Why is the reversing camera not displaying?

[OMolly]

The reasons why the reversing camera screen does not display are as follows: 1. Poor contact in the reversing camera's wiring and switch: If the connecting wire between the camera and the vehicle's display screen falls off, or the reversing camera switch is damaged, there will be an issue with the reversing camera not displaying. In this case, the wiring needs to be reconnected, and if necessary, a new switch can be replaced. 2. Reversing camera module malfunction: There are many reasons for the reversing camera module to malfunction, including system disorder, module producing garbled code, and reversing camera formatting. In this situation, it is necessary to go to a repair shop and have a professional inspect it.

Last time I encountered this issue, I first shifted the car into reverse and then went to the rear to check the camera—sure enough, it was covered in mud splatters. After going home and wiping it with a wet cloth, the image became clear immediately. If the display still doesn't work after cleaning, you should check if the camera has any cracks or water ingress. Loose wiring connections are also common, especially in cars with frequently opened trunks. The worst-case scenario is a blown fuse, so you’ll need to consult the manual to locate the corresponding fuse box. If you still can’t figure it out, just drive to a repair shop. The mechanics can quickly diagnose the problem with a multimeter, which is much more efficient than guessing blindly. Remember to specifically rinse the camera area the next time you wash your car—it’s especially prone to dust buildup during the rainy season.

Cars with aftermarket infotainment screens are most prone to this issue. My buddy's newly installed reverse camera went black the next day - turned out the protocol cable wasn't securely connected at the modification shop. Aftermarket device connectors tend to oxidize, especially wiring routed through the spare tire well where prolonged vibration can desolder joints. For factory systems, focus on checking the R-gear trigger wire - sometimes the parking sensors work but the camera doesn't display due to poor contact. Wiring harnesses near trunk hinges frequently fracture from repeated bending; peeling back the rubber sleeve reveals wear marks. If you're unsure, don't force it - most auto shops charge reasonably for reverse camera diagnostics these days.

Three key areas to watch out for in older cars: The camera lens may age and turn white, making it completely unclear in rainy weather; wiring harnesses may have their insulation chewed through by rodents; and capacitors on the car's motherboard may bulge. Last year, I learned this the hard way after taking over a ten-year-old car—replacing the camera only cost eighty bucks. Nowadays, cameras online range from tens to hundreds, and replacing them yourself isn't difficult; just pry open the license plate light cover. Remember to buy one with night vision for safer reversing at night. When modifying wiring, always ensure waterproofing—last time I saw someone use regular tape to wrap the connection, and it short-circuited in the rain, burning out the fuse.
