Since 2010, the sales of commercial vehicles in China have experienced explosive growth, reaching 4.3041 million units, and continuing to exceed one million units for two consecutive years by 2018. The steady increase in the ownership of commercial vehicles and the improving market environment have injected a strong boost into the development of the commercial vehicle aftermarket! As the most critical link in the commercial vehicle aftermarket, diagnostic equipment undoubtedly occupies a significant share in the market.
Currently, Yuan Zheng’s commercial vehicle diagnostic equipment holds a significant position in the automotive aftermarket, thanks to the powerful capabilities of its commercial vehicle software. Yuan Zheng has been increasing its R&D efforts, with the commercial vehicle R&D team now exceeding one hundred people. The software supports diagnostics for over 150 vehicle models, covering domestic models’ engines, ECU flashing, exhaust aftertreatment, and ABS systems. The wide coverage of vehicle systems and high testing accuracy are unique advantages that drive the sales growth of commercial vehicle diagnostic equipment.
