The Launch CRP129E Scan Tool is rated 4.4 out of 5 stars on Amazon, based on more than 1,900 reviews. We also found that the Launch takes a bit longer to start than some scanners, but the startup time is still relatively quick (just a couple of seconds longer than the other scanners we tested). However, this connection doesn’t need to be persistent, it is only necessary to set up the device. While the Launch includes many useful features and can perform various diagnostic tasks, it does require a WiFi connection. Some OBD2 scanners have shorter cables that make it difficult to hold the device in your lap once connected. The Launch has an easy-to-use touchscreen interface and a long connection cable. Included with the Launch CRP129E Scan Tool are: Includes oil reset, steering angle calibration, and throttle position reset.

The Launch CRP129E comes with data code protocols from nearly 60 carmakers and over 1,000 models, so this scanner likely knows something about your vehicle.
One plus is that Launch offers free lifetime updates as long as you buy from an authorized dealer. You can also graph live data, reset diagnostic trouble codes (DTC), and perform emissions tests. This 5.0-inch touchscreen comes with an internal battery, so you don’t have to keep the car running to use it. The Launch CRP129E Scan Tool is our choice for the overall best OBD2 scanner thanks to its abilities as a diagnostic tool and extensive features for the price. So one problem on a Ford could read differently on a Toyota or Honda. Although many universal code definitions exist, some vary by manufacturer. You can view sensor data in real-time on modern scanners or translate it into a car code that refers to a specific problem. It draws data from the onboard computer and produces an error code that corresponds with a particular issue. OBD2 devices, also known as OBDII scanners work by plugging into a connector typically found on the driver’s side of the vehicle’s cabin under the steering wheel column. OBD2, or OBDII, scanner ports became standard on all domestic vehicles in 1996 after the federal government pushed to reduce vehicle emissions.
With some exceptions (mentioned in the review), all the components worked well during the testing process. Our testers started each device, connected it to the vehicle, and attempted to run diagnostics using all the features according to the owner’s manual. We tested each of the OBD2 scanners on a 2017 Ford Fusion Hybrid. In the end, we chose the best OBD2 scanners based on the following criteria: Our review team then tested each product in person. To determine the best OBD2 scanners, our review team researched customer reviews from Amazon, AutoZone, Advance Auto Parts, and Walmart.
