How can I test my rear sonar system?
The first test is to check the rear sonar sensor circuit continuity. Disconnect the SCU and the sensor you are testing. Check continuity and connectors between the SCU and the sensor in question. The locations of each are found in the Service Manual’s wiring diagrams. Check continuity between the SCU connector and the ground.
How is the distance calculated with an ultrasonic sensor?
We also did the experiment with the 5V Ultrasonic sonar sensor HC-SR04, using batteries for extra power. This ultrasonic sonar sensor measures distances from 2cm to 400cm with an accuracy up to 3mm. The measurement angle is approximately 15°. The HC-SR04sonar sensor comprises a ultrasonic transmitter, an ultrasonic receiver and a control circuit.
How is the sonar system capable of self diagnosis?
The sonar control unit is capable of self-diagnosis. It can detect sensor malfunction or sensor harness open circuits. There are four modes of self-diagnosis: entering diagnostics, requesting number of fault codes, requesting fault codes and idling or clearing fault codes.
Where is the Sonar Control Unit on a car?
In each vehicle, the sonar control unit (SCU) is below the steering wheel and easily seen when the lower instrument panel is removed. The main components of the system are the four rear sensors, the SCU and the sonar buzzer. The sonar system starts when the vehicle is put in reverse.

Where is the sonar buzzer located on a Nissan?
In Nissan vehicles, the signal is heard through the sonar buzzer. In each vehicle, the sonar control unit (SCU) is below the steering wheel and easily seen when the lower instrument panel is removed. The main components of the system are the four rear sensors, the SCU and the sonar buzzer.
What is the sonar system on a Nissan ESM?
The system diagrams for Infiniti (left) and Nissan (right) vehicles look different in the ESM, but both vehicle types have four rear sensors. In Infiniti models, drivers can cancel the sonar system’s alert by using the Rear Sonar System (RSS) OFF switch on the instrument panel.
How do I Turn Off the rear sonar system?
Be sure to follow these steps in order. 1. Turn the ignition switch ON. The Rear Sonar System OFF switch indicator lamp will illuminate for 3 seconds and then turn OFF. 2. Immediately push the Rear Sonar System OFF switch ten times within 5 seconds. 3. The sonar buzzer will sound once, and the Rear Sonar System OFF switch indicator will flash once.
