Info Added 2017-10-06

DTC Code DTC Name
P1CE213 PCU Interlock Circuit Open
P1CE292 PCU Interlock Performance or Incorrect Operation

DTC SUMMARY


  1. MALFUNCTION DESCRIPTION

    The hybrid vehicle control ECU detects that a safety device (interlock) is operated or that there is an open circuit in the detection circuit. (Even if an open circuit occurs while the vehicle is stopped, the system determines that the safety device was operated.)

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


      Detection switch system malfunction

    • Inverter with converter assembly malfunction


      Low-voltage system malfunction

    • Motor generator control ECU (MG ECU) malfunction

    • Inverter with converter assembly malfunction

    • CAN communication error between the MG ECU and hybrid vehicle control ECU

  2. INSPECTION DESCRIPTION

    A005MO2E05
    System Diagram Location Inspection Content Reason Inspection Step
    *a Check whether the safety device (interlock) is connected securely and installed properly (inverter cover, etc.). DTC output due to improper connection or forgetting to install parts. 4
    *b Inspect the detection circuit. DTC output due to an open circuit or improper connection (dirt, foreign matter, etc.). 5

CONFIRMATION DRIVING PATTERN

Tech Tips

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

Click here


  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. With power switch on (IG) and wait for 5 seconds or more.

  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

CAUTION:


  • B0048QQ

    Before the following operations are conducted, take precautions to prevent electric shock by turning the power switch off, wearing insulated gloves, and removing the service plug grip from HV battery.


    • Inspecting the high-voltage system

    • Disconnecting the low voltage connector of the inverter with converter assembly

    • Disconnecting the low voltage connector of the HV battery


  • A005NJP

    To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.


  • A005NAH

    After removing the service plug grip from the HV battery, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.


  • B0048M5C01
    *a Without waiting for 10 minutes

    After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.

    Tech Tips

    Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.

Note


  • After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

  • 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.

  • As interlock circuit DTCs or other DTCs may be stored when the power switch is turned on (IG) in the following procedure, make sure to clear the DTCs after inspection.
