An automobile mechanic is a lot like a doctor - people come to them all day with their complaints and the mechanic has to figure out what the problem is and fix them. But while the human body is admittedly complex, it has remained essentially unchanged over thousands of years while car designs are updated with each passing season. The increasing complexity and sophistication of modern machines has made the automotive technician one of the more technically demanding trades. The job requires more preparation than ever before.
While vehicle manufacturers are building cars that last longer, they have simultaneously become more difficult to repair. To make cars safer, lighter and more fuel efficient, new materials such as high-strength steels, aluminum and steel-plastic have been added into vehicle bodies. Technicians can no longer assume they're working with good old steel when they start cutting or welding.
Vehicle designers must balance issues associated with ease of repair with the push towards lighter and more fuel efficient cars. General Motors began about five years ago assigning engineers from their service operation to work alongside designers and their engineers can now use a virtual hand and wrench with a digital screen to test how a new machine in the design stage will affect the mechanic's repair time OBD Tool.
Today's auto body shops feature fancy scanners, diagnostic software and lab scopes to assist the accuracy of the repair process. Modern mechanics need to diagnose sensor and computer glitches in addition to the continuous stream of new technology introduced by car makers that have to be quickly learned and mastered. Manufacturers once assumed that computerization which outputted problems to computer printouts would make repairs easier. Instead the opposite has occurred, with a variety of fuel injection systems, electric steering Car Repair Tool, variable transmission and valve timing, and sophisticated electronic systems throughout the machine requiring greater cross-function skill.
