It is necessary to clear fault codes for vehicle inspection. The following is relevant information about automotive fault codes: Definition: Automotive fault codes are codes generated by the vehicle's computer ECU after analyzing a malfunction. Common fault codes are usually caused by sensor failures or poor sensor performance. However, some mechanical faults cannot be detected by the ECU. While the vehicle dashboard may display basic fault indicators, these represent only a small portion of issues. The main diagnostics require specialized equipment - a code reader. There are various types of code readers available, such as X-431 and KT300, but they all work on the same principle and detect the same types of faults. Classification: Fault codes are categorized as current codes, history codes, and intermittent codes. Current codes are easy to detect, history codes refer to previously unresolved faults as the name suggests, while intermittent fault codes are not consistently present.

What Causes Steering Wheel Shaking?

The causes of steering wheel shaking are: 1. Inaccurate four-wheel alignment data; 2. Wheel balance issues. After tires are mounted on the rims, certain parts of the wheel may be heavier while others are lighter, causing vibrations when the wheels rotate at high speeds. All four wheels of a car have alignment data, as they are not simply perpendicular to the ground. It is recommended to perform regular four-wheel alignments. If the steering wheel shakes when driving at speeds between 80 to 90 km/h but returns to normal above 90 km/h, this is often caused by deformation or issues in the vehicle's drivetrain. In such cases, check whether the front wheel alignment angles and toe-in meet specifications—adjust if necessary. Lift the front axle and rotate the wheels to inspect their static balance and whether the tires are excessively deformed. Replace the tires if deformation is detected.

What causes the ABS light to come on during a vehicle inspection?

The reasons for the ABS light coming on during a vehicle inspection are: 1. Air in the system pipelines; 2. Malfunction of the system computer; 3. Faulty wheel speed sensor; 4. Broken ABS wiring harness. If there is air in the ABS system pipelines, it will severely interfere with the regulation of dynamic pressure, causing the ABS system to lose functionality. If the computer malfunctions, the ABS will not operate properly. The activation and deactivation of ABS rely on the wheel speed sensor transmitting signals to the computer. If the wheel speed sensor fails, the ABS will inevitably not function correctly. Dirty sensor connectors or incorrect air gaps in the sensor can also lead to poor sensor performance. For example, if the sensing part of the ABS wheel speed sensor is covered by dirt, mud, or other contaminants, it will affect the sensor's ability to detect the corresponding speed signal.

Do Cars Need Fire Extinguishers?

Cars should be equipped with fire extinguishers. Although there are no mandatory requirements for private vehicles to carry fire extinguishers, high temperatures, vehicle malfunctions, and short circuits can easily lead to spontaneous combustion. Having a fire extinguisher in the car can effectively ensure personal safety. Below are detailed guidelines: 1. Regulations: Medium and large passenger vehicles, as well as hazardous goods transport vehicles, must be equipped with valid fire extinguishers and firefighting equipment. Failure to comply may result in warnings or fines. During annual vehicle inspections, a fire extinguisher must be present in the car; otherwise, the inspection will not pass. 2. Choosing a Fire Extinguisher: Dry powder and water-based fire extinguishers are recommended for vehicles. Dry powder extinguishers are fast, effective, affordable, and widely applicable. Water-based extinguishers are further divided into water-type, foam-type, and mist-type, offering advantages such as no dust, anti-suffocation, effective fire suppression, and being non-toxic and environmentally friendly.
