HYBRID CONTROL SYSTEM, Diagnostic DTC:P0D4C1C

DTC Code DTC Name
P0D4C1C Hybrid/EV Battery Charger Hybrid/EV Battery Input Voltage Sensor Voltage Out of Range

DTC SUMMARY


  1. MALFUNCTION DESCRIPTION

    The charging voltage sensor (VCHG) built into the electric vehicle charger assembly detects the output voltage of the high-voltage DC circuit of the electric vehicle charger assembly. This information is output to the hybrid vehicle control ECU which compares the charging voltage (VCHG) with the HV battery voltage (VB). If the difference between them is large, the hybrid vehicle control ECU detects a malfunction.

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


      Electric vehicle charger assembly VCHG sensor internal circuit malfunction

    • Electric vehicle charger assembly malfunction


      Battery ECU assembly VB sensor internal circuit malfunction

    • Battery ECU assembly malfunction

DESCRIPTION

The electric vehicle charger assembly sends charging voltage sensor signals to the hybrid vehicle control ECU via CAN communication.

  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, 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 / Hybrid 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.
