Diagnosis Procedure

Regarding Wiring Diagram information, refer to WIRING DIAGRAM .

1. CHECK HARNESS BETWEEN INVERTER UNIT AND AC 120 V OUTLET MAIN SWITCH
   
   
   1. Turn ignition switch OFF.
   2. Disconnect inverter unit and AC 120 V outlet main switch connectors.
   3. Check continuity between inverter unit connector B82 terminal 7 and AC 120 V main switch connector M88 terminal 5.

      Inverter unit		AC 120 V outlet main switch		Continuity
      Connector	Terminal	Connector	Terminal
      B82	7	M88	5	Yes

   4. Check continuity between inverter unit connector B82 terminal 7 and ground.

      Inverter unit		Ground	Continuity
      Connector	Terminal
      B82	7		No

   Is the inspection result normal?

   YES 

   GO TO STEP 2. 

   NO 

   Repair or replace the harness or connectors.

2. CHECK AC 120 V OUTLET MAIN SWITCH GROUND CIRCUIT
   
   

   Check continuity between AC 120 V outlet main switch connector M88 terminal 6 and ground.

   AC 120 V outlet main switch		Ground	Continuity
   Connector	Terminal
   M88	6		Yes

   Is the inspection result normal?

   YES 

   GO TO STEP 3. 

   NO 

   Repair AC 120 V outlet main switch ground circuit.

3. CHECK AC 120 V OUTLET MAIN SWITCH INDICATOR OUTPUT SIGNAL
   
   
   1. Connect AC 120 V outlet main switch and inverter unit connectors.
   2. Turn ignition switch ON.
   3. AC 120 V outlet main switch ON.
   4. Check voltage between the inverter unit connector B82 terminal 7 and ground.

      Inverter unit		Ground	Condition	Voltage (Approx.)
      Connector	Terminal		AC 120V outlet main switch
      B82	7	-	OFF	0V
      			ON	5.2V

   Is the inspection result normal?

   YES 

   Replace AC 120 V outlet main switch.

   NO 

   Replace inverter unit.
