Why would you need to invest in a diagnostic code scanner for your home garage? If you own a car, you need to do whatever it takes to keep it on the road with reasonable maintenance costs. The more time and trouble it takes to find out what is wrong with your car, the more expense you are racking up before you even pay for a single part or the labor to install it. If you are already reasonably sure of what is wrong with your car, you can make the tough decisions.
Here is a scenario that puts it all into proper perspective: Your car starts acting funny, it starts making strange noises. Warning lights on the dashboard panel might light up, but not always. Even when they do light up, they are not always a reliable, foolproof way of knowing what is wrong with the car.

You take it to the local mechanic who charges you for the diagnostic testing itself and then gives you an estimate of what the cost to repair this car will be. During the repairs, something else is discovered to be bad and will need to be repaired as well. You decide that the cost is going to be more than your budget will allow and the car is towed home. You could have saved the time and money but running your own diagnostic scan and then getting an idea of what repairs would cost before you even go to a mechanic. Unfortunately, most mechanics start charging from the moment they pop your car’s hood, and the cost for consultation and labor can really start piling on.
There are some limitations to the diagnostic code scanners, of course, including the brands and model years that they will work on. Because they have to be able to communicate with the car’s on-board computer, they must be attuned to what is installed. While most car computers function in much the same way, there are some that have codes that are not read or accessed by the scanner.
It is important to buy the scanner that will work with your car. If you have an older car, you do not have an on-board computer at all so a scanner won’t help you to repair and restore a ’67 GTO, for instance. But to keep your newer model car on the road, they can prove to be a very valuable tool. Using a diagnostic code scanner to get an idea of what is going on with your car before you see a mechanic can save you big money as well as time.
