Result:
B
GO TO DTC CHART (HYBRID BATTERY SYSTEM). Refer to DIAGNOSTIC TROUBLE CODE CHART [09/2022 - ]
Result:
C
GO TO DTC CHART (HYBRID CONTROL SYSTEM). Refer to DIAGNOSTIC TROUBLE CODE CHART [09/2022 - ]
Result:
A
See step 2
- Check for DTCs.
- CHECK TOTAL DISTANCE DRIVEN
- Read the odometer to check the total distance the vehicle has been driven.
Result
Result Proceed to Total distance driven is less than 200000 km (124280 mile) A Total distance driven is 200000 km (124280 mile) or more Current total distance driven - total distance driven when HV battery junction block assembly replaced = less than 200000 km (124280 mile) *1 Other than above B HINT:
*1: If the HV battery junction block assembly has been replaced, use the total distance driven since it was replaced.
Result:
A
REPLACE HV BATTERY. Refer to REMOVAL [09/2022 - ]
