HYBRID BATTERY SYSTEM UTILITY

Note

If the HV battery is replaced, make sure to perform both "Prediagnostic Battery Charge" and "Battery Diagnosis".
Make sure to perform "Prediagnostic Battery Charge" before "Battery Diagnosis".
If the hybrid battery indicator light comes on or "HAVE TRACTION BATTERY INSPECTED" is displayed, perform both "Prediagnostic Battery Charge" and "Battery Diagnosis" to diagnose the extent of deterioration of each HV battery.
The hybrid battery indicator turns off or "HAVE TRACTION BATTERY INSPECTED" is cleared after both "Prediagnostic Battery Charge" and "Battery Diagnosis" are performed and "There is no need to replace HV battery." is displayed.
After the hybrid battery indicator light turns on or "HAVE TRACTION BATTERY INSPECTED" is displayed, if the traction battery is used continually without performing "Prediagnostic Battery Charge" and "Battery Diagnosis" for a few weeks*, use of the HV battery (input/output voltage) will be limited. If it is used more, the power switch on (READY) operation will be disabled.

*: Timing may vary depending on vehicle usage.

To prevent the auxiliary battery from being depleted, make sure to turn the air conditioning system related switches, headlight dimmer switch and power switch off as soon as "Battery Diagnosis" is complete.

Tech Tips

As "Battery Diagnosis" discharges the HV battery to a low SOC, if the power switch is turned on immediately after the "Battery Diagnosis" is completed, DTC P3000-388 or P3000-389 may be stored. For this reason, leave the vehicle as is for 5 hours to allow the HV battery SOC to recover or charge the HV battery using the THS Charger. Then, clear the DTCs and check that no DTCs are output. If DTC P3000-388 or P3000-389 is output again, perform troubleshooting for the DTC.

Press "Exit" and turn the power switch off.

Tech Tips

If the diagnosis result is "Replace the HV battery", replace the HV battery.
