Review: Just read the instructions. Super easy to use. Added a little research on top of the codes I was able to diagnose my friend's engine lights as a leaky gas cap. After we fixed the issue we kept track of the time it took for the codes to "fall off" and once they did the car sold for $3000 more than was offered with the check engine codes lit up. Not bad for $30 bucks. Review: The check engine light was on for my 1999 Honda Civic LX. It had roughly 181K miles. This tool does not require any batteries because it uses your vehicle battery once you turn the key in the ignition. it then scans your car for a few minutes. It will give you codes for any problems. These codes can be looked up online to locate where the problems are. In my case, the tool completed the scan and showed that there were not any problems. I scanned again with the same result. After disconnecting the tool and turning on the ignition, the check engine light was off. It reset the engine light somehow. There are more expensive tools of better quality, but this works fine for basic scans on older vehicles. ## Features - Autel MaxiScan MS300 Car OBD2 Scanner Code Reader Engine Fault Code Reader Scanner CAN Diagnostic Scan Tool for All OBD II Protocol Cars Since 1996, Red - 👍【TURN OFF CHECK ENGINE LIGHT】Autel MS300 OBD2 scanner is an easy-to-use plug-and-play check engine code reader that read and clear codes.
