What does a triangle with an exclamation mark inside indicate as a fault?

[DeKatherine]

A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. Solution: It is necessary to visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in vehicles. Apart from the triangle with an exclamation mark, there are four other forms of exclamation mark indicators: a yellow gear with an exclamation mark inside, a red circle with parentheses and an exclamation mark in the middle, a yellow parentheses with a horizontal line and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four scenarios: Automatic transmission fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant below the normal range. The transmission fluid should be replaced promptly. Brake system fault: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Tire pressure anomaly: A parentheses with a horizontal line and an exclamation mark in the middle represents the tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the vehicle's tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.
