    See step  2

  2. DIAGNOSIS 
    1. Confirm with the owner whether or not to perform "Prediagnostic Battery Charge" and "Battery Diagnosis".

      HINT: 

      • It takes about 2 hours to perform "Prediagnostic Battery Charge" and "Battery Diagnosis".
      • Depending on the vehicle usage, it is possible to reuse the HV battery. However, if it is judged not possible to be reused, replace the HV battery.

      Result

      Result Proceed to
      "Prediagnostic Battery Charge" and "Battery Diagnosis" is performed. A
      "Prediagnostic Battery Charge" and "Battery Diagnosis" is not performed. B

    Result: 

    B 

    REPLACE HV BATTERY. Refer to  REMOVAL [11/2021 - ] 

    Result: 

    A 

    See step  3

  3. PERFORM UTILITY (PREDIAGNOSTIC BATTERY CHARGE) 
    1. Apply the parking brake and secure the wheels using chocks.
    2. Perform the "Prediagnostic Battery Charge".

      Refer to UTILITY [11/2021 - ]

      NOTE:
      • If the fuel level warning light is illuminated, add enough fuel that the light turns off, and then perform "Prediagnostic Battery Charge".
      • Perform HV battery charging with appropriate HV battery temperature, between 0°C (32°F) and 47°C (116.6°F).
      • Do not perform prediagnostic battery charge while the master warning is illuminated.
      • Perform prediagnostic battery charge with the HV battery installed correctly.
      • Do not perform prediagnostic battery charge while changing from inspection mode to another mode.

      HINT: 

      • If the HV battery temperature is low (below 0°C (32°F)), drive the vehicle until the temperature reaches 0°C (32°F) or more and perform "Prediagnostic Battery Charge" again.
      • If the HV battery temperature is high (above 47°C (116.6°F)), leave the vehicle with the ignition switch ON (READY) and park (P) selected. Wait until the HV battery temperature drops to 43°C (109.4°F) or lower, and then perform "Prediagnostic Battery Charge" again.
      • If the HV battery temperature is low (below 0°C (32°F)) and the ignition switch cannot be turned to ON (READY), place the vehicle in a warm environment (20°C (68°F) or higher). Wait until the HV battery temperature reaches 0°C (32°F) or higher, and then perform "Prediagnostic Battery Charge" again.

  4. PERFORM UTILITY (BATTERY DIAGNOSIS) 
    1. Perform the "Battery Diagnosis".

      Refer to UTILITY [11/2021 - ]

      NOTE:
      • Perform this diagnosis with the engine coolant at -10°C (14°F) or more.
      • Perform HV battery diagnosis with appropriate HV battery temperature (between 0°C (32°F) and 47°C (116.6°F)).
      • Do not perform battery diagnosis while the master warning is illuminated.
      • Perform battery diagnosis with the HV battery installed correctly.
      • Do not perform battery diagnosis while changing from inspection mode to another mode.
      • The IG off timer function automatically turns the ignition switch off 10 minutes after the battery diagnosis completes. Make sure to confirm the diagnosis result as soon as possible.
      • Make sure to turn the ignition switch off after battery diagnosis to prevent the auxiliary battery from being discharged.
      • If differences among SOCs of each HV battery exceed the specifications, the master warning may illuminate when "Battery Diagnosis" is complete. In this case, check for hybrid system related DTCs. If DTC P3000-16 is output, leave the vehicle with the ignition switch ON (READY) for 10 minutes or more allowing the vehicle to charge the HV battery. Then clear the DTCs.
      • If the vehicle is left with the ignition switch ON after battery diagnosis, the master warning may illuminate. If DTC P3000-00 is output, perform troubleshooting by following the inspection procedure for the DTC.
      • Wait 1 hours or more before turning the ignition switch to ON after the ignition switch is turned off. If the ignition switch is turned to ON shortly after battery diagnosis, the master warning may illuminate.

      HINT: 

      As the "Battery Diagnosis" discharges the HV battery to a low SOC, if the ignition switch is turned to ON immediately after the "Battery Diagnosis" is completed, DTC P31AB-16 (Hybrid Battery Cell Low Voltage) may be stored. For this reason, leave the vehicle as is for 1 hours to allow the HV battery SOC to recover.

    2. Check the battery diagnosis result.

      Result

      Result Proceed to
      OK ("There is no need to replace HV battery.") A
      NG (Replace the listed No. 1 HV supply stack sub-assembly) B
      NG (Replace the listed No. 2 HV supply stack sub-assembly) C

    Result: 

    B 

    REPLACE NO. 1 HV SUPPLY STACK SUB-ASSEMBLY. Refer to  REMOVAL [11/2021 - ] 

    Result: 

    C 

    REPLACE NO. 2 HV SUPPLY STACK SUB-ASSEMBLY. Refer to  REMOVAL [11/2021 - ] 

    Result: 

    A 

    See step  5

  5. CHARGE HV BATTERY 
    1. Turn the ignition switch to ON (READY).

      HINT: 

      • Charge the HV battery with the ignition switch ON (READY) to recover the SOC after "Battery Diagnosis".
      • The READY indicator illuminates and the engine starts.
    2. Leave the vehicle with the shift lever in P until the engine stops.

      HINT: 

      The engine stops when the SOC of the HV battery reaches the specified amount.

    3. Turn the ignition switch off.
