INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - NO. 1 CIRCUIT BREAKER SENSOR)




(a) Disconnect the H16 HV control ECU connector.

(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 No. 1 circuit breaker sensor connector.
(h) Reconnect the HV control ECU connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE NO. 1 CIRCUIT BREAKER SENSOR
