Understanding The OBD2 Codes List


An OBD2 codes list is a series of diagnostic codes that help to define the problems an automobile is experiencing. When most consumers and novice mechanics first learn about diagnostic machines, they have very basic ideas about how these things work. They tend to issue very complex readouts that professionals must learn to interpret.

These alpha-numeric combinations are used by diagnostic machines to solicit information from vehicles. Thus, they are intended to be used on vehicles that were manufactured after a certain date. In North America, these apply to all motorized vehicles that were manufactured after 1996.

A vehicle will have a special connector that can be attached to the mechanic’s scanner. This will have a clearly defined port and is typically labeled as well. During any related training sessions, these professionals will be taught to identify these hook-ups and the best ways for approaching, such as whether or not the car should be on or off during this process.


OBD stands for on-board diagnostics. Thus, this is the automobile manufacturer’s own efforts at ensuring that things can be repaired easily. You will find that these are also commonly referred to as PIDs or Parameter IDs. Hence, people can use the supplied information to learn where vehicular troubles are started and which systems they are impacting.


How Automotive Technicians Use OBD2 Codes


In the most basic sense, these codes can cut costs for both mechanics and the clients they service by significantly reducing the amount of manpower and labor that must be invested in the diagnostic process. This has become all the more important now that cars, trucks and SUVs have become complex and often computerized equipment. Many decades ago, identifying the source of an issue did not require such an involved series of systems and interactions and the process of determining these things was far less time-consuming and costly.


The technicians will need to enter the PID after having connected with the bus of the vehicle via the special connector. The bus will then recognize the PID and send back the appropriate information to the scan tool. This is then relayed to the technician so that he or she can interpret it.


The interpretation process does not take a lot of technical genius. Most scan tools are very specific and straightforward in their delivery of information. More importantly, mechanics are trained to know what this data means and what type of actions it should incite. This is why the collection of this type of data is such a vital part of running a modern automobile repair business. Unlike in years past, the requirements and needs have become far more complex and thus, require complex technical solutions.


An OBD2 codes list will ultimately be specific to the make and model that is being investigated. This is an invaluable collection of data that will help both car owners and the mechanics they use to facilitate timely repairs. More consumers are choosing to work with companies that have access to effective diagnostics machines as they know that this can significantly simplify the repair process.
