In the past, cars were relatively simple machines; today, however, they are full of electronic components which monitor and govern their operation, improving efficiency and signaling you when something is wrong. This means that engine mechanics have also had to change the way they examine and repair cars. When you take your vehicle in for repairs, your mechanic will likely recommend a computer diagnostics check to help find the root of the problem.

How Do Computer Diagnostics Work?

Your car’s internal computer receives data about every component of the system and how it’s operating. If this data falls outside of a certain normal range, the car registers that there is something wrong with that circuit. It doesn’t necessarily mean that the part itself is the problem; it could be that there’s a problem with the relevant sensor or another issue in the area which is causing the abnormal behavior. However, it’s a place to start looking. Your mechanic can access this data to help find the source of the issue.

What Is the Computer Diagnostics Process?

To access the data, your auto repair technician will hook a diagnostic tool up to your car’s system, usually under the instrument panel on the driver’s side. This tool displays any diagnostic trouble codes (DTC) the system has registered. Based on the DTCs which have been registered, the mechanic then performs additional tests to get the full story and pinpoint the damaged part or system. If none of the parts are damaged, your mechanic will then look at the sensor and circuits which reported an issue, as they may be malfunctioning.
