What Causes No Signal in the Rearview Camera?
2 Answers
The reasons for no signal in the rearview camera are: 1. The data cable connected to the rearview camera is loose or has poor contact; 2. The rearview camera is damaged; 3. A fault in the gear position sensor. The solutions for no signal in the rearview camera are: 1. Turn off the engine, remove the navigation card, reinsert it, and restart; 2. Check the wiring and the connection points installed in the vehicle; 3. Replace the power cable with a new one. The rearview camera captures real-time images of the area behind the vehicle through a rear-mounted camera and displays them on the central control screen. Drivers can observe the situation behind the vehicle based on the screen, improving parking safety.
I've been driving for a while and have encountered the issue of no signal from the reversing camera a few times. The first time it happened, I was all flustered. Generally, there are quite a few reasons: the camera itself might be damaged, like being hit by a stone or short-circuited due to water ingress; loose or broken wiring connections, especially at the corners of the trunk where they're prone to being pulled; a malfunction in the host display screen causing poor signal reception; a blown fuse—check the fuse box to see if the corresponding one is broken; or abnormal signal transmission when shifting into reverse, sometimes due to issues with the gear shift mechanism. From my own experience, the first thing to try is restarting the vehicle to see if the issue resolves. If not, open the trunk and check if the wiring connectors are secure. Remember to prevent water from entering the camera holes when washing the car regularly—preventing these small issues is crucial. Driving without a reversing camera is quite dangerous, especially for new drivers trying to park in narrow alleys where scratches are more likely. Address the issue promptly to avoid affecting daily driving safety.
