What Do Car Symbols Indicate for Faults?
3 Answers
Introduction to car symbols indicating faults is as follows: 1. Engine Fault Indicator Light: It has two states and indications. One is a constant light, indicating that the engine's electronic control system has a fault; the other is flashing, indicating that the fault is still affecting certain performance of the engine (such as exhaust emissions, etc.). 2. Oil Change Indicator Light: When lit, it prompts the driver that 'the engine oil should be changed.' After changing the oil, this indicator should be reset to 'zero.' 3. Coolant Temperature Indicator Light: The coolant temperature indicator mainly displays the temperature of the coolant inside the engine. It lights up for a few seconds only during the vehicle's self-check and remains off normally. The commonly referred to 'engine boiling' means the coolant temperature exceeds the specified value, at which point driving should be paused immediately for repairs. 4. Brake Warning Light: The brake warning light is red, with a pattern of an exclamation mark '!' inside a circle. 5. Seat Belt Not Fastened Warning Light: The seat belt not fastened warning light is represented by a graphic (a diagonal seat belt across the passenger's chest). After the ignition switch is turned to ON, if the driver has not fastened the seat belt, this warning light will illuminate to remind the driver to fasten the seat belt. If the seat belt not fastened warning light does not illuminate under any circumstances, check whether the fuse is blown, the bulb is burnt out, or the line voltage meets the specified requirements.
I haven't been driving for long, and those little symbols on the dashboard always confuse me. If the engine light comes on, it could indicate an emission system issue, like a clogged catalytic converter or a faulty oxygen sensor, affecting performance and increasing exhaust emissions. A flashing battery light warns of charging failure, possibly due to a failing alternator or a dead battery. If the oil pressure light turns on, you need to add oil or check the oil pump immediately, otherwise, insufficient engine lubrication can cause overheating and wear. The ABS light signals an issue with the anti-lock braking system, compromising emergency braking safety. The tire pressure light indicates low pressure in one of the tires—inflate it before driving. Don't delay when these lights appear; pull over safely to check the manual or visit a repair shop to avoid minor issues turning into major repairs. Regular maintenance helps prevent problems before they escalate.
Having worked in car repair for twenty years, car symbols are essentially fault indicator lights. The engine light is usually related to the engine control module, with common issues such as worn spark plugs, faulty ignition coils, or intake manifold leaks, leading to high fuel consumption and poor performance. The battery light indicates a charging system problem, like a loose alternator belt or a short circuit, causing low voltage and rapid battery depletion. The oil pressure light signals a lubrication system alert, possibly due to a clogged oil filter or insufficient oil level; delaying repairs can lead to piston damage. The ABS light warns of a brake control unit malfunction, with sensor failure or debris blockage affecting brake response. It's recommended to use a diagnostic tool to scan error codes for early repairs, as ignoring them can double repair costs and waste time and effort.
