What Modern Diagnostics Demand From Independent Garages

Modern diagnostics demand far more than plugging in a tool and changing parts. In this episode of On The Ramp, we talk about what working on today’s vehicles really requires from independent garages. The conversation covers process, responsibility and decision making in a world of complex systems, EVs and ADAS. We discuss why fault codes are only the starting point, why structure and method matter, and what happens when diagnostics is rushed or handled without the right understanding. This episode is for garage owners and senior technicians who want to work safely, professionally and sustainably as vehicles continue to evolve.
