      Any of the following DTCs are also output. B
      DTC No. Relevant Diagnosis
      P060B-134, 135, 570 Internal Control Module A/D Processing Performance
      P0D53-408 On-Board Charger Output Current Sensor Circuit Low
      P0D54-409 On-Board Charger Output Current Sensor Circuit High

      Tech Tips

      P0D52-407 may be output due to a malfunction which causes the DTCs in the table above to be output. In this case, first troubleshoot the output DTCs in the table above. Then, perform a reproduction test to check that no DTCs are output.

    5. Turn the power switch off.

  2. CHECK ELECTRIC VEHICLE CHARGER ASSEMBLY (ICHG 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.

      Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      z12-24 (ICHG) - 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.
