Code B2722 Nissan Description

With power and ground supplied to the sonar sensors, the sonar sensors transmit an ultrasonic signal. This signal is reflected back to the sensor by objects large enough and close enough to be detected. The sonar sensors measure the time from the transmitted signal to the time the signal is reflected back and send this information to the Sonar Control Unit. The Sonar Control Unit sets the Diagnostic Trouble Code (DTC) when the Rear Sonar Sensor Right Inner is out of factory specifications.
