HYBRID CONTROL SYSTEM, Diagnostic DTC:P1AC413

DTC Code DTC Name
P1AC413 Hybrid/EV Battery Stack 1 Current Interrupt Device Circuit Open

DTC SUMMARY


  1. MALFUNCTION DESCRIPTION

    Current interrupt devices (CIDs), which mechanically shut off the high-voltage circuit, are installed in each HV battery cell to protect the HV battery from overcharge (overvoltage).

    The cause of this malfunction may be one of the following:


      HV Battery Assembly internal malfunction

    • Battery ECU Assembly malfunction

DESCRIPTION

The hybrid vehicle control ECU detects a shut-off by a CID in a HV battery cell.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Warning Indicate
P1AC413 Hybrid/EV Battery Stack 1 Current Interrupt Device Circuit Open

The hybrid vehicle control ECU detects that a CID has operated in the HV battery.

When the power switch is on (READY), the hybrid vehicle control ECU receives a signal indicating a drop in cell voltage from the battery ECU assembly due to the voltage before boosting being out of the normal range or the cumulative change in voltage before boosting is large for a certain amount of time.

Tech Tips

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

  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. Turn the power switch on (READY) and wait for 3 minutes or more.

    Tech Tips

    According to the display on the GTS, read the Data List and monitor the values of "Hybrid Battery Voltage" and "VL-Voltage before Boosting" for 3 minutes. If the difference between "Hybrid Battery Voltage" and "VL-Voltage before Boosting" is always less than 50 V, the vehicle has returned to normal.

  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.

CAUTION / NOTICE / HINT

Note

If the DTCs are cleared or the cable is disconnected and reconnected to the negative (-) auxiliary battery terminal before performing repairs, turning the power switch on (READY) may cause a malfunction. Do not turn the power switch on (READY).

PROCEDURE


  1. CHECK DTC OUTPUT (HV BATTERY)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

      Note

      If the DTCs are cleared or the cable is disconnected and reconnected to the negative (-) auxiliary battery terminal before performing repairs, turning the power switch on (READY) may cause a malfunction. Do not turn the power switch on (READY).

    3. Enter the following menus: Powertrain / Hybrid Control and HV Battery / Trouble Codes.

    4. Check for DTCs.
