What are the reasons for the Nissan Teana's reversing camera not displaying?

The reasons for the Nissan Teana's reversing camera not displaying are: 1. The power cable is loose, causing the camera to malfunction; 2. The display screen is faulty. Taking the 2021 Teana as an example, its body dimensions are: length 4901mm, width 1850mm, height 1450mm, wheelbase 2825mm, fuel tank capacity 61.3l, and curb weight 1456kg. The 2021 Teana features a MacPherson strut independent front suspension and a trapezoidal control arm multi-link independent rear suspension. It is equipped with a 2.0l naturally aspirated engine, delivering a maximum horsepower of 156ps, maximum power of 115kw, maximum torque of 197nm, and is paired with a CVT continuously variable transmission.

As someone who frequently tinkers with their beloved car, I find it quite common for the Nissan Teana's reversing camera to stop displaying. Possible causes include a malfunctioning camera itself, especially when the lens is obscured by mud or rainwater; or a loose or broken wire connecting the rear camera to the trunk, as repeated opening of the tailgate can damage the interface. Sometimes, the car's display software crashes, possibly due to a failed system update or too many bugs, requiring a vehicle restart or a reset of the infotainment system. Additionally, a blown fuse is another common issue—it melts to protect the circuit when the current is too high, and checking the fuse box can locate the relevant position. I recommend first cleaning the camera with a damp cloth and then inspecting the wire connections; if that doesn’t work, try holding down the power button to restart. It’s best not to delay, as this issue can easily lead to reversing errors, so timely inspection at a professional repair shop is more reliable.

I've encountered situations where the Altima's reversing camera suddenly stops working, which is quite annoying—relying solely on mirrors when reversing is really inconvenient. The camera might have been damaged by impact or covered in dust, causing blurry images, so try cleaning the lens first. The wiring at the trunk connection could be loose or aged and broken; check if those small plugs are securely connected. Also, the car's system occasionally malfunctions, freezing and becoming unresponsive, requiring an engine restart to refresh the software. Power issues, like a blown fuse, are another possible cause—just locate it using the manual and replace it. I think the simple steps are to clean first, then restart; if that doesn't fix it, just drive to the 4S shop. They can usually quickly diagnose the issue and replace the faulty parts to resolve it.

When I was reversing, I noticed the camera image was gone, and I'm concerned about safety. As a regular driver, I know it's important to address this promptly. Possible reasons include: the camera might be damaged due to vibration or high temperatures causing internal failure; unstable wiring connections in the trunk, possibly from rough roads loosening the plugs; the system software might be frozen and needs a screen restart; or a blown fuse cutting off power. I suggest not experimenting on your own and instead taking it directly to a mechanic to check the camera and wiring, especially since the Altima's rearview camera near the trunk is quite prone to damage. Having these components inspected during regular maintenance can prevent issues and keep safety a top priority while driving.
