INSPECTION PROCEDURE

1.CHECK DTC OUTPUT (HV)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the power switch on (IG).

  1. Enter the following menus: Powertrain / Hybrid Control / DTC.

  1. Check if DTCs are output.

    Result:

    		Proceed to
    P0A72 or P0A75 only is output.
    		A
    P0A7A-203 is output.
    		B

  1. Turn the power switch off.

2.CHECK CONNECTOR CONNECTION CONDITION (INVERTER WITH CONVERTER ASSEMBLY CONNECTOR)
A214648

CAUTION:
Be sure to wear insulated gloves.

  1. Check that the service plug grip is not installed.

    NOTICE:
    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.

NOTICE:
Before disconnecting the connector, confirm that it is properly connected by checking that the locking claws are engaged and that the connector does not pull out.

  1. Check the connection of the low voltage connector of the inverter with converter assembly.

    OK:
    The connector is connected securely and there are no contact problems.

    HINT:
    When connecting the connector, insert it with the locking lever in the raised position. Rotate the lever downward and make sure that the connector is pulled into its socket. When the locking lever is in its fully closed position, a click will be heard as its locking claws engage. After the click is heard, pull up on the connector to confirm that it is properly connected.
