Bus air conditioner diagnostics requires a complex engineering phase integrating data flow analysis, system interaction logic, and vehicle network communication. The 2025 “Commercial Vehicle Intelligent Diagnostic Technology Development Report” clearly points out that the core of successful diagnosis lies in following a reverse reasoning path “from system to component, from data to physical,” rather than […]
Bus AC evaporator coil is the core of the heat exchange in a bus air conditioning system, and its performance directly determines cooling efficiency, energy consumption, and air quality. Its failure modes are insidious and far-reaching, extending far beyond a simple “no cooling” issue. An article published in the 2025 issue of the journal *Automotive […]
