INSPECTION PROCEDURE

PROCEDURE

1. INSPECT NO. 1 ULTRASONIC SENSOR

(a) Remove the No. 1 ultrasonic sensor.





(b) Measure the resistance according to the value(s) in the table below.

Standard resistance:





NG -- REPLACE NO. 1 ULTRASONIC SENSOR
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (CLEARANCE WARNING ECU - NO. 1 ULTRASONIC SENSOR)

(a) Disconnect the C9 connector from the clearance warning ECU.





(b) Disconnect the U2 connector from the No. 1 ultrasonic sensor.





(c) Measure the resistance according to the value(s) in the table below.

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
