Training to become an Auto Mechanic
The cars that we love so much are becoming more and more advanced and difficult with the invention of new technology. It is not easy to locate the problem in the auto unless you know how to read the on board computer. The new machines have more intelligence thanks to the miniaturization of the computer chips.
The older cars had a series of lights that would indicate the problem. Though it would tell what part is posing the problem it would not tell the specific nature of the problem. In early 80’s, many vehicles were using Engine Control Module to control many of the engines control systems, such as fuel and ignition. In 1980 GM introduced an interface to the Engine Control Module (ECM) to read real time data to easily analyze the problem. This protocol was standardized and was required to be present on all new cars sold in the United States. Various tools are available to read the ECM ranging from simple consumer level tools to adnaced professional tools.
The on-board computer can monitor the sensors to determine whether they are working properly. It can detect a malfunction of the vehicle well in advanced by monitoring these sensors. It is necessary to understand how this On Board Diagnostics (OBD) works to fix the new cars. The purpose of OBD is to monitor various sensors in the car. When the computer system of the auto sees a problem, following things will happen. 1) A caution light on the dashboard is lit to inform the driver that a problem exists. 2) A code is sent to the on board computer. 3) The code is recorded in the computer’s memory which can later be read by the technician to diagnose the issue. The code and related data is read using tools like Hand held scanners, Computer based applications and scanners, Data loggers, Emission testers to name a few. According to a government study there are very good opportunities for people who complete formal training in mechanics. Without formal training applicants may face competition for jobs. A formal hands on training in mechanics will provide the required knowledge to use these tools.It will also help to understand, 1) Automotive technology basics 2) Fuel Emissions Systems 3) Electrical Systems 4) Diagnostics 5) Transmissions and Drive Lines
