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 information because this may cause a malfunction.

2. Disconnect connector D28 from the ECM.
3. Disconnect connector A59 from the inverter with converter assembly.
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.

   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. Connect the inverter with converter assembly connector.
10. Connect the 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 repair information because this may cause a malfunction.

2. Disconnect connector D28 from the ECM.
3. Disconnect connector A21 from the power management control ECU.
4. Disconnect connector A59 from the inverter with converter assembly.
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.
