I replaced the TOF cable on a neighbor's drone. When powered on, it could fly without any errors, successfully avoiding obstacles and returning autonomously. However, on another day, when we tried to power it on for flight, it couldn't take off. It displayed a red error stating "Vision sensor error 16200202." Everything else is functional; it powers on, the camera works perfectly, and IMU, gimbal sensors, etc., calibrate correctly. The issue seems to be isolated to this error.

I've read in some forums that DJI might intentionally trigger this error to necessitate a full repair through their system. Unfortunately, I can't send it for repair because I don't have the time to wait for that process.

Can you advise on what can be done?

the drone is dji mavic 3 pro .
