PLUG-IN CHARGE CONTROL SYSTEM, Diagnostic DTC:P1C1D00

DTC Code DTC Name
P1C1D00 Charging Power Low

DTC SUMMARY


  1. MALFUNCTION DESCRIPTION

    The charge control ECU built into the electric vehicle charger assembly monitors its internal operation. If it detects a power output malfunction in the electric vehicle charger assembly, it stores a DTC. If this DTC is output, check the plug-in charge state using a known good external power source. If a malfunction occurs again, replace the electric vehicle charger assembly.

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


      Malfunction in the vehicle side

    • Electric vehicle charger assembly malfunction


      Malfunction except vehicle side

    • External power source malfunction

  2. INSPECTION DESCRIPTION

  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. Enter the following menus: Powertrain / Hybrid Control / Data List.

  5. Check that "Hybrid Battery SOC" shows 70% or less.

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

  7. Connect the electric vehicle charger cable assembly, and plug-in charge the vehicle for 30 seconds or more.

  8. Disconnect the electric vehicle charger cable assembly and wait for 10 seconds or more.

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

  10. Enter the following menus: Powertrain / Plug-in Control / Utility / All Readiness.

  11. 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 PLUG-IN CHARGE STATE

    Result
    Result Proceed to
    DTCs are not output and plug-in charge has been completed. A
    DTCs are output or plug-in charge cannot be completed. B

    Tech Tips


    • Ask the customer if the electricity used for plug-in charging was supplied by a power company.

    • If the electric vehicle charger cable assembly that was used to perform plug-in charging is available, perform a reproduction test using it and a known good AC power source. This allows the electric vehicle charger cable assembly to be determined as ok or not when the vehicle is not malfunctioning.

    • This DTC may be output due to rapid fluctuation of the AC input voltage.

    • If the voltage fluctuates quickly, it is difficult to check the plug-in charge state by reading the freeze frame data or Data List item "AC Input Voltage for Monitoring" and "AC Input Voltage for Control".


    1. Perform plug-in charging using a known good AC power source.


      1. Connect the GTS to the DLC3.

      2. Turn the power switch on (IG).

      3. Clear the DTCs.


        Powertrain > Plug-in Control > Clear DTCs

      4. Enter the following menus: Powertrain / Hybrid Control / Data List.

      5. Check that "Hybrid Battery SOC" shows 70% or less.


        Powertrain > Hybrid Control > Data List
        Tester Display
        Hybrid Battery SOC

      6. Turn the power switch off.

      7. Connect the charging cable (electric vehicle charger cable assembly) and fully charge the HV battery, then check if plug-in charge control system DTCs are output.

        Note

        Perform plug-in charging using a known good AC power source.
