Diagnosis Procedure

1. Turn ignition switch OFF.
2. Disconnect inverter unit connector and AC 120 V outlet main switch connector.
3. Check continuity between inverter unit harness connector and AC 120 V main switch harness connector.

   Inverter unit		AC 120 V outlet main switch		Continuity
   Connector	Terminal	Connector	Terminal
   M143	7	M144	5	Existed

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

   Inverter unit		Ground	Continuity
   Connector	Terminal
   M143	7		Not existed
