Things to consider when purchasing an OBD2 Car Scanner – Buyer’s Guide
If you’ve never used an OBD2 car scanner before, you might have no idea what exactly you should be looking for when purchasing one. In order to make a quality purchase, there are a couple of things you must consider.
- Variety of readings – The fact of the matter is that not all car scanners are capable of scanning the same metrics. While some will give you information on just about everything you would ever want to know, others are limited when it comes to things like “time of malfunction” and coolant level.
- Portability – OBD2 car scanners come in all different shapes and sizes. Make sure that scanner you purchase can be picked up and moved around with ease.
- Data Storage – The best OBD2 scanners come with storage capabilities. This ensures that you can view all of your readings long after they’ve been taken; a valuable feature to have.
- Special features – From automatic decoding features, to WiFi connection, and more, OBD2 scanners come with a variety of special features. While these features aren’t absolutely necessary, they do serve to make your car scanner all that much more valuable.
How do you use an OBD2 car scanner?
If you’ve never used an OBD2 car scanner before, you probably have no idea what you’re doing. OBD2 scanners work by plugging into the OBD2 connector located beneath your dashboard. Once you have plugged the scanner in, you turn the key in your ignition until your car is on, but without fully starting your car’s engine.
After doing this, your scanner will ask for you to enter some information. Typical information needed includes your car’s VIN number, its make, its model, and the type of engine it possesses. Once this is done, you simply follow your particular scanner’s instructions in order to attain readings for your desired metrics.
Benefits of owning an OBD2 car scanner
While tons of car owners certainly get by without owning an OBD2 car scanner, there are many great benefits that come with owning one. Probably the most important benefit is that car owner’s can find the source of “check engine” lights without having to take their car’s into a mechanic.
An OBD2 car scanner is also a great tool to have on hand for routine maintenance purposes. Being able to catch problems early in their existence will limit the amount of damage they’re able to do over time. While there is more than one way to get readings of your car’s OBD2, an OBD2 car scanner is the most user-friendly way you’re going to find.
You don’t want to have to take your car to an auto shop every time a “check engine” light pops up on your dash. Not only could it be a waste of time, it could also be a waste of time. By purchasing an OBD2 car scanner, you can perform your own checkups on your car. This gives you the liberty to decide whether or not you want to spend money on repairs. There’s no reason to leave yourself at the mercy and word of auto mechanics. Invest in an OBD2 scanner. Educate yourself on your vehicle’s well-being. Make informed decisions. Not only will you save time and money. You’ll learn a thing or two as well.
