Thinking of Buying a Car Code Reader? Think again!

Nothing is going to mess your day as much as a “check engine” light when you are headed on your way out. This leads us to an important question – are you having frequent trouble with your car, and going to the mechanic way too often?

Not sure whether it is an ignition timing issue, engine rpm levels or the air and coolant temperature? Does your mechanic look way too happy when he sees you with your repaired car? These are the times when you are going to end up frustrating yourself with the same question over and over again – what is it that is meddling with my car’s engine so frequently?

Don’t you worry, we have your back. We have the perfect tool to solve all your troubles, and this does not even call for you to have specialized in the field of mechanics.

If you have a basic understanding of a few cars related problems, we think you are going to do well.

What is it?

Have you ever heard about a car code reader? Well, it is a car-diagnostic tool, the simplest you will ever stumble upon. It has been built to interface with a car’s computer.

It diagnoses the automotive problems such as ignition timing, level of built-up in the engine, the performance of the fuel injector, firing of the ignition coils, engine rpm levels, air and coolant temperature, crankshaft and camshaft position, the throttle opening, etc.

Thus, after diagnosing and identifying the problem, it reports the trouble codes and gives us the exact issue without any details – this means that all the unnecessary details are filtered out along with a remedy which you could incorporate to better the whole problem.

This is implicative of the fact that you are going to have to seek help or you would want to study the problem thoroughly so that you can think of possible solutions for the same.

Nonetheless, a car code reader does serve to be a headstart.

How does it work you ask?

Like man, technology has come to evolve as well. It was easy to detect an error in a car which was manufactured in the past because all the mechanic had to do was turn on the car’s engine and decipher the problem on the basis of the noise that could be heard.

However, today’s cars have been equipped with computers and if a problem arises – it is bound to cost a lot.

This evolution in the auto industry was a result of stricter emission standards which required to keep a check on the social costs of using a car. Thus, computers were installed in cars, too.

This did improve the scenario concerning air pollution; however, different brands of companies had prescribed a different method of resolving an issue with the car or its computer.

There were various tools for this procedure; thus, the small shops of mechanics could not afford to buy it all. This meant that the consumers had to spend bucketloads of money.

Hereafter, a more straightforward method came into the picture wherein all the brands of the cars could be checked using the device, and this device was none other than the car code reader.
The computer has been designed in such a manner that every input corresponds to a unique output.

So if the engine control is not able to receive a range of outputs which lie in the standard operating tolerances, then the check engine light is going to flash.

This is when a car code reader would come into the picture.

It is an effortless task to use this tool, all you have to do to make it work is, plug this device into your car’s computer system, under the dashboard (in rarer cases, it may be located behind a panel in the dash, or even behind an ashtray or another compartment).

So whenever your car faces any problem, this tool identifies it and displays the “trouble code.” Therefore, this portable device hooks merely up quickly to your vehicle and it reads the trouble codes that pop up.

The engine controls are going to use the same programming language like that on the car code reader.

Thus, the screen of the car code reader is going to display the code with regard to the problem, and you can resolve the problem by running to the auto parts store – if it is feasible for you to fix the issue.

It’s benefits:

Owing a card code reader gives its owner miscellaneous benefits, a few of them are as follows:

  • It is cost efficient: it makes you save an enormous amount of money as it cuts down your visits to the mechanic. So instead of visiting the mechanic every time your check engine light turns on, and being fooled away for minor issues, one should own this tool. As this helps you detect the problem on your own and take the appropriate steps.
  • This tool is compatible across all vehicles, so it is not necessary for one to buy a new car code reader everytime they buy a new car. Plus this tool can be used multiple times, on numerous vehicles. This is a point to be noted because it is not only going to save your time but is also going to increase the utility you derive out of the car code reader multiple folds. (Note: cars and trucks built prior to 1996 require specific proprietary code readers, the newer ones use a universal code reader.)
  • It also helps you to find out whether the issue is minor or major, thus enabling you to determine the severity of the problem. Depending on the nature of the problem, you can decide on the number of ways you can resort to resolve this issue.
  • The best part about this tool is its portability. Owners of this tool can carry it whenever and wherever they want. Carrying this tool in the vehicle provides the owner with a peace of mind as the owner gets to be aware of the issue and can take it for repair according to its extremity.
  • If you depend upon using a car code reader – you will have the knowledge of issues that your car is facing. Thus, if the nature of the problem is extreme and you end up taking your car to the mechanic – the probability of making a fool of you is decimated. Thus, not only an investment in this device is going to be cheap – it is going to make sure that you have knowledge about the other significant issues as well so that you can drive the amount charged by the mechanic down – if it is not apt.

Who are they for? And is it worth using them?

This tool is an essential requirement for all the people who own a vehicle. It has grown out to become a necessity because of the increasing number of attempts the mechanics make so that they can make their way into your pocket and unload a stack of cash.
