The engines of today are smaller and much more efficient, reliable and complicated than the ones mechanics faced in the past. as time passed, the mechanics who keep our vehicles operating safely needed to shift their focus to turning wrenches, and instead take advantage of computers instead. Electronic control systems to diagnostic OBD2 scanners The modern mechanic is becoming less oily than previously, and mechanical problems result in software glitches and electronic issues. With the first coast-to-coast autonomous Delphi Audi showing us what the future will bring, things are getting increasingly "techy" for the modern mechanic. As technology advances, as do the training courses that are required to ASE Certified technicians. With computer-based diagnostics training being in the forefront. However, suspension components remain mechanical and metal catalytic converters are still blocked in years, while rotors melt, causing pads to be burned when they wiggle when they com
