Diagnosis Procedure

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.

   Inverter unit		AC 120V outlet		Continuity
   Connector	Terminal	Connector	Terminal
   B82	5	M256	1	Yes
   	1		4

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

   Inverter unit		Ground	Continuity
   Connector	Terminal
   B82	5	--	No
   	1

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

   Inverter unit			Continuity
   Connector	Terminal
   B82	5	1	No

Is the inspection result normal?

YES

GO TO 2.

NO

Repair or replace the harness or connectors.

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.
