Where Can I Read Car Codes For Free?

Today, a wide variety of auto parts stores offer the possibility of reading a diagnostic code at no additional cost. So, this free service is not provided by just any auto parts store. Among the most convenient options of course are auto parts stores with great experience and good customer service. Some of them are:

1. Advance Auto Parts

2. Pep Boys

3. AutoZone

So, an employee of these stores will be in charge of making the connection between a code reader and the potential customer’s vehicle. Once the results are obtained the same employee will inform about the codes that may appear.

Of course, the employees are very accustomed and know perfectly well each of the codes that can appear for a car. That is why when a vehicle driver does not understand a code, the employee will be able to help him understand what the real problem of the vehicle is.

In the worst-case scenario, the auto parts store representative will be able to provide a distant idea about what might be going on with the vehicle. In either case, this can be very helpful for the vehicle owner to get down to business.

Reading the diagnostic code is always a great way to start troubleshooting a vehicle’s mechanics. This rules out a set of possibilities and gives better guidance to the mechanics or the vehicle owner. At the same time, the auto parts store that provides a free auto code reading usually carries a large number of spare parts.

This is the main reason why the diagnostic code reading is offered for free. Of course, the driver of a vehicle is under no obligation to purchase the necessary parts or accessories at the same auto parts store. However, after receiving this free service people end up buying from the same auto parts store to save a trip.

Along with this, if a car’s code reader has indicated some errors in the vehicle this can be supplemented if the check engine light also comes on. So, this may indicate the clear presence of some mechanical problem or some general inconvenience in the vehicle. At the same time, it is an excellent way to have more information and save approximately $50.

In some cases, it is not specifically a component or a defective part within the mechanics of the car. Simply put, it could be that the fuel tank cap is not properly in place. When this happens then the check engine light comes on until the fuel cap is located the right way.

Moreover, it is necessary to consider that some error codes in this free service may indicate only part of the whole problem. As it happens on many other occasions, a certain mechanical malfunction could produce a different error code. For example, we can take the example of an oxygen sensor failure. 

So, a free code check is only the beginning of the problem as the causes can be very different. Here it may simply be a general problem with the design of the car, and incorrectly functioning software deteriorated wiring, or a sensor with problems that prevent it from doing its job.

In any case, this free service can be a great way to get started on fixing the real problem. Sometimes, some vehicles of the same make and model that are manufactured in a given year may have the same problem in common. In this case, this is a very common situation so it is easy to check online to see if the make and model of your vehicle has a general problem.

On these occasions, manufacturers can provide a goodwill warranty because it is simply a manufacturer-recognized issue. It is also a great way to avoid the cost of repairs needed for these vehicles. The manufacturers usually take care of it, otherwise, it is very bad publicity for themselves.

However, a free comprehensive diagnostic code reading is not the only way to obtain this service. Vehicle owners also have the option of obtaining this service from a dealership or a trusted auto mechanic. Of course, in these cases, the free vehicle diagnostic code reading service is not usually offered.

On most occasions, people should have a budget of $45 which could go up to $75 on some occasions or locations. Here, the difference is that these diagnostic readings are complete and the owner gets a premium version of the same free service offered by the auto parts stores we have mentioned.

Both the dealer and the mechanic also require an OBD reader. Beyond that, this is a different service as the software used in this electronic tool is usually much more expensive, and of course sophisticated. That is why it is not a free service here, unlike what auto parts stores may offer.

In the same sense, a mechanic can offer a much more accurate diagnosis as he can also offer the complete repair of the vehicle. So, it might be much more convenient to have a complete diagnostic reading to save time in actually fixing a vehicle. 

On the other hand, the free service that auto parts stores can offer can also be an excellent option to start knowing the real problem of a vehicle. It is after all a free service that does not generate any kind of cost to the vehicle owner. However, it is always necessary to know what each of the limitations of the free service is. 

Is AutoZone Diagnostic Reliable?

Many people who have opted for free diagnostics from AutoZone auto parts stores have mentioned the major limitations of this service. In principle, it is not a service that is reliable and accurate compared to other diagnostic services available today.

When a person opts for free diagnostic verification a code scanner is usually used. This electronic device connects directly to the vehicle’s on-board computer. So, simply put this electronic tool seeks to scan and read what error codes the vehicle’s computer has recorded in recent times.

So, once the results are obtained, it is up to the driver of the vehicle to make the necessary assumptions to know where the real problem lies. In general, the results that this free service can offer are too vague and inaccurate. This is specifically because basic software is used in combination with the code scanner.

In turn, the poor accuracy is complemented by the specific design of a vehicle. When an error code is successfully detected, the problem that generates it is not a single one. On the contrary, there may be several possible faults that have occurred to obtain a certain error code.

Even the same error code could be caused by two separate problems that produce the same code. An example of this can be found in faulty spark plugs and a faulty sensor. These two different parts that are defective can generate the same error code.

So, when people repair or replace the faulty sensor the error code could still be present. Furthermore, it is very unlikely that an error code from this free service will determine precisely what the problem is. 

In turn, the moment a malfunction occurs in the mechanics of the vehicle, this can easily generate failures in other areas of the same vehicle mechanics. Of course, this cascade of mechanical problems also generates a wide variety of error codes in a free diagnostic check.

Beyond each of these limitations of AutoZone’s free diagnostic check, it is still a useful service in some sense. People here can get an idea about what is going on in the vehicle. Of course, it may be too general an idea although it will always be better to have no data at all.

Beyond that, employees who are more experienced also can correctly guess what the problem might be. Here, the experience of more senior employees is perfectly complemented by AutoZone’s free diagnostic verification service. This results in a more accurate conclusion, which is very helpful when implementing the most suitable solution.

However, people also have the possibility of getting a diagnosis in its most complete version when they pay between $45 and $75 to a professional mechanic. This can save some time in the search for the real problem.
