   NOTE:

   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.

   OK

   The connectors are connected securely and there are no contact pressure 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.

NG → CONNECT SECURELY 

OK: Go to next step 

1. Check the connector connections and contact pressure of the relevant terminals for the power management control ECU connectors. Refer to ELECTRONIC CIRCUIT INSPECTION PROCEDURE [08/2013 - ] .

OK → See step   11 

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 service information because this may cause a malfunction.

2. Disconnect the A22 ECM connector.
3. Disconnect the A14 inverter with converter assembly connector.
4. Connect the cable to the negative (-) auxiliary battery terminal.
5. Turn the power switch on (IG).
6. Measure the voltage according to the value(s) in the table below.

   *a	Front view of wire harness connector (to ECM)

   NOTE:

   Turning the power switch on (IG) with the ECM connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

7. Turn the power switch off.
8. Disconnect the cable from the negative (-) auxiliary battery terminal.
9. Reconnect the A14 inverter with converter assembly connector.
10. Reconnect the A22 ECM connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   10 

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 service information because this may cause a malfunction.

2. Disconnect the A22 ECM connector.
3. Disconnect the A31 power management control ECU connector.
4. Disconnect the A14 inverter with converter assembly connector.
5. Connect the cable to the negative (-) auxiliary battery terminal.
6. Turn the power switch on (IG).
7. Measure the voltage according to the value(s) in the table below.
