Why does a large F appear on the HOWO dashboard?

[LeKhloe]

The reason for a large F appearing on the HOWO dashboard is that the coolant level is too low. Below is relevant information about automobiles: Definition of an automobile: According to the latest national standard in China, "Terms and Definitions of Automobiles and Trailers" (GB/T3730.1—2001), an automobile is defined as a non-track vehicle powered by an engine, with four or more wheels, primarily used for transporting people and/or goods; towing vehicles that carry people and/or goods; or for special purposes. Introduction to domestic automobile brands: Domestic automobile brands include Hongqi, Changan, Great Wall, Chery, Geely, Roewe, BYD, etc.

I've encountered this situation before - a big 'F' suddenly appeared on the dashboard while driving a long-haul truck, which gave me quite a scare. This usually indicates a generator issue. If the generator fails, the battery won't charge, and the vehicle may suddenly stall, which is very dangerous. I recommend stopping to check the battery voltmeter first. If the reading is low, contact a repair station immediately. It could be caused by a loose belt or poor generator wiring connection leading to a short circuit. Remember to maintain generator components regularly, and always monitor the temperature gauge while driving - overheating can also trigger such failures. Address the issue early to avoid breaking down midway, which would waste both time and effort.

I noticed the dashboard displaying a big F, and my first thought was a fuel system issue. For those of us who frequently drive trucks, this could indicate a clogged fuel filter or a problem with the fuel pump. Too much debris in the fuel tank can affect fuel supply, causing engine shaking or stalling. When I encounter this situation, I usually try adding some fuel cleaner at the gas station. If that doesn’t work, I’ll take it to a professional shop for cleaning. Don’t ignore it, or you might face more serious issues like fuel line ruptures on the highway. Regularly replacing the fuel filter can prevent this. Be extra cautious with older vehicles, as this directly affects fuel consumption and performance.

As someone who has been driving for many years, I feel that if a big F appears on the dashboard, it's likely that the engine control unit is malfunctioning. When the ECU detects an error code, it lights up the warning light, indicating a problem with a sensor, such as an abnormal oxygen sensor or a false alarm from the ignition system. I would immediately turn off the engine and restart it to see if the warning disappears. If it persists, I would take the car for repair as soon as possible. Delaying repairs may affect exhaust emissions and fuel consumption. Pay attention to regular engine maintenance, avoid using low-quality fuel, and reduce the occurrence of such sudden issues. For safety reasons, slow down and drive cautiously when the warning light is on.
