PLUG-IN CHARGE CONTROL SYSTEM, Diagnostic DTC:P0D4D-404

DTC Code DTC Name
P0D4D-404 On-Board Charger Output Voltage Sensor Circuit Range / Performance

DESCRIPTION

A VCHG sensor (DC output voltage sensor) is located inside the electric vehicle charger assembly. It detects output voltage to the DC high-voltage circuit and sends a signal to the plugin charge control ECU assembly. The plugin charge control ECU assembly monitors and detects errors in the VCHG sensor signal line.

The plugin charge control ECU assembly detects output power of the electric vehicle charger assembly based on signals from the VCHG sensor. At the same time, fusing of charge relay contacts is detected.

This DTC may also be stored if a short or open occurs in the high-voltage circuit (between the HV battery and electric vehicle charger assembly), or if the CHRG relay is stuck open. (In this case, DTC P02D0-422 (Charger Relay Stuck Open) is stored the next time plug-in charging is performed.)

INSPECTION PROCEDURE

Tech Tips

After the repair, check that the Data List item "State of Charge (All Bat)" is 70% or less, then plug-in charge the vehicle for 20 seconds or more and check that DTCs are not output.

PROCEDURE


  1. CHECK DTC OUTPUT (HYBRID CONTROL)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

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

    4. Check if DTCs are output.

      P31AB-123 Hybrid Battery Cell Low Voltage

      Tech Tips

      P0D4D-404 may be set due to a malfunction which also causes DTCs in the preceding table to be set. In this case, first troubleshoot the output DTCs in the preceding table. Then, perform a test to attempt to reproduce the problems, and check that no DTCs are output.

    5. Turn the power switch off.

  4. CHECK ELECTRIC VEHICLE CHARGER ASSEMBLY (VCHG SENSOR OUTPUT VOLTAGE)

    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. Disconnect the z12 plugin charge control ECU assembly connector.

    3. Connect the cable to the negative (-) auxiliary battery terminal.

    4. Turn the power switch on (IG).

      z12-25 (VCHG) - z12-21 (CGND) Power switch on (IG) 1.5 to 2.5 V

      Tech Tips

      Turning the power switch on (IG) with the plugin charge control ECU assembly connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

    6. Turn the power switch off.

    7. Disconnect the cable from the negative (-) auxiliary battery terminal.

    8. Reconnect the z12 plugin charge control ECU assembly connector.
