: Interview the customer about the details of the driving conditions, environment and the malfunction, then check the DTCs after reading and storing the record of behavior. 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?
Driving conditions, weather conditions
How did it happen?

READ AND SAVE VEHICLE CONTROL HISTORY (RoB)* |
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 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.
(a) Read and save vehicle control history (RoB) using the GTS.

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