HYBRID BATTERY SYSTEM UTILITY

Note


  • If the HV battery or an HV supply stack sub-assembly has been replaced, make sure to perform the following utilities in the following order: "Battery Diagnosis" then "Battery Status Info Update".

  • "Have Traction Battery Inspected" is displayed, perform "Battery Diagnosis" to diagnose the extent of deterioration of each HV battery cell.

  • "Have Traction Battery Inspected" is cleared after "Battery Diagnosis" are performed and "There is no need to replace HV battery." is displayed.

  • After the "Have Traction Battery Inspected" is displayed, if the traction battery is used continually without performing "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.

  • If the power switch cannot be turned on (READY), perform "Temporary Vehicle Start Up", "Battery Diagnosis".

      Reason for Diagnosis Suspension

      (Related Condition)

      		 Procedure
      The Battery Diagnosis is exiting as it did not complete properly. Discharge the battery until the SOC goes below the threshold value, then perform plug-in charging and execute this function again. Refer to the repair manual for details. SOC (state of charge) learning has not completed.

      1. Lower the SOC (state of charge) of the HV battery by driving the vehicle in EV mode until the mode changes to HV mode.

      2. Make a note of the Data List items from "Hybrid Battery Temperature 1" to "Hybrid Battery Temperature 15".

      3. If the lowest measured battery temperature is 10°C (50°F) or lower, drive the vehicle until the temperature exceeds 15°C (59°F).

        If "Have Traction Battery Inspected" is displayed on the multi-information display and the hybrid vehicle system cannot be started, perform "Temporary Vehicle Start Up" and drive the vehicle.

      4. Perform plug-in charging.

        Note

        Do not use the charging timer function.

      5. After plug-in charging, wait for 35 minutes or more, then turn the power switch on (IG) or on (READY). (Do not turn the power switch on (IG) or on (READY) for at least 35 minutes after plug-in charging. If the vehicle is not fully charged, perform the procedure from step 1 again.)

      6. Leave the vehicle with the power switch on (IG) or on (READY) for 10 minutes or more, turn the power switch off, and then perform battery diagnosis.
      Communication error The power switch was turned off or a GTS communication error occurred.
