What is the method for identifying car dashboard warning lights?
2 Answers
Car dashboard warning lights may illuminate due to parking sensor failure, excessively worn brake pads, engine oil pressure sensor malfunction, insufficient brake fluid, fuel cutoff system intervention or failure, etc. The identification methods are as follows: A triangle with an exclamation mark in the middle indicates a general fault warning light, which may illuminate under the following circumstances: Overheating of the dry dual-clutch transmission clutch. Fuel cutoff system intervention or malfunction. Parking sensor failure. External light malfunction. Engine oil pressure sensor failure. Traction control system warning or failure. A circle with an exclamation mark in the middle and parentheses around it indicates a brake system warning light, which may illuminate under the following conditions: In some vehicles, it lights up for a few seconds when the ignition is turned on and turns off after the engine starts. It lights up when the handbrake is engaged and turns off when released. It lights up during driving if the brake fluid level is too low. It lights up when there is a brake system malfunction. A horizontal line with an exclamation mark in the middle and parentheses below it indicates a tire pressure monitoring warning light, which lights up when the pressure in one of the vehicle's tires is too low.
The other day on the highway, a yellow engine light suddenly popped up on my dashboard, scaring me into slowing down immediately. Actually, there are tricks to identifying car warning lights: red lights indicate the highest danger level, like the coolant temperature warning or oil pressure light—you must stop immediately when you see these; yellow lights are medium warnings, such as the check engine light or ABS light, allowing short-distance low-speed driving to a repair shop; green and blue lights are usually function indicators. Don’t panic if you can’t recognize the icons—80% of car models have a small button under the steering wheel. Hold it for a few seconds, and the onboard computer display will show the fault code in English. Snap a photo of the dashboard with your phone and send it to the 4S shop’s after-sales guy—they’ll surely explain it. In a real pinch, flip through that dusty vehicle manual in the glove compartment—the last chapter definitely has illustrated explanations. Remember, a yellow light can wait a couple of days, but never push your luck with a red light.
