In the past, detecting vehicle faults was a Herculean task, but since 1996, when vehicles with on-board diagnostic capabilities were launched in the United States of America and in 2001 in Europe, there has been a great improvement in problem solving. of the vehicles. However, understanding how a code reader works will help you determine if you need one or not.

It is not all the time that you will take your car to the mechanic because not as long as the check engine light shows that you have to replace something in your car. By simply running a scan check, you can decide whether to do some maintenance on your own or take it to the mechanic.

The code generally contains 5 digits, where the first digit will indicate if the problem is with the powertrain (P), the body (B), the chassis (C) or undefined (U).

However, the second digit will indicate whether the problem is generic or manufacturer specific. The third digit will show you the type of subsystem that belongs to the code and some of the subsystems are emissions management, injector circuit, ignition, vehicle speed, transmission, etc. Digits 4 and 5 will reveal the particular problem. Examples of DTC codes are P0171 which means the system is too thin, P00009 which is related to the performance of the engine position system, P0010 which is related to the camshaft position actuator circuit, among others.

Despite this, when you buy a code reader, you should try to buy it from the right provider and don't forget to ask for the manual. It is this manual that will guide you in the use of the tool because the interpretations of the codes are in it.
