HYBRID CONTROL SYSTEM, Diagnostic DTC:P0ABF00

DTC Code DTC Name
P0ABF00 Hybrid/EV Battery Current Sensor "A" Circuit Range/Performance

DESCRIPTION

A battery current sensor is installed to the positive (+) terminal side of the HV battery and detects current flowing from the HV battery. The battery current sensor outputs voltage, which changes between 0 and 5 V according to the detected amperage, to the IB terminal of the battery voltage sensor. The battery voltage sensor sends signals to the hybrid vehicle control ECU. The hybrid vehicle control ECU determines the charging and discharging amount of the HV battery based on the received signals and calculates the SOC of the HV battery through the accumulated amperage.

  1. Connect the GTS to the DLC3.

  2. Turn the power switch on (IG) and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the power switch off and wait for 2 minutes or more.

  5. Turn the power switch on (IG) and turn the GTS on.

  6. Drive the vehicle for approximately 10 minutes according to the freeze frame data items "Vehicle Speed", "Accelerator Position", "Hybrid Battery Current", "Motor Torque" and "Generator Torque".

  7. Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.

  8. Check the DTC judgment result.

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform driving pattern again.

PROCEDURE


  1. CHECK DTC OUTPUT (HYBRID CONTROL)

    CAUTION:

    Be sure to wear insulated gloves.


    1. Check that the service plug grip is not installed.

      Note

      After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction.

    2. Remove the No. 1 HV battery cover panel RH.

      z12-6 (VIB) or z13-1 (VIB) - Body ground and other terminals Power switch off 10 kΩ or higher

      Tech Tips

      As the battery harness is not available as a supply part, if the harness cannot be repaired, replace the HV battery.

    7. Reconnect the battery voltage sensor connector.

    8. Install the No. 1 hybrid battery exhaust duct.

    9. Reconnect the battery current sensor connector to the HV battery junction block assembly.

    10. Install the No. 1 HV battery cover panel RH.
