How to Solve the Flickering Issue of Reversing Camera?

Here are the solutions for the flickering issue of reversing camera: 1. Poor line contact may cause the reversing camera to flicker. The wiring may have aged. Check if there is any loose connection at the camera connection point. You can try replacing it with a new power cable to solve the problem. 2. When starting the car, the voltage may drop momentarily. Generally, reversing camera products have high voltage requirements, normally around 12 volts. When other car devices are also consuming power, the voltage may drop below the required level, leading to insufficient power supply and causing screen flickering. 3. Screen flickering may also be caused by the camera's wiring. When starting the car, the instantaneous voltage may be unstable, resulting in insufficient power. The amplitude of the camera's wiring may fluctuate significantly, causing abnormal signal output. Additionally, prolonged use of the camera may lead to screen jitter and other issues. For the latter two situations, it is recommended to visit a repair shop for inspection.
As a technician who has repaired hundreds of vehicles, I recommend troubleshooting in three steps. The most likely issue is a dirty camera lens or obstruction by mud; try cleaning it with a wet cloth. If that doesn’t work, inspect the trunk wiring harness, where the camera connector is located—repeated opening and closing of the trunk can loosen or wear out the insulation, and I’ve seen many cases of flickering screens due to damaged wiring. Lastly, check the infotainment system; try restoring factory settings, but remember to back up navigation routes first. If the problem suddenly occurs after rain, it’s likely due to a deteriorated camera seal letting in water—this requires replacement. A third-party part at Tiger Maintenance costs around 300-500 yuan.
Last time my reversing camera flickered like disco lights, it was actually caused by modifying the reverse lights. Some owners replace them with brighter LED reverse lights, resulting in current interference with the camera signal. When you engage reverse gear, have someone observe the screen while you toggle the reverse lights on and off. Also, check the license plate light position - the camera's power cable often runs through the same rubber sleeve, which can melt in summer heat causing short circuits. For DIY troubleshooting, focus on these two areas: open the trunk liner to check if wiring got crushed; lift the trunk mat to see if cable tie mounts came loose causing tension.
