Still, the dealer has to get the work done; so, inexperienced mechanics are put to work on problems they do not understand and really do not want to do. Who bears the brunt of their lack of training, aptitude, and attitude? Right again, the long-suffering consumer.
There is a nationwide shortage of trained mechanics, so severe that dealers and repair shops recruit from prisons in the Midwest. None of these conditions bode well for the consumer.
Every microprocessor in the modern automobile has multiple sensor inputs. Sensors measure things like engine temperature, rpm, vehicle speed, and so on. Sensors may be variable, collecting changing values, like vehicle speed, which the computer uses to make decisions, or they may be looking at the output of switches that are simply on or off. |
The Engine Control Computer may be connected to fifty or more of these microprocessors and hundreds of sensors. Nevertheless, very few of these sensors, if defective, will produce one isolated fault code. The failure of these sensors to operate properly at the proper time can create a multitude of hard-to-diagnose problems. Some of these problems present a serious safety hazard to the owner.
When the brain of a vehicle is defective, its effects may be seen throughout the body of the vehicle.
It’s not a simple thing when the brain of a vehicle, or a human, is defective. Like a cancer, it spreads out into other systems and affects them in unpredictable ways. It is a tough situation, and manufacturers and dealerships do not improve it by denying that such problems exist.
