If you’re facing the frustrating issue of all cameras not working in your Changan Oshan X7, accompanied by a signal error, this guide will help you resolve it quickly. While this problem can stem from electrical glitches, sensor malfunctions, or software hiccups, we’ve distilled the solution into one easy step backed by insights from Oshan X7 owners and technical experts.Why Do the Cameras Fail? Common Causes The Oshan X7’s advanced camera system, including the 360-degree panoramic view (standard in the FutureSense variant), relies on seamless integration with the car’s electrical and sensor networks. Common triggers for
| Camera Failures Include |
1.Electrical Glitches:
Temporary power disruptions to the Human-Machine Interface (HMI) or infotainment system.
2.Sensor Malfunctions:
Faulty wheel speed sensors or radar systems impacting safety features like the 360 camera.
3.Software Bugs:
Outdated firmware causing compatibility issues. Owners of pre-facelift models (2022 or earlier) report more frequent camera issues, while newer 2023–2025 models have improved camera reliability.
Hard Reset the Electrical System
Step 1: Disconnect the Car Battery
1.Turn off the engine and remove the key/fob.
2.Open the hood and locate the battery.
3.Use a wrench to disconnect the negative terminal (black cable) for 10–15 minutes.
4.Reconnect the terminal and start the car.
Why This Works:
A hard reset clears temporary electrical faults and reboots the HMI, which controls the camera system. Many users report restored camera functionality after this step.

Next Steps
1.Check for Software Updates:
Visit a Changan dealership to ensure your HMI firmware is up-to-date. Newer models often receive over-the-air updates.
