![]() When collision repairs are necessary, Nissan North America strongly recommends that any repairs use Genuine Nissan replacement parts designed for the specific Nissan vehicle being repaired. This forces the body shop to cut the opening, introducing potential measurement or placement error, not to mention requiring time-consuming extra labor. Some non-OE liftgates may come without pre-drilled holes for camera installation. ![]() You cannot use a hammer and dolly to work the camera housing into the proper alignment. It is important to note that the inner and outer panels of the liftgate in the 2011-14 Murano are made of polypropylene. Non-symmetric shape, variations in size due to less stringent aftermarket production tolerances, and fitment issues with hinges and other mounting hardware are just a few of the causes of difficulty in achieving a proper alignment of the liftgate.įor all of these reasons, repair or replacement of liftgate or decklid components should only be performed with Genuine Nissan replacement parts. Aftermarket or recycled liftgates may have differences in build specifications that result in issues with camera alignment and performance. Repairs to a liftgate or decklid that contains a rearview camera require precision alignment of the repaired or replaced component. Any collision that affects the alignment of the liftgate or decklid will likely alter the direction or angle in which the camera is pointed, destroying the accuracy of rear view imaging information provided to the driver.Īdditionally, any wiring fault or damage to control modules for the audio visual system, of which the backup camera technology is a part, can cause performance problems with the RearView Monitor. The camera is always housed in the rear liftgate (tailgate) or decklid, depending on the vehicle model. The company introduced its RearView Monitor system at the 2000 New York International Auto Show, with North American market launch in March 2001 as optional equipment on the 2002 Q45 sedan.įor collision repairs, detailed specifications and measurement information for liftgates, decklids, and other components are available in the Nissan service manual section “BRM” (Body Repair Manual). Nissan’s Infiniti luxury division was the first to incorporate backup camera technology in a production vehicle for the North American market. Unlike your significant other or co-worker in the passenger seat, checking the rear view mirror and not-so-secretly applying the brakes, Nissan’s RearView Monitor helps you back up without passing judgment on your maneuvering skills. Perhaps that is one reason for the system’s immense popularity. ![]() It doesn’t actually scream at you, of course. A red line screams “Hey! You’re only 1.5 feet away!” Using the familiar green, yellow and red colors of a traffic light, the lines start at ten feet away and give an increasing sense of urgency as the vehicle’s predicted travel path puts it closer to nearby objects. When the transmission is in reverse, lines of different colors on the monitor indicate the distance from objects behind the vehicle. The AV Control Unit is connected via CAN communication to the ECM and the rear camera and in-dash display unit. The predictive course lines project where the vehicle is headed based on input to the AV Control Unit from the steering angle sensor. The fixed guide lines give the driver a backwards-facing view, showing in real time exactly where the vehicle is relative to objects immediately behind it. It sends this combined visual to the in-dash display unit. ![]() The AV Control Unit then generates fixed guide lines and predictive course lines in red, green or yellow, and overlays them onto the rear view images. The rear view camera sends its images to the AV Control Unit. ![]() When the transmission is shifted into reverse, the rear view camera in the 2011-14 Murano Z51 receives power from, and is operated according to, commands generated by the AV (audio visual) Control Unit. Green lines mark distances of ten (4) and seven feet (3), a yellow line (2) warns that the vehicle is within three feet, and a red line (1) indicates there is only a 1.5 foot space remaining between the vehicle and an object behind it. Guiding lines indicate the vehicle width (5) and distances to objects with reference to the vehicle body line (A). When the gear selector lever on the 2011-’14 Murano Z51 is in Reverse, the Nissan RearView Monitor system displays predicted course lines (6) showing the direction the vehicle will travel, based on how the steering wheel is positioned. ![]()
