Nowadays, OBD systems can tell you about everything from crankshaft and camshaft position to manifold pressure to ignition misfires.Ĭomputerized OBD systems started coming online with Volkswagen's fuel injected models as early as 1969. In its earliest days, OBD took the form of cooling system gauges, tachometers, oil pressure gauges, and fuel level indicators to give us basic information about a car's condition. On-board diagnostics (OBD) is a system that relies on sensors and computers in your car to display vital information about how your car is operating.
The Lemur Vehicle Monitors BlueDriver, BAFX Products 3127, and ScanTool 427201 are also ideal for the average car owner, since you can leave them plugged into your vehicle at all times and can check sensor status on your phone whenever you need to. The Ancel AD310 Classic, Autel AL519, and ScanTool 425801 are more budget-friendly models that will be capable enough for most users. They also may not want to pay extra money for something that can take snapshot of the information for later recall. Home DIYers who want to be able to diagnosis and fix their own vehicles may not need a model that works with every car make. Your best options will be the Autel MaxiCom MK808TS, Innova 3150f, Launch CRP123, and Foxwell NT301.

If you are a professional mechanic, you will most likely be best served with one of the feature-packed models, so you never run across an error code you can't fix. If you ever had a check engine light turn or, or almost any other dashboard light for that matter, you can use on these tools to determine what you need to fix, and then reset the fault light afterwards. OBD2 scanners take all the guesswork out of diagnosing most vehicle problems. Of these, the Innova 3150f, Launch CRP123, and Autel AL519 offer the most functionality and compatibility with the widest range of vehicles. While options like the Innova 3150f, Ancel AD310 Classic, Launch CRP123, Autel AL519, and Foxwell NT301 are going to keep you tethered to the vehicle the entire time you want to view live data, they are all built tough enough to stand up to the inevitable rough handling they will be subjected to in a mechanic's shop. While these can be very convenient for DIYers who work on their own vehicles, they may not make sense for mechanics since they rely on a phone or tablet to display their results, and most people would prefer not to have to constantly pull out these expensive devices in situations that are prone to putting them at risk of getting damaged, such as in a busy shop. Other models on our list that offer wireless convenience are the BlueDriver LSB2, ScanTool 427201, and BAFX Products 3127. Plus, it works with 57 car models, can display results in 13 languages, and offers wireless convenience. In addition to the traditional systems you expect from all OBD2 scanners, it also checks the brakes, safety, and tire pressure systems, as well as others. The most full-featured, self-contained model on our list is the Autel MaxiCom MK808TS, which has a large, tablet-like screen where it displays all of its data. In addition to providing you with the exact cause of a problem, they can also be used to reset codes, so you don't have to keep staring at a check engine light after the repair has been completed. OBD2 scanners might just be one of the most helpful tools for diagnosing issues in modern vehicles.
