How to Adjust When the Rearview Camera Has No Signal?
2 Answers
When the car is just started, it may interfere with the operation of the rearview camera. You can try restarting to see the situation. It could be electromagnetic interference from other electrical devices in the car. Try turning off the radio or music player before starting again. If the issue lies with the camera itself, it may need to be repaired or replaced.
When the reversing camera shows no signal, my first reaction is to check if the camera lens is covered by dirt or mud, which is the most common issue. Gently wiping the lens usually solves it. Next, I inspect the wiring connections, such as whether the camera connector near the trunk is loose or water-damaged. I push the plug to see if it makes any noise or check if the wiring under the car is worn out, causing a short circuit. The fuse is also worth checking—locate the reversing camera fuse in the fuse box, and if it’s blown, replace it with a new one (costing just a few cents). System issues can also be a factor, so I try restarting the car after turning it off, as minor software glitches sometimes require a reset. If none of these steps work, the camera itself might be faulty and need replacement. To avoid risks while reversing, it’s best to park safely and visit a repair shop promptly, especially since nighttime reversing heavily relies on it for safety.
