Diagnosis Procedure

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.

   Inverter unit		AC 120 V outlet		Continuity
   Connector	Terminal	Connector	Terminal
   M143	5	M145	1	Existed
   	1		2

4. Check for continuity between inverter unit harness connector and ground.

   Inverter unit		Ground	Continuity
   Connector	Terminal
   M143	5		Not existed
   	1

5. Check for continuity between inverter unit harness connector.

   Inverter unit			Continuity
   Connector	Terminal
   M143	5	1	Not existed

   Is the inspection result normal? 

   YES: GO TO 2.

   NO: Repair or replace the harnesses or connectors.

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.

   Terminals				Condition	Voltage (Approx.)
   (+)		(-)
   Inverter unit		Inverter unit		AC 120 V outlet main switch
   Connector	Terminal	Connector	Terminal
   M143	5	M143	1	OFF	0 V
   				ON	AC 120 V

   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.

1. AC 120 V outlet main switch ON. (AC 120 V outlet main switch indicator ON)
2. Check voltage between AC 120 V outlet.

   Terminals		Condition	Voltage (Approx.)
   (+)	(-)
   AC 120 V outlet		AC 120 V outlet main switch
   Terminal
   1	2	OFF	0 V
   		ON	AC 120 V

Is the inspection result normal? 

YES: INSPECTION END

NO: Replace AC 120 V outlet.
