Car Diagnostic Code Readers Designed For OBDII Autos Can Save You Money

Car Diagnostic Code Readers Designed For OBDII Autos Can Save You Money

24 Oct 2019

The OBD2 code reader is an on-board diagnostic tool used to detect vehicle faults. In times past, detecting vehicle faults was a herculean task but since 1996 when vehicles with on-board diagnosis capabilities were released in the United States of America and in 2001 in Europe, there has been great improvement in vehicle troubleshooting. However, understanding how a code reader works will help you in determining whether you need one or not.

Spending from $5.00 to $100.00 for an OBD2 Code Reader could save you hundreds of dollars in repair costs. Best of all the code readers are easy to use. The OBD2 Code Reader package has an instruction book that tells you how to use the OBD2 Code Reader and definitions for the codes.


Car diagnostic code readers have gone a long distance from what they used to be, let's talk about a some history and bring you up to the times. Auto readers, commonly known as auto scanners or OBD scan stands are devices that are hand held that are inserted into an OBD port to help identify the vehicle engine and problems associated with emissions.

When that pesky "check engine" light comes on and you take the car to the repair shop to see what the problem is, the auto mechanic will read the code and tell you that a part needs to be replaced or a repair needs to be done, depending on the code reported, when this is not always the case. The fee that the repair shop charges for this service (attaching their OBD2 code reader to a vehicle to read the code) usually is the price they paid for their OBD2 Code Reader.

It is not all the time that you will be taking your car to the mechanic because it is not every time that the display of check engine light means that you have to replace something in your car. By simply running a scan check, you can decide whether to carry out a little maintenance on your own or take it to the mechanic.


When a serial bus communication problem occurs in your vehicle, it will initiate a diagnostic trouble code (DTC) and turn on the check engine light. When you connect the code reader to the OBD port below the dashboard of your car or very close to the steering, it will read the code which will let you know what the problem is. The code generally contains 5 digits where the 1st digit will indicate whether the problem is with the powertrain (P), body (B), chassis (C) or undefined (U).

So ask yourself - "Do I want to pay the fee at the repair shop to have them read the code that made my check engine light come on? OR just get my own OBD2 Code Reader - pay for it one time and use it as many times as is necessary and save money?" Read the instruction book that comes with your OBD2 Code Reader for complete instructions.


How to use the OBD2 Reader

If your "check engine light" is on, plug the OBD2 code reader into the receptacle, typically found under the steering wheel, and refer to the code reader book to find out what the code means. We recommend that you erase the code and if the "check engine" light comes back on within a few days, with the same code then, more than likely, repairs should be done.

When the "check engine" glows red on the dashboard, we make a practice of reading the code, making a note of the code reported and erasing it from the on-board computer. Wait a day or so to make sure the "check engine" light doesn't glow red at us again which indicates a temporary situation. If the same code returns then we would resolve the situation with whatever repairs are required.

In spite of this, when you are buying a code reader, you should endeavor to purchase from the right vendor and don't forget to request for the manual. It is this manual that will guide you in using the tool because the interpretations of the codes are in it. There are different types of readers in the market with different prices, so, take your time to check the features of what you are buying.

It is advisable to purchase a reader that supports many protocols because you will be able to use it on different brands of vehicles.
