PARK ASSIST / MONITORING: INTUITIVE PARKING ASSIST SYSTEM: Back Sonar Sensor LH Circuit
- Back Sonar Sensor LH Circuit

DESCRIPTION

The ultrasonic sensor sends and receives ultrasonic waves. Based on the received wave, the sensor calculates the approximate distance between the vehicle and the obstacle, and sends the distance value as a signal to the clearance warning ECU.

(a) Disconnect the P3 No. 1 ultrasonic sensor (rear center sensor LH) connector.





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

Standard Resistance:





NG -- REPLACE NO. 1 ULTRASONIC SENSOR (REAR CENTER SENSOR LH) Removal
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (REAR CENTER SENSOR LH - CLEARANCE WARNING ECU)

(a) Disconnect the P3 No. 1 ultrasonic sensor (rear center sensor LH) connector.

(b) Disconnect the F25 clearance warning ECU connector.

(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 SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE Intuitive Parking Assist System
