Diagnosis Procedure

INFOID:0000000009174852

Regarding Wiring Diagram information, refer to 

PWO-16, "Wiring Diagram"

.

1.

CHECK HARNESS BETWEEN INVERTER UNIT AND AC 120V OUTLET

1. Turn ignition switch OFF.

2. Disconnect inverter unit and AC 120V outlet connectors.

3. Check continuity between inverter unit connector B82 terminals 5, 1 and AC 120V outlet connector M256

terminals 1, 4.

4. Check continuity between inverter unit connector B82 terminals 5, 1 and ground.

5. Check continuity between inverter unit connector B82 terminals 5 and 1.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace the harness or connectors.

2.

CHECK INVERTER UNIT OUTPUT SIGNAL

1. Connect inverter unit and AC 120V outlet connectors. 

2. Turn ignition switch ON.

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

4. Check voltage between inverter unit connector B82 terminals 5 and 1.

CAUTION:

• To measure AC 120V 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 120V OUTLET VOLTAGE

Check voltage between AC 120V outlet M256 terminals 1 and 4.
