HYBRID BATTERY SYSTEM "HAVE TRACTION BATTERY INSPECTED" is displayed

DESCRIPTION

The hybrid vehicle control ECU monitors the SOC (state of charge) of the HV battery. When it finds the HV battery has deteriorated excessively, it will display "HAVE TRACTION BATTERY INSPECTED" on the multi-information display. If "HAVE TRACTION BATTERY INSPECTED" is displayed, perform "Battery Diagnosis" and replace the HV battery as necessary.

CAUTION / NOTICE / HINT

CAUTION:


  • When disposing of an HV battery, make sure to return it through an authorized collection agent who is capable of handling it safely. If the HV battery is returned via the manufacturer specified route, it will be returned properly and in a safe manner by an authorized collection agent.

  • Before returning the HV battery, make sure to perform a recovery inspection Click here

  • Make a note of the output DTCs as some of them may be necessary for recovery inspection of the HV battery.

Note


  • After "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.

    *:The timing may vary depending on vehicle usage.

  • "HAVE TRACTION BATTERY INSPECTED" is cleared when both of the following conditions are met:


    1. "Prediagnostic Battery Charge" and "Battery Diagnosis" have been performed.

    2. "003" (There is no need to replace HV battery) is displayed on the GTS.

  3. DIAGNOSIS


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

      Tech Tips


      • It takes about 6 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

  4. Utility (Prediagnostic Battery Charge)


    1. Apply the parking brake and secure the wheels using chocks.

    2. Perform "Prediagnostic Battery Charge" Click here.

      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 10°C (50°F) and 55°C (131°F).

      • Do not perform prediagnostic battery charge while the master warning light 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.

      Tech Tips


      • If the HV battery temperature is low (below 10°C (50°F)), drive the vehicle until the temperature reaches 10°C (50°F) or more) and perform "Prediagnostic Battery Charge" again.

      • If the HV battery temperature is high (above 55°C (131°F)), leave the vehicle with the power switch on (READY) and park (P) selected. Wait until the HV battery temperature drops to 50°C (122°F) or lower, and then perform "Prediagnostic Battery Charge" again.

      • If the HV battery temperature is low (below 10°C (50°F)) and the power switch cannot be turned on (READY), place the vehicle in a warm environment (20°C (68°F) or higher). Wait until the HV battery temperature reaches 10°C (50°F) or higher, and then perform "Prediagnostic Battery Charge" again.

  5. Utility (Battery Diagnosis)


    1. Perform "Battery Diagnosis" Click here.

      Note


      • Perform this diagnosis with the engine coolant at -10°C (-50°F) or more.

      • Perform HV battery diagnosis with appropriate HV battery temperature, between 10°C (50°F) and 55°C (131°F).

      • Do not perform battery diagnosis while the master warning light 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 power switch off one hour after the battery diagnosis completes. Make sure to confirm the diagnosis result as soon as possible.

      • Make sure to turn the power 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 light may illuminate when "Battery Diagnosis" is complete. In this case, check for hybrid system related DTCs. If DTC P3000-389 is output, leave the vehicle with the power 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 power switch on (IG) after battery diagnosis, the master warning light may illuminate. If DTC P3000-388 is output, perform troubleshooting by following the inspection procedure for the DTC.

      • Wait 5 hours or more before turning the power switch on (IG) after the power switch is turned off. If the power switch is turned on (IG) shortly after battery diagnosis, the master warning light may illuminate.

      Tech Tips

      As the "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 P31AB-123 (Hybrid Battery Cell Low Voltage) may be stored. For this reason, leave the vehicle as is for 5 hours to allow the HV battery SOC to recover.

    2. Check the battery diagnosis result.

  6. CHARGE HV BATTERY


    1. Turn the power switch on (READY).

      Tech Tips


      • Charge the HV battery with the power switch on (READY) to recover the SOC after "Battery Diagnosis".

      • The READY indicator illuminates and the engine starts.

    2. Leave the vehicle with park (P) selected until the engine stops.

      Tech Tips

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

    3. Turn the power switch off.
