The ‘Rear View Camera Inoperative’ warning in Mercedes-Benz vehicles indicates a malfunction in the reversing camera system. This system enhances safety by providing visual assistance when reversing or parking. When the system fails, the display may go blank, distorted, or show the message ‘Rear View Camera Inoperative’ on the cluster or infotainment screen. This article explains the function of the rear view camera, common causes of malfunction, diagnostic steps, and repair solutions.
What is the Rear View Camera System?
The rear view camera system consists of a camera module mounted at the rear of the vehicle, wiring harnesses, a control unit, and the infotainment display. In advanced models, the system integrates with parking sensors, 360-degree camera systems, and driver assistance features.

Causes of Rear View Camera Inoperative
The most common causes include:

2. Wiring harness damage or loose connectors at the trunk or camera module.
3. Faulty camera control unit or ECU.
4. Software errors in the infotainment or camera system.
5. Blown fuse related to the camera circuit.
6. Dirty, fogged, or obstructed camera lens.
7. Voltage or power supply issues affecting the camera.
How to Diagnose Rear View Camera Issues
Begin by inspecting the camera lens for dirt, condensation, or damage. Check wiring and connectors in the trunk area, which are prone to bending and damage. Verify the fuse for the camera circuit. Using Mercedes-Benz diagnostic tools such as Xentry, DTS Monaco, or the MBCOD Box with ELM327, scan for fault codes such as B2234 (camera module fault), B15F0 (video signal error), or U0235 (lost communication with camera ECU). Live data can confirm camera activation status and video signal transmission.

2. Replace faulty or water-damaged rear view camera modules.
3. Repair or replace damaged wiring harnesses or connectors.
4. Replace or reprogram the camera control unit if defective.
5. Update infotainment or ECU software if required.
6. Replace blown fuses and ensure proper power supply to the camera.
7. Clear stored fault codes and verify the camera displays correctly.
Preventive Maintenance for Camera System
To avoid camera malfunctions, regularly clean the lens, avoid high-pressure washing directly on the camera, and ensure trunk wiring is not pinched or damaged. Keep software updated and respond promptly to early warnings.
