How To Turn Off Nissan Armada Backup Camera Beeper

THE REAR SONAR Organisation IS But ONE FORM OF Commuter Assist OFFERED IN SOME NISSAN AND INFINITI VEHICLES. Information technology IS AN EXCELLENT ADDITION TO VEHICLES, PROVIDING ANOTHER LEVEL OF DRIVING CONVENIENCE TO ITS OPERATOR. Later READING THIS Article, YOU WILL HAVE AN UNDERSTANDING OF HOW THE SYSTEM WORKS AND KNOW BASIC TROUBLESHOOTING TIPS THAT Volition Assistance MAKE DIAGNOSIS AND REPAIR OF THE SYSTEM EASIER.

System Basics

The rear sonar sensors transmit a sensor indicate to the sonar control unit (SCU) when detecting an obstacle at the rear of the vehicle. The SCU changes the output of the sonar display and the warning buzzer output frequency changes 4 levels (for center) and iii levels (for corner) according to the detection altitude condition. When the system is working correctly, it will beep slowly when the vehicle approaches an obstacle. As the vehicle gets closer to the obstacle, the beep will become faster. When the rear end of the vehicle is less than x in from the object, the beep becomes continuous. If the organisation detects a motionless object farther than 10 in from the side of the vehicle, the beep will sound for 3 seconds. The system aims to detect objects up to 6 ft from the bumper (detection range approximately 1.8 k (5.9 ft) maximum). The outer corners of the bumper take reduced coverage, and the system only detects objects that are stationary or moving slower than three MPH.

The system diagrams for Infiniti (left) and Nissan (right) vehicles look dissimilar in the ESM, just both vehicle types have 4 rear sensors. In Infiniti models, drivers can cancel the sonar organisation's warning by using the Rear Sonar System (RSS) OFF switch on the instrument panel. Likewise, the sonar sensor's warning is played through the speaker system via the BOSE^® amplifier. In Nissan vehicles, the point is heard through the sonar cablegram. In each vehicle, the sonar command unit (SCU) is below the steering bicycle and easily seen when the lower instrument panel is removed.

The main components of the organisation are the four rear sensors, the SCU and the sonar buzzer. The sonar arrangement starts when the vehicle is put in reverse. The outer sensors detect three levels of distance, and the center sensors detect four levels of distance. In Nissan vehicles, the sonar sensors transmit a sensor indicate to the SCU, which converts information technology into a detection distance signal that is sent to the combination meter via Can communication. In Infiniti vehicles, the sonar sensors transmit a indicate to the audiovisual (AV) control unit via AV communication. In vehicles equipped with brandish units that human activity every bit rear view monitors when the vehicle is in reverse, the communication signals are transmitted from the sensors to the SCU, to the AV control unit, and then to the display unit of measurement and the amplifier for the buzzer to sound.

Notation: If a vehicle owner wants to connect a trailer hitch, apply the CONSULT Work Support particular TRAILER HITCH Manner to plow OFF the center sensor warning buzzer.

Performing Diagnosis

If you receive a repair order to fix a rear sonar sensor concern, obtain whatever information you can about the symptoms from the customer to help check it out. Connect CONSULT and perform "Self Diagnostic Result" for "SONAR." If a Diagnostic Trouble Code (DTC) is displayed, refer to the DTC index and perform the necessary tests since you know where the trouble lies. Chances are a DTC volition appear, only if no DTC code is displayed:

Bank check to run into if mud or other foreign objects are adhering to the sonar sensor.
Cheque for deformation, scratches, or other damage to the sonar sensor.
Check for water accumulated in the sonar sensor.

The system has a self-diagnosis feature that is accessed by the sonar push.

Self-diagnosis Function

The sonar control unit is capable of self-diagnosis. Information technology can notice sensor malfunction or sensor harness open circuits. There are four modes of cocky-diagnosis: inbound diagnostics, requesting number of fault codes, requesting fault codes and idling or clearing fault codes. Be sure to follow these steps in order.

Diagnostic Mode

one. Turn the ignition switch ON. The Rear Sonar Organization OFF switch indicator lamp volition illuminate for 3 seconds and and so turn OFF.

2. Immediately push the Rear Sonar Arrangement OFF switch ten times within v seconds.

3. The sonar buzzer will sound in one case, and the Rear Sonar System OFF switch indicator will wink once.

Although the sensors reply to slightly unlike measurements before they audio the buzzer, the work period for their inspection and repair is the aforementioned. The alarm buzzer has four levels of alerts for the rear center sensors and three levels for the rear corner sensors. The sensor that is closest to the detected object determines the buzz alarm when more than one sensor detects an object. Determine which sensor needs to be repaired according to the DTC displayed on CONSULT. The SCU controls the cablegram's cycle range, which is adjustable with CONSULT.

Use the following tests for the inspection to determine necessary repairs:

The first test is to check the rear sonar sensor circuit continuity.

Turn the ignition OFF
Disconnect the SCU and the sensor you lot are testing.
Bank check continuity and connectors between the SCU and the sensor in question. The locations of each are establish in the Service Manual's wiring diagrams.
Check continuity between the SCU connector and the ground.
If inspection results are not normal, repair or supersede the harness or the connectors for the sensor in question, as necessary.

The next examination is to cheque the rear sonar signal excursion to the battery.

Plough the ignition ON.
Check the voltage betwixt the SCU connector and the basis. If the results are normal, replace the sensor being tested. If the result is not normal, repair or supplant the harness or connectors.

To test the sonar cablegram, repeat the same test procedures that were used for the sensors with the addition of a tertiary examination. Check the sonar buzzer signal excursion to the cablegram power.

Turn the ignition OFF and check the continuity between the sonar control unit of measurement connector terminals.
If the results are normal, the buzzer may need to replaced, and if not, the harness or connectors are probable in demand of replacement.

If CONSULT indicates that the malfunction is due to the SCU, follow this procedure:

Check for blown fuses.
With the ignition ON if there are no blown fuses, examine the power supply circuit past checking the voltage between the SCU harness, connector, and ground. If the consequence is aberrant, the trouble lies in the SCU power supply harness.
If the issue is normal, plow the ignition back to OFF and disconnect the SCU connector.
Check the footing circuit by examining continuity between the SCU harness connector and ground. If you notice a trouble with the harness, repair or replace it, as necessary.
