Diagnosis Procedure

INFOID:0000000006257091

1.

CHECK HARNESS BETWEEN INVERTER UNIT AND AC 120 V OUTLET

1.

Turn ignition switch OFF.

2.

Disconnect inverter unit connector and AC 120 V outlet connector.

3.

Check for continuity between the inverter unit harness connector and AC 120 V outlet harness connector.

4.

Check for continuity between inverter unit harness connector and ground.

5.

Check for continuity between inverter unit harness connector.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace the harnesses or connectors.

2.

CHECK INVERTER UNIT OUTPUT SIGNAL

1.

Connect inverter unit connector and AC 120 V outlet connector. 

2.

Turn ignition switch ON.

3.

AC 120 V outlet main switch ON. (AC 120 V outlet main switch indicator ON)

4.

Check voltage between inverter unit harness connector.

CAUTION:

• To measure AC 120 V output signal, always use the circuit tester AC range.
• Never allow the probes to contact each other.
Is the inspection result normal?

YES

>> GO TO 3

NO

>> Replace inverter unit. 

3.

CHECK AC 120 V OUTLET VOLTAGE

1.

AC 120 V outlet main switch ON. (AC 120 V outlet main switch indicator ON)

2.

Check voltage between AC 120 V outlet.
