Back Sonar Sensor RH Circuit

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

INSPECTION PROCEDURE

PROCEDURE

1. INSPECT NO. 1 ULTRASONIC SENSOR (REAR CENTER SENSOR RH)

(a) Disconnect the P2 No. 1 ultrasonic sensor (rear center sensor RH) 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 RH) Removal
OK -- Continue to next step.

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

(a) Disconnect the P2 No. 1 ultrasonic sensor (rear center sensor RH) 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
