BlueDriver Bluetooth OBDII Scan Tool

Fixing and maintaining your own car (or trying to) first requires understanding its cryptic computerized messages. Lemur’s BlueDriver Bluetooth OBDII Scan Tool packs professional diagnostic capabilities into a tiny dongle that plugs to your car’s OBDII port, simplifying the ordeal and feeding the data straight to your smartphone via Bluetooth. It works on all cars built since 1996, reads and clears check engine light codes on all vehicles as well as enhanced codes on several big brands (with more coming in updates), analyzes diagnostic trouble codes to offer vehicle-specific repair reports, and provides a ton of other data that’s simultaneously fascinating and completely over our heads.
