SVS indicator light is the engine fault indicator, indicating that there is a fault in the engine. After starting the engine, when the engine ECU detects a fault in the engine, the SVS light will illuminate, indicating that there is a fault in the vehicle's engine. For such engine faults, it is recommended to seek professional mechanics for handling and inspection, first checking whether it is a sensor or wiring fault. If it is an engine fault, it should be dealt with promptly. Reasons for the engine fault light to illuminate: 1. Poor fuel quality: The engine has requirements for fuel quality indicators, especially as regulations in various places impose higher demands on engines, the requirements for fuel quality indicators also increase. In real life, some gas stations cannot fully comply with regulations to provide fuel that meets the performance requirements of high-performance engines, which leads to frequent occurrences of the engine fault light illuminating. 2. Engine cylinder carbon deposits: After a certain period of use, the engine interior will inevitably accumulate some carbon deposits, which are unstable in nature and store heat. These stored heat can cause disorderly ignition in the engine, leading to engine knocking. In such cases, the engine fault light will illuminate.

When I saw the SVS light illuminate on the Futian Tunland, my first thought was that it indicated an issue with the vehicle service system. It's a common warning light, signaling that the vehicle may require urgent maintenance or inspection—perhaps the engine oil has degraded, there's a fault in the emissions system, or a sensor isn't functioning properly. Once, during a long drive, this light came on, and it turned out to be a clogged air filter causing insufficient engine airflow; cleaning it promptly resolved the issue. Ignoring it can allow minor problems to escalate, affecting fuel efficiency or causing further component damage, leading to higher repair costs. I recommend stopping immediately to check the owner's manual for specific error codes, using a basic diagnostic tool if necessary to read the fault codes, and driving at low speed to the nearest service center—avoid risking a high-speed drive. Developing a habit of regular maintenance, such as checking engine oil and filters, can significantly reduce such unexpected occurrences.

When the SVS light flashes on the dashboard, my heart skips a beat, as it often indicates an urgent issue requiring attention in the vehicle's system. On the Foton Tunland, it could be related to engine control or emissions, such as a faulty catalytic converter, malfunctioning oxygen sensor, or a short circuit. I remember a time when I ignored this warning, and it led to worsened engine performance and costly repairs. Now, whenever the light comes on, I slow down and pull over, checking the manual for solutions. If I don’t understand the issue, I promptly call for a tow truck to take the vehicle to a professional shop for inspection. Don’t underestimate this light—it can warn of safety hazards, like excessive emissions affecting health. Responding promptly protects both the car and your wallet, ensuring a safer journey.

What is the reason why the dashboard door light is always on?

When the dashboard door light is always on, it indicates that the door is not properly closed. The door has two locks; if you close it gently, only the first lock is engaged. If you don't close it firmly, the indicator light will remain on. Here is some relevant information about car doors: 1. Design requirements: Ensure ease of entry and exit for passengers, with the maximum opening angle controlled at around 65° to 70°. During the opening process, the door should not interfere with other parts. When closed, the door must be securely locked to prevent it from opening while driving. 2. Definition: The car door provides access for the driver and passengers, isolates external interference, reduces side impacts to some extent, and protects the occupants. The aesthetics of the car are also related to the design of the door.

What does a triangle with an exclamation mark in a car mean?

A triangle with an exclamation mark inside indicates a malfunction in the car's regular 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 cars. Besides 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 horizontal line with parentheses and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four situations: Automatic transmission fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant below the normal range. The transmission oil should be replaced promptly. Braking system fault: A circle with parentheses and an exclamation mark in the middle represents a braking system warning, mainly indicating a braking system malfunction or low brake fluid level. The braking system should be inspected immediately to avoid accidents. Tire pressure anomaly: A horizontal line with parentheses and an exclamation mark in the middle represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark is the lighting fault indicator, indicating a malfunction in one of the car's lights. Solution: Visit a 4S shop as soon as possible for inspection and repair, or check yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.
