What does the exclamation mark in Cadillac's reversing camera mean?

There are five scenarios when an exclamation mark appears on the car dashboard, namely general faults, automatic transmission faults, braking system faults, abnormal tire pressure, and lighting faults. The following is a detailed analysis of these five scenarios: General faults: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault in the general performance or components and functions of the car. Mainly includes parking sensor faults, fuel cut-off system intervention or faults, external light faults, engine oil pressure sensor faults, etc. It is necessary to go to a 4S shop for inspection to identify the source of the fault. Automatic transmission faults: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating that there is a fault in the transmission or the transmission lubricating oil is below the normal range. The transmission oil needs to be replaced in time. Braking system faults: An exclamation mark in the middle of a circle with brackets. This represents a warning of the braking system, mainly including faults in the braking system and low brake fluid level. It is necessary to immediately inspect the braking system to avoid accidents. Abnormal tire pressure: An exclamation mark in the middle of a horizontal line under brackets. This represents the tire pressure monitoring warning light. When the tire pressure of the car is too low, this warning light will light up. It is necessary to check the tire pressure of the car and restore the tire pressure to the normal range. Lighting faults: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating that there is a fault in the car lights. Solution: Go to a 4S shop for inspection and treatment as soon as possible, or you can also check it yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting, to see where the problem is.
Recently, my Cadillac also displayed an exclamation mark on the reverse camera, which usually indicates the system has detected a fault. The most common cause is the camera lens being covered by dust or mud, resulting in unclear images that trigger the warning. It could also be a system software error, especially more likely to occur after rain or frequent reversing. Loose wiring connections or aging sensors can also cause this issue. In short, once this warning appears, it affects reversing safety and should be addressed promptly. I usually park first, clean the camera with a soft cloth, and then restart the car to see if it resolves the issue; if not, a visit to the 4S dealership is necessary for professional diagnostics to prevent bigger hazards. For regular maintenance, it's recommended to check the camera's cleanliness monthly to reduce such troubles.
