The appearance of a yellow exclamation mark is due to the absence of a reversing camera signal, so you can check the reversing camera and its wiring. Here are some related introductions about the reversing camera: 1. Solution to the triangle exclamation mark in the reversing camera: The appearance of a yellow exclamation mark is due to the absence of a reversing camera signal, so you can check the reversing camera and its wiring. 2. The role of the reversing camera: The system makes the situation behind the car more intuitive and clear when reversing, which is one of the very practical configurations for reversing safety. When the reverse gear is engaged, the system will automatically activate the high-definition reversing camera located at the rear of the car, clearly displaying the situation behind the car on the reversing LCD screen, accurately grasping the road conditions behind, making reversing as easy and confident as moving forward.
Once after washing my car, I noticed a triangular exclamation mark appeared on the reversing camera display. At first, I thought the system was faulty. Actually, the most practical first step is to check the camera—mud spots or rain residue can interfere with the image. Last week when helping my neighbor with his car, simply wiping the lens clean with a wet wipe solved the issue. If the warning light persists after cleaning, you should check under the car to see if the wiring harness connector is loose. Frequent driving on bumpy roads can cause wires to come loose; just plug them back in firmly. Car cameras are prone to water damage, and rainy days can lead to short circuits and error reports. In such cases, it's best to unplug the connector, dry off any moisture, and then reconnect it. Poorly routed wiring in aftermarket systems can also wear out and cause false alarms, so older cars with modifications need special attention to wiring. If you really can't fix it yourself, just take it to a repair shop to check the fault codes with a diagnostic tool to avoid damaging clips by tinkering unnecessarily. The key is not to be intimidated by this little triangle—most of the time, you can handle it with some DIY effort.
