What are the reasons for the non-display of the reversing image in the Mercedes-Benz E300L?

Reasons for the non-display of the reversing image in the Mercedes-Benz E300L: 1. Wiring issues: It is highly likely due to poor wiring connections. It is necessary to promptly inspect the wiring and the connection points installed in the vehicle to check for any loose connections. If found, simply secure the loose connections properly. 2. Video power cable issues: It could also be due to aging of the video power cable. Try replacing it with a new one. 3. Chip issues: Prolonged use of the reversing camera may lead to poor light sensitivity of the chip, resulting in a snowy image or, in severe cases, the black screen issue mentioned today. 4. Hardware issues: Damaged hardware can only be handled by a mechanic.

Recently, my friend's Mercedes-Benz E300L also encountered the issue of a black screen with the reversing camera. After struggling for a while, we finally figured out the cause. If the screen suddenly goes dark when reversing, there's an 80% chance the rear camera is the culprit. In my case, I found the camera completely covered in mud, and it worked fine after cleaning. If the camera isn't dirty, check the wiring harness on the left side of the trunk—frequent opening and closing can cause poor contact in the wiring. It's also common for the Mercedes infotainment system to act up occasionally; try rebooting the system by holding the phone button on the steering wheel and the mute button on the center console for ten seconds. Additionally, the fuse box is located in the passenger footwell, and a blown fuse labeled for the camera can also cause the issue. If you can't figure it out, head straight to the dealership—reversing without a camera is too dangerous, especially in rainy weather when rearview mirrors are hard to see, making it easy to scrape against walls.

My experience shows that troubleshooting a black screen on a Mercedes reversing camera requires multi-angle inspection. First, check the camera itself - water ingress after heavy rain or physical damage from impacts are the most common issues. Next, examine the wiring harness connectors in the trunk, as frequent door operations can cause cable fatigue fractures. Then rule out infotainment system problems: failed system updates or software crashes may affect display functionality. I've also encountered cases where the reversing camera was accidentally disabled in the settings menu, so it's worth checking the configuration items. If all the above checks out, inspect the F11 fuse (10A protection component) in the fuse box under the driver's seat - a blown fuse will cut the circuit. For DIY repairs, prepare a multimeter to test circuit voltage. If unsure, visit an authorized dealer to read fault codes with Mercedes diagnostic equipment.

After more than a decade of repairing cars, I've encountered numerous Mercedes-Benz reversing camera failures, with three most common issues. The first is the rear camera being completely damaged, usually from high-pressure car wash jets or shattered lenses. The second issue lies in the wiring harness hidden in the left corner of the trunk; bending it repeatedly about a hundred times can break the wires, especially prone in Mercedes-Benz E-Class models. The third is a control module failure, located behind the trunk liner, where rainwater seeping into the connectors can burn out the circuit board. The easiest fix is to first clean the camera lens of dust, then restart the infotainment system using the reset button. The fuse is located at position F11 under the passenger seat—try replacing it with a new one. If the screen remains dark, it usually means you'll have to dismantle the interior to check the wiring.

A malfunctioning reversing camera is the most troublesome blind spot. Last time during a heavy rain, I encountered this issue while driving my E300L. For safety, first park the car steadily and turn on the hazard lights, then shift into reverse to check if the radar is functioning normally. If the camera image disappears alone, first inspect the camera: clean any mud or dirt with a wet cloth, and replace it if physically damaged. Then, perform a soft reboot in the car's infotainment system by holding down the volume and phone buttons simultaneously for ten seconds to reset. A special reminder: don't attempt to remove the trunk liner yourself—Mercedes wiring is as complex as a spider's web. In case of a short circuit or module failure, it's best to let the 4S professionals handle it—they have anti-static tools and circuit diagrams, and can pinpoint within half an hour whether it's a blown fuse or a damaged control box. Remember to clean the camera during regular maintenance to prevent issues.
