What to Do When the Light Malfunction Indicator Comes On?
2 Answers
The illumination of the light malfunction indicator signifies a fault in the lighting system. Below are detailed explanations and solutions: 1. Cause of the Issue One: Brake System Malfunction. Solution: First, ensure the handbrake is fully released. If the light malfunction indicator remains lit after releasing the handbrake, check the brake fluid level for normalcy. 2. Cause of the Issue Two: Oil Pressure Malfunction. Solution: The oil pressure indicator can display the oil level and pressure inside the engine. If this indicator stays lit, immediately replenish the engine oil. 3. Cause of the Issue Three: Engine Overheating. Solution: The water temperature indicator shows the temperature of the coolant in the vehicle's engine. If the engine temperature is too high, promptly add coolant or purified water.
Last time I was on a long drive, a yellow bulb symbol suddenly popped up on the dashboard, and my heart skipped a beat. A lighting fault warning usually means one of the bulbs has stopped working—commonly the brake light, license plate light, or reverse light. There's no need to panic when you see a yellow warning light; you can still keep driving, but if it's red, you must pull over immediately. If you notice this at night, quickly check if your headlights are working. If the headlights are fine, turn on your hazard lights and pull over, then have a friend help inspect all exterior lights. I once had this happen due to poor contact in my taillight—using a phone to record a video for inspection is much easier than doing it alone. The bulb models are all listed in the manual, and ordering them online for a few bucks to replace yourself is simple. However, if it's the turn signal or daytime running light that's out, it's better to head to a repair shop as soon as possible.
