Abstract: The failure of the engine hood of a series of cars produced by a company wasonce very serious in the after-sales market, which seriously affected the normal use of the car.Some users even complained to the Aosio, which seriously damaged the company's brandimage. Combined with the working mechanism and fault handling experience of hood locksystem, this paper analyzes the root causes of faults, puts forward corresponding improvementmeasures, and gives an economical and convenient after-sales fault maintenance method. Atthe same time, the technical requirements of relevant parts are incorporated into the technicaldesign standards of hood lock system, and the performance approval test specifications aresupplemented and improved, which provides important experience feedback and designguidance for the company in the development and approval of hood lock system.
