• When troubleshooting, check 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. For HV Model
   1. Measure the auxiliary battery voltage with the ignition switch off.

      Standard Voltage

      11 to 14 V

      HINT: 

      If the voltage is below 11 V, recharge or replace the auxiliary battery before proceeding to the next step.

2. For Gasoline Model
   1. Measure the auxiliary battery voltage.

      Standard Voltage

      11 to 14 V

      HINT: 

      If the voltage is below 11 V, recharge or replace the auxiliary battery before proceeding to the next step.

1. Recheck for DTCs.

   Body Electrical > D-SEAT SW > Trouble Codes 

   Result

   Result	Proceed to
   DTCs are output.	A
   DTCs are not output.	B

   HINT: 

   • Even if the problem symptom is not confirmed, check for DTCs. This is because the system stores history DTCs.
   • If more information is needed, perform a recheck using the "System Check Mode" screen after rechecking for DTCs using the GTS.
   • Check for DTCs and inspect the area that the code indicates.
