Diagnosis Procedure
- CHECK HARNESS BETWEEN INVERTER UNIT AND AC 120 V OUTLET
- Turn ignition switch OFF.
- Disconnect inverter unit connector and AC 120 V outlet connector.
- 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 - Check for continuity between inverter unit harness connector and ground.
Inverter unit Ground Continuity Connector Terminal M143 5 Not existed 1 - 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 STEP 2.
NO
Repair or replace the harnesses or connectors.
- CHECK INVERTER UNIT OUTPUT SIGNAL
- Connect inverter unit connector and AC 120 V outlet connector.
- Turn ignition switch ON.
- AC 120 V outlet main switch ON. (AC 120 V outlet main switch indicator ON)
- 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 STEP 3
NO
Replace inverter unit.
- CHECK AC 120 V OUTLET VOLTAGE
- AC 120 V outlet main switch ON. (AC 120 V outlet main switch indicator ON)
- Check voltage between AC 120 V outlet.
