How Many Categories of Automotive Repair Qualifications Are There?

1 Answers

07/30/25 8:47am
Automotive repair qualifications are divided into five levels: Junior Technician, Intermediate Technician, Senior Technician, Technician, and Senior Technician. The following are the precautions for repair work: Make Proper Markings: The components of a vehicle vary greatly in size and type, with a vast number of parts ranging from small screws to large circuit boards. Each part plays a unique role in the vehicle. Missing any piece or part can lead to unpredictable risks for the car. Therefore, during vehicle repairs, dismantled parts should be properly stored and clearly marked, especially those with specific installation directions or those that are easily confused, requiring extra attention. Use Tools Correctly: Proper use of tools is crucial in vehicle repair. The automotive repair industry generally has specialized tools that play a key role in the repair process. The correct use of these tools affects the quality of the repair. Avoid using tools roughly or forcefully, as this can damage the vehicle. Therefore, violent disassembly must be strictly avoided. Component Cleaning: Cleaning components is also part of automotive repair work, with its own set of precautions. During vehicle operation, parts accumulate a significant amount of dirt, dust, and grease, requiring thorough cleaning. There are strict regulations regarding cleaning temperatures and the solutions used. For example, some rubber products cannot be cleaned with alkaline solutions.

What Are the Reasons Why a Mazda Won't Start?

The reasons why a Mazda won't start are as follows: 1. No fuel: If the fuel gauge has dropped below the red line, the car naturally won't start. 2. Dead battery: This could be due to leaving the headlights on for a long time, resulting in a drained battery, or the battery's lifespan has expired. It is generally recommended to replace the battery every three years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause electrical circuit failures in the vehicle. Checking for a dead battery is simple—just press the horn to find out. 3. Incorrect gear position: For automatic transmission vehicles, the gear must be in P or N when starting. If it's in R or D, the car won't start. Some manual transmission cars won't start if the clutch isn't depressed. 4. Fuel quality issues: If water or mud is found in the fuel tank upon inspection, using such fuel will inevitably damage the car. Therefore, always refuel at reputable gas stations. When traveling, you can use a gauze wrap on the fuel nozzle to filter out impurities. 5. No antifreeze: Some car owners use water or low-quality antifreeze, which can freeze the entire cooling system in extremely cold winter conditions, leading to a cracked engine and a non-functional water pump, preventing the car from starting and damaging other engine components. 6. Excessive carbon buildup: This can also prevent the car from starting. The solution is to drive at high speeds regularly to reduce carbon buildup. Additionally, here's a small tip for starting the car: before turning the key to start, first turn it to the ON position, then back, and then to the START position to ignite. This allows the computer to calculate the water temperature and optimal air intake, making ignition smoother. 7. Non-human operational errors: Apart from the above human operational errors, other possible reasons include a faulty starter motor, fuel pump or injector issues, or sensor malfunctions. For these more complex situations, it's best to seek professional help to diagnose and fix the problem.

Is the Volkswagen Passat a Good Choice for a B-Segment Car?

Here is some information about the Volkswagen Passat: 1. Exterior Design: The front face maintains the traditional family-style design, but the U-shaped grille is wider, giving a more aggressive look. From the side, the new Passat appears more elongated, likely due to a lower-profile design, which enhances its elegance. The rear design remains conservative, but the lettering below the Volkswagen logo adds a touch of premium appeal. 2. Interior Design: The interior is unmistakably Volkswagen, with a strong business-oriented feel. While it may lack some technological flair, it offers a rich set of features. The dashboard incorporates carbon fiber elements, reducing weight without compromising strength. 3. Powertrain: Although specific engine details are not confirmed, the mainstream 2.0T engine is expected, as it would be unusual for a mid-to-high-end B-segment car to lack this option. However, considering the upcoming China 6 emissions standards, the 1.4T engine might become a primary focus.

What is an Automotive Fuse and What is Its Function?

Here is a related introduction to automotive fuses and their functions: 1. Function: The purpose of an automotive fuse is similar to that of a household fuse. It melts when the circuit current is abnormal and exceeds its rated current, thereby acting as a protective barrier for the circuit. Automotive fuses can be broadly divided into two types: fast-blow fuses and slow-blow fuses. 2. Classification: Commonly used automotive fuses include high-current fuses and medium-low current fuses. Generally, medium-low current fuses are more accessible. Medium-low current fuses can be roughly categorized into blade fuses (including automatic fuse boxes and mini fuses), plug-in fuses, bolt-down fuses, tube fuses, and flat fuses. Among these, the most commonly encountered are medium-sized ATO or small-sized fast-blow blade fuses. Blade fuses can carry small currents and short-duration pulse currents, such as those in headlight circuits or rear window defrosters.
