What is the reason for the reversing light not working and the reversing camera not displaying?
4 Answers
Reversing light not working and reversing camera not displaying is due to a damaged reversing light fuse. Here is a detailed introduction to reversing lights: Function: Reversing lights are installed at the rear of the vehicle to illuminate the road behind during reversing and to alert vehicles and pedestrians behind. Installation instructions: Vehicles less than 6 meters in length are required to have one reversing light installed, with an option to install an additional one. Typically, the left fog light and right reversing light are used because the driver's seat is on the left, making it easier to observe vehicles ahead with the fog light on the left; while the reversing light on the right facilitates the driver in reversing and parking on the right side of the road at night.
I've encountered this issue myself. When both the reverse lights and camera aren't working, it's usually not an independent failure but rather a shared core component malfunction. For example, a blown fuse—reverse systems typically have a dedicated fuse in the vehicle's fuse box, and if it fails, the current is cut off. Another possibility is the reverse switch located near the transmission, which detects whether the car is in reverse gear. If the switch is stuck or the wiring is loose, the entire system will stop working. Additionally, a faulty control module or relay, which manages the reverse signal transmission, can cause both the lights and camera to malfunction when they age. When troubleshooting, proceed step by step: first check if the fuse is blown, then manually shift gears and listen for a click to determine if the switch is functioning. If you're inexperienced, avoid tampering with the wiring harness—it's safer to have a repair shop inspect it. Modern cars have complex electronic systems, and software issues could also be the culprit, but I recommend starting with basic troubleshooting.
When I was reversing, I noticed the lights weren't on and the screen went black, which gave me a scare. Later, I figured out these two issues often occur together, with the root cause lying in signal control. Most likely, it's either a faulty reverse switch or a blown fuse. The switch is hidden near the transmission, and over time, water ingress causing rust or contact wear can prevent signal transmission, rendering the system inoperative. Poor wiring connections are also a concern, as aging or loose connectors can lead to power loss or short circuits. It's best to take it to a professional shop for inspection immediately—safety first. Regular maintenance should focus on waterproofing and dust prevention, and avoid prolonged reversing to prevent excessive load. Your car is your partner; don't overlook small details that could lead to big troubles.
When the reverse lights and camera stop working simultaneously, common failure points typically include these areas: a blown fuse, which protects the circuit; a faulty reverse switch, located on the transmission to detect gear position; or loose wiring connections. If there's no response when shifting into reverse, it's mostly a switch issue. You can check the fuse box yourself, but avoid random repairs.
