INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - A/C INVERTER)




(a) Disconnect the H15 and H16 HV control ECU connectors.




(b) Disconnect the I11 A/C inverter connector.
(c) Turn the power switch ON (IG).
(d) Measure the voltage between the terminals of the HV control ECU connector and body ground.
Standard voltage:





(e) Turn the power switch OFF.
(f) Measure the resistance between the wire harness side connectors.
Standard resistance (Check for open):





Standard resistance (Check for short)





(g) Reconnect the A/C inverter connector.
(h) Reconnect the HV control ECU connectors.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE INVERTER WITH CONVERTER ASSEMBLY
