What Causes the Black Screen of Mercedes-Benz Reversing Camera?
4 Answers
The reasons for the black screen of the Mercedes-Benz reversing camera include camera damage, onboard computer malfunction, poor gear engagement, dead battery, etc. When the reversing camera does not display, it is necessary to immediately go to a repair shop or 4S store for professional repair to avoid affecting the normal use of the car. Taking the Mercedes-Benz E-Class 2021 E260L Sport as an example, the following related introductions are provided: 1. Dimensions: The manufacturer of this car is Beijing Benz, and its class is mid-size luxury car. The car has a length, width, and height of 5078mm, 1860mm, and 1484mm respectively, with a wheelbase of 3079mm. 2. Powertrain: The drivetrain is front-engine, rear-wheel drive, with a 9-speed automatic transmission. The front suspension type is multi-link independent suspension, and the rear suspension type is also multi-link independent suspension. The steering assistance type is electric power steering, and the body structure is unibody.
I've been driving a Mercedes-Benz E-Class for several years, and it's really frustrating when the reversing camera suddenly goes black. The most common issue is the camera lens being covered by mud or water stains, so check the lens cleanliness when parking. Wiring problems are also quite common, especially after repeatedly opening and closing the trunk, as the cable connecting the camera can easily loosen or get damaged—try manually tightening the connector. A blown fuse is another frequent cause; just locate and replace the corresponding fuse in the fuse box for the reversing camera. Occasionally, the software acts up, and restarting the infotainment system or checking for system updates can resolve it. If the camera itself is broken or there's a module malfunction, such as water damage or aging, you'll have to send it for repair. Daily habits like protecting the camera area from impacts, avoiding dragging on the ground, and regularly cleaning the lens during car washes can significantly reduce issues. Be extra cautious when reversing at night—temporarily rely on manual radar or mirrors to assist, ensuring safety comes first.
As someone who frequently helps friends with car repairs, troubleshooting a black screen on a Mercedes reversing camera requires a systematic approach. First, check if the camera lens is obstructed or scratched, and clean it with a soft cloth. Next, inspect the wiring harness, looking for connectors at the rear of the vehicle or near the trunk lid to see if they are oxidized or loose. A blown fuse is a common issue, and replacing one from the fuse box is inexpensive. Using a diagnostic tool to read fault codes can provide clearer indications, such as sensor failure or module malfunction. Software bugs can be tested by resetting the infotainment system. Unstable system voltage or insufficient battery power can also trigger false alerts. For prevention, it's recommended to regularly check the wiring harness sealant to avoid water seepage and component corrosion. After professional servicing, the reversing image should restore clarity, significantly improving visibility and safety.
Don't panic when encountering a reversing camera black screen. Immediately stop the car and check if the camera lens is obstructed by dirt. If a simple wipe doesn't help, try turning off the engine and restarting the vehicle. Loose wiring harnesses are a common cause - gently push and pull the connectors near the trunk area might restore function. In cold weather, systems are prone to malfunction; wait a few minutes for the interior to warm up before retrying. For blown fuses, consult the manual to locate and replace them. If the black screen persists, avoid forcing reverse maneuvers to prevent collisions with pedestrians or obstacles. Mercedes vehicles have auxiliary radar audio alerts, but missing video poses higher risks. Take the car to professional technicians to inspect circuits and modules, ensuring a safe driving environment. During regular maintenance, remind technicians to test the system as preventive care.
