All About the Scan Tools and Electronic Control Module
While scan tools and code readers are similar in purpose and function, they can be used somewhat differently. Code readers are often a bit simpler and can be less expensive than scan tools. They are connected to the Onboard Diagnostic system on a vehicle and display code on a screen for the operator of the device. It is then up to the technician or mechanic to recognize this code and understand what it means regarding system performance. These codes are usually fairly general and indicate a particular component of the vehicle that has an issue, such as the drive train or issues with internal temperature readings.

Scan tools can be somewhat more elaborate and expensive, but also provide a technician with more thorough information. Rather than simply displaying a code, these devices often provide information to a mechanic about the location of the system problem. This means the technician does not have to read a code, and then consider where the problem has occurred, but instead simply sees the problem region indicated on the scan tool itself.
Numerous manufacturers make these different devices, and they can be acquired at a wide range of price points and store locations. In the past, using the first generation of OBD technology, such scan tools needed to be replaced fairly regularly and were typically owned only by professional mechanics. The introduction of second-generation OBD systems in 1996, however, established a standard to which all systems would adhere, allowing these devices to last longer and become more widely available. Home car enthusiasts and drivers, in general, can easily obtain a reader or scan tool to quickly run diagnostics on their vehicles and determine where problems may be occurring.
Learning to Use Scan Tools and Code Readers
Even the most advanced scanning devices only relay the information provided by the Electronic Control Module and OBD within a vehicle. Mechanics and technicians need to be able to look at this data and understand what it means regarding maintenance or repairs. Engineers often attend technical schools to learn how to read and act upon the information received through a scan tool. Knowing that there is an issue with high temperatures in the engine is only the first step in fixing car issues; understanding how to fix the problem is even more important.

Proper training and education are typically required to be able to use scan tools and run diagnostics in the most effective way possible. Those with the training to diagnose issues with vehicles often operate much like doctors, analyzing the problems that are visible and determining what is needed to fix them. While technology makes it easier for mechanical technicians to locate the source of an issue, these professionals still need to know how to isolate the specific problem and then make repairs.
Numerous schools offer online classes to help people with interest in vehicle mechanics and maintenance. While many such technicians work in general auto repair shops and garages, there is also a need for skill mechanics working on designing new cars or building and repairing professional racing vehicles. An understanding of precision engineering and mechanical design is vital to this type of work. Formal classes online or at a technical school help students learn to quickly and effectively maintain and repair a wide assortment of vehicles.
