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:

  What	Vehicle model, system name
  When	Date, time, occurrence frequency
  Where	Road conditions
  Under what conditions?	Driving conditions, weather conditions
  How did it happen?	Problem symptoms

1. Using the Techstream, check for Vehicle Control History (RoB).

   Body Electrical > Main Body > Utility 

   Tester Display
   Vehicle Control History (RoB)

2. Make a note of the Vehicle Control History (RoB) output.

   Result

   Result	Proceed to
   Vehicle Control History (RoB) is not output	A
   Vehicle Control History (RoB) is output	B

Result: 

B 

GO TO VEHICLE CONTROL HISTORY (RoB) 

Refer to VEHICLE CONTROL HISTORY (RoB) [10/2023 - ]

See step  4

1. Measure the auxiliary battery voltage with the ignition switch off.

   Standard voltage

   11 to 14 V

   HINT: 

   • A simple method to determine whether the auxiliary battery is discharged is to operate the horn.
   • If the voltage is below 11 V, recharge or replace the auxiliary battery before proceeding.
2. Check the fuses and relays.
3. Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.
