1. Vehicle detection is an inspection to determine the technical condition or working ability of the vehicle.
2. During the use of automobiles, with the extension of service time (or the increase of driving mileage), their parts gradually wear, corrode, deform, age, and the lubricating oil deteriorates, resulting in larger clearance of mating pairs, resulting in loose movement, vibration, noise, air leakage, water leakage, oil leakage, etc., resulting in the decline of automobile technical performance.
3. The core of automobile maintenance operation (or automobile maintenance operation) is to "maintain" the technical condition of the automobile.
