How to manually reset the maintenance light for the 2021 Haval H6?

Is it better to maintain your car at a 4S shop or outside?

For maintenance and repairs, it is advisable to choose a 4S shop as it offers better after-sales service. For vehicles out of warranty, maintenance and repairs can be done outside at a lower cost. However, it is recommended to replace transmission oil, differential oil, and fuel filters at a 4S shop for better assurance. Advantages and disadvantages of 4S shops and repair shops: 1. 4S shops: They are more professional and can comprehensively address issues, but they may suggest replacing entire parts for minor problems. 2. Repair shops: They are cheaper and have more experience with minor issues. They often specialize in certain car models, ensuring a certain level of professionalism and offering relatively official solutions. However, their skill levels vary, and they may lack the expertise for certain cars and necessary professional equipment, resulting in poor after-sales service.

How to flash the engine ECU?

Flashing the engine ECU can be done in the following ways: 1. Write-in modification: This method retains the original ECU hardware and loads new data into the factory ECU. Write-in ECUs, also known as rewritten ECUs, are somewhat similar to flashing a mobile phone. The operation is simple and only requires a computer to complete, making it a relatively common method for flashing ECUs. 2. Replacement modification: This involves directly replacing the factory ECU with a full-time replacement ECU. This type of modification is usually seen in racing scenarios and is not popular in the market. Composition of the ECU: The ECU is a component composed of input/output interfaces, a microprocessor, analog-to-digital converters, and memory units, used to manage the vehicle's operation. The memory unit, in particular, acts like the human brain, recording many of the vehicle's data files.

When Should the Transmission Fluid Be Changed?

Different types of transmissions have vastly different maintenance intervals. Manual transmissions using mineral oil require a fluid change every 2-3 years or 40,000-60,000 kilometers, while those using synthetic oil only need a change every 150,000-200,000 kilometers. Most automatic transmissions require a fluid change every 60,000-80,000 kilometers, with only a few models labeled as maintenance-free. Typically, automatic transmission fluid should be changed every 3-4 years or when the mileage reaches 60,000-80,000 kilometers. Dry dual-clutch transmissions share the same structure as manual transmissions and also use synthetic transmission fluid, with a lifespan exceeding 200,000 kilometers, essentially making them maintenance-free. Wet dual-clutch transmissions require a fluid and filter change every 60,000 kilometers, while CVT transmissions need a fluid change every 80,000-100,000 kilometers. During the replacement process, it is crucial to note that transmission fluids of different brands and models cannot be mixed. If you want to switch to another brand of transmission fluid, you must completely drain the original fluid before adding the new brand to avoid significant damage to the transmission. Automotive transmissions are generally divided into two types: manual and automatic. The replacement cycles for their respective transmission fluids are as follows: For manual transmission fluid, it is recommended to inspect every 10,000-15,000 kilometers and replace every 50,000-80,000 kilometers under normal conditions. For automatic transmission fluid, inspect every 10,000-15,000 kilometers and replace every 60,000-80,000 kilometers under normal conditions. Hazards of long-term failure to change transmission fluid: If transmission fluid is not changed for a long time, the vehicle may experience delayed starts when cold. Prolonged failure to change transmission fluid can cause the fluid to thicken, potentially blocking the transmission cooler, leading to overheating, increased wear, and in severe cases, damage to internal transmission components. Long-term neglect of transmission fluid changes may result in slight slipping sensations during driving. Precautions for changing transmission fluid: It is best to have automatic transmission fluid changed at a 4S shop to avoid potential damage from unqualified repair shops. Never use inferior transmission fluid: Low-quality or counterfeit fluids have poor heat resistance, oxidize easily, and can form sludge or debris, clogging filters and reducing fluid pressure. This significantly affects shift quality, may cause air pockets leading to unstable pressure, and damages friction materials, seals, and metal parts, ultimately causing transmission malfunction.

How to Read an Automotive Air Conditioning Gauge?

There are two gauges for automotive air conditioning systems: the red one is the high-pressure gauge, and the blue one is the low-pressure gauge. The units on the gauges may be in bar and kilopascal (kPa), or pounds per square inch (psi). The conversion formula is: 1 bar = 100 kPa = 14.5 psi. Here are specific details about automotive air conditioning gauges: 1. Insufficient Refrigerant: When the automotive air conditioning pressure gauge shows low pressure on both the low and high sides, it indicates insufficient refrigerant, which is a common issue. Older vehicles may experience refrigerant leakage. After inspection, the problem can be resolved by simply recharging the refrigerant. 2. Expansion Valve Malfunction: When the automotive air conditioning pressure gauge shows high pressure on both the low and high sides, it indicates a stuck-open expansion valve. Poor cooling performance with both low and high pressures elevated suggests the expansion valve may be stuck open, allowing air into the refrigeration system and mixing high and low pressures, resulting in reduced cooling efficiency. Replacing the expansion valve can resolve this issue.
