In the market, there are a variety of professional diagnostic car scanners, such that deciding on the one that will give you the ultimate experience becomes quite a challenge.

Here is a review of the models which are most popular. Read on and get to know if the devices actually perform by the high expectations the manufacturer has set for them.

Factors to Look out for in a Professional Diagnostic auto Scanner

As is the norm with everything else, you can’t just buy a professional automotive diagnostic scanner without knowing what features to look out for and expect to get it right. If you do that then be prepared for disappointments. You need to have the features discussed below at your fingertips when buying a diagnostic scanner.

  • Should have the capability to detect any faults in the systems of the car, for instance, the brake systems and airbags as well as resetting them. This can be indicated in the form of problem codes. The diagnostic auto scanner should have auto code reader capabilities.
  • Data storage: The best diagnostic scanner should have a device that saves information from the car’s systems so that you can view it when there is a need.
  • Capability to print: Having information in hard copy form is an advantage and so your scanner should send information to the printer to produce hard copies.
  • Ability to show live data: An ideal scanner should display information about the performance of the car's systems on screen.
  • Ease of use: A scanner that has a simple design makes it easy for you to use. Ease in installation as well as ease of viewing information on your car’s system makes it easy for you as a driver to monitor your car’s functionality.
  • Affordability: There are simple professional diagnostic scanners which will only detect the problem and give you no additional information. We also have complex scanners which will show descriptions on the issue at hand. If you cannot afford to purchase your own, hiring or borrowing is also an option, either from a relative or friend or from the auto repair shop in the neighborhood.
  • The feature of inspection and maintenance readiness: This is a very crucial feature especially in the US where your car has to pass emission inspection at various intervals successfully.

For What Purposes Do You Buy a Diagnostic Auto Scanner for Your Car?

When you purchase a second-hand car, no seller would be willing to tell you the shortcomings of the car, and I am so sure you would also be nervous about the ordeal you are likely to go through if you did not detect a fault before buying the car.

This is a situation where a professional diagnostic scanner comes in handy. With its aid, you will get to know the underlying faults and fix them to avoid greater problems from emerging. Trust me; this will save you some money. You can choose to fix the problem or better; you can seek professional expertise.

Owning a diagnostic car scanner is better compared to using that of the mechanics since they will always charge you every other time they run a diagnostic scan on your vehicle. The costs, when added up, will be more than what you would have paid to buy an automotive scan tool.

Functioning of a Diagnostic Scanner

For a diagnostic scanner to function effectively, you need to fix it by plugging it into your car’s data output port. Most of the cars, especially those which were manufactured from the year 1996 onwards, have a 16-pin which allows you to fix a diagnostic scanner. The ports are at a position close to the steering wheel. This lets you have control even at the comfort of the driver’s seat.

The automotive scanner will indicate whether you can confidently continue driving or whether there is any fault in any of your car’s systems. Plugging in the scanner to a computer will give you specific details on the problem your vehicle’s system could be having and an estimate of how much you will have to pay for the repairs. Fully armed with such information, you can make a decision on whether to tow your vehicle to the nearest auto shop or whether to save it for another day.

Most vehicles are advanced, such that if there is a fault with any of the systems of the car, a light flashes as a warning on the dashboard. This happens since there are computer systems which manage all the internal systems of the vehicle. The signals can appear from something as minor as a faulty gas cap to a serious issue like a faulty engine catalytic converter.

Faults a Car Diagnostic Scanner can detect

Each and every set of faults a diagnostic scanner can detect is identified by its own DTC. Here are the several problems:

These are the faults which deal with sensors of the carburetor, the exhaust as well as the intake of the engine. If a problem occurs relating to the sensor of mass air flow, the sensor of the oil temperature, the sensor of the fuel pressure as well as that of the oxygen sensor, one of these codes is used to label it.

These codes are of the second set. They show problems related to the combustion cylinders of the engine. The malfunction could be affecting the fuel injector, injection pump, position sensors, throttle or the combustion cylinders.

These are the third set of codes which detect issues relating to the ignition system as well as the engine output system. The common problems are associated with the ignition coils, timing chain, camshaft or the crankshaft.

These codes are in the fourth set, and they are concerned majorly with the exhaust system as well as control of the emissions. This includes faults such as the presence of water vapor within the catalytic converter, too much pressure than normal in the exhaust system and faulty control systems of the control systems. Overheating is also denoted by these codes.

This fifth set focuses on faults of the electrical system, for instance: a faulty fuse box, control system, cruise control, and the power steering.
