What are the reasons for chassis restrictions?

[ErinLee]

The main reasons for chassis restrictions include damage or failure of the height sensor; damage or air leakage in the air shock absorber; damage to the air compressor; VDP control program malfunction; damage or air leakage in the accumulator; damage or sticking of the air distribution valve; and air leakage in the air pipelines. The relevant introduction to the chassis is as follows: Components of the chassis: The automobile chassis consists of four parts: the transmission system, the running system, the steering system, and the braking system. The function of the chassis is to support and install the automobile engine and its various components and assemblies, forming the overall shape of the automobile, receiving the power from the engine to make the automobile move and ensuring normal driving. Maintenance rules for the automobile chassis: To maintain the chassis in winter, thorough cleaning and rust-proof treatment of the chassis must be carried out. First, the chassis must be thoroughly cleaned. If there is excessive mud or dirt on the chassis, a degreasing cleaner should be used to wash it once to reveal the original "color" of the chassis, after which rust-proof treatment can begin.
