Case Study: Mercedes 360 Camera Not Working, Diagnosis & Fix
When your Mercedes 360° camera system stops working, the loss of that all-around view can turn simple parking maneuvers into stressful guesswork. In newer Mercedes models, this system depends on four high-precision cameras, multiple control units, and calibration data stored within the network.
A single fault in this chain whether from voltage drop, CAN interruption, or lost calibration can make the entire view unavailable.
This case study details how a Mercedes-Benz C-Class with a “360 Camera Not Working” message was diagnosed and repaired using professional Mercedes diagnostic tools.

Customer Complaint
The owner of a Mercedes-Benz C-Class (W205) reported that the 360° camera stopped functioning.
Each time the system was activated, an error appeared on the display:
“360° Camera Unavailable – Consult Workshop.”
No visual feed was displayed from any camera, and the system failed to enter panoramic or split-screen mode.
Diagnostic Workflow
Step 1 : Fault Code Scan
Using XENTRY Diagnostic, the technician performed a full system scan.
The following fault was logged in the 360 Camera Control Unit (A40/6):
B1FBD54 – Control Unit 360 Camera has malfunctioned. Calibration missing.
The fault was stored as current, meaning the system refused to activate until calibration data was restored.
Step 2 : Actual Values Review
Live data confirmed all four camera channels were detected but flagged as Not Calibrated:
| Camera Position | Status | Voltage Supply | Communication |
|---|---|---|---|
| Front | NOT CALIBRATED | 12.1 V | OK |
| Rear | NOT CALIBRATED | 12.2 V | OK |
| Left Mirror | NOT CALIBRATED | 12.0 V | OK |
| Right Mirror | NOT CALIBRATED | 12.0 V | OK |
This ruled out power or wiring loss calibration data was simply missing or corrupted.
Step 3 : Visual & Electrical Inspection
- – Checked all four camera lenses: no cracks, fogging, or dirt.
- – Verified connectors under mirrors, tailgate, and grille: secure & corrosion-free.
- – Checked CAN and LIN lines between cameras and control unit resistance within spec (~60 Ω).
No physical fault was found. The system’s inability to initialize confirmed a software or calibration issue.
Step 4 : Calibration Procedure
Preparation
- 1. Vehicle positioned on perfectly level surface.
- 2. All lenses cleaned with microfiber cloth and camera cleaner.
- 3. Ignition ON, engine OFF to maintain stable voltage.
Calibration Using XENTRY
- 1. Opened the “Camera Calibration” routine under the 360-Camera control unit.
- 2. Followed on-screen instructions to calibrate each camera individually.
- 3. Verified on diagnostic screen that all four cameras returned status: CALIBRATED.
Verification
- – Activated the 360-camera display from the COMAND system.
- – The panoramic view loaded immediately, showing clear and correctly aligned images.
- – Cleared fault memory and re-scanned: No active or stored codes.
Outcome
| Before Repair | After Calibration |
|---|---|
| Error: “360 Camera Unavailable” | No warnings |
| All cameras “Not Calibrated” | All cameras “Calibrated” |
| No image feed | Full 360° panoramic view |
| Fault B1FBD54 active | Fault cleared |
Result: 360-degree camera fully restored after successful calibration.
Safety Restored: Accurate surround-view and parking assistance functionality confirmed.
Technician’s Insight
“When every camera reports Not Calibrated simultaneously, start with software.
Physical damage usually affects only one channel system-wide errors point to lost calibration or voltage drops during updates.”

Lessons & Preventive Tips
- – Keep camera lenses clean to prevent focus or detection errors.
- – Avoid disconnecting the vehicle battery during system updates voltage drops can erase calibration data.
- – Schedule annual 360-camera calibration after bodywork, windshield, or mirror replacement.
- – Always use XENTRY or approved Mercedes software; third-party tools may not support calibration sequences.

FAQs: Mercedes 360 Camera Not Working
Q1. Why is my Mercedes 360 Camera not working?
Common causes include missing calibration, software errors, loose connectors, or damaged cameras. The system disables itself when one or more cameras lose alignment data.
Q2. How do I recalibrate the 360 Camera?
Use a Mercedes-approved diagnostic tool such as XENTRY. Park on a level surface, clean all lenses, and follow the guided calibration procedure for each camera.
Q3. Can dirty lenses trigger a 360-camera fault?
Yes. Dirt, snow, or insect residue can block the camera view, prompting system errors. Always clean lenses before assuming electrical failure.
Q4. How much does 360-camera calibration cost?
Calibration typically costs $100–$300. If a camera module or harness is defective, repairs may reach $500–$1,000+.
Q5. Is it safe to drive with the 360 Camera not working?
While the vehicle remains drivable, you lose visual assistance in tight spaces or parking. Prompt repair is recommended to maintain full safety functionality.
Q6. Can software updates prevent future faults?
Yes. Keeping your vehicle’s software current helps prevent calibration data corruption and improves camera synchronization.
