No: -
- CHECK THE CONNECTING CONDITION OF CONNECTOR (Inverter with converter assembly LOW PRESSURE CONNECTOR)
.CAUTION: Make sure to wear insulated gloves and protective goggles during the work.
- Check that the Service plug is disconnected. Ref. to HYBRID ELECTRIC VEHICLE>SERVICE PLUG .
- Check the connecting condition of low pressure connectors (HV23) and (HV24) in Inverter with converter assembly and check the relevant terminals for contact pressure, deformation and intrusion of water or foreign matter. Ref. to HYBRID ELECTRIC VEHICLE>INVERTER AND CONVERTER ASSEMBLY
.NOTE: When connecting the connector, insert to the end with the lock lever raised, then fold the lock lever completely until a click is heard. After connected, make sure that the lock claw does not loosen and pull the connector to see that it does not come off.
Is there looseness at the connector connection, or any poor contact, deformation or intrusion of water or foreign matter at the relevant terminals?
Yes: Connect the connector securely. Or repair the poor contact of connector.
No: Go to 3.
- CHECK HV BATTERY HIGH-VOLTAGE LINE CIRCUIT
.
Check HV BATTERY HIGH-VOLTAGE LINE CIRCUIT. Ref. to P-HEV HYBRID POWERTRAIN CONTROL (DIAGNOSTICS)>DIAGNOSTICS WITH PHENOMENON>INSPECTION>HV BATTERY HIGH-VOLTAGE LINE CIRCUIT .
Is the HV BATTERY HIGH-VOLTAGE LINE CIRCUIT OK?
Yes: Go to 4.
No: Repair according to HV BATTERY HIGH-VOLTAGE LINE CIRCUIT inspection. And then, Go to 4.
- CHECK Inverter low-voltage circuit
.
Check Inverter low-voltage circuit. Ref. to P-HEV HYBRID POWERTRAIN CONTROL (DIAGNOSTICS)>DIAGNOSTICS WITH PHENOMENON>INSPECTION>INVERTER LOW-VOLTAGE CIRCUIT .
Is the Inverter low-voltage circuit OK?
Yes: Replace Inverter with converter assembly. Ref. to HYBRID ELECTRIC VEHICLE>INVERTER AND CONVERTER ASSEMBLY .
No: Repair according to Inverter low-voltage circuit inspection. Then, replace the Inverter with converter assembly. Ref. to HYBRID ELECTRIC VEHICLE>INVERTER AND CONVERTER ASSEMBLY .
