It can read/clear codes, complete vehicle specific tests, connect to all control module systems and is fairly priced in the $150 range. To gain all mentioned functionality, user must purchase vehicle specific software packages.
– The black/clear unit is a bluetooth scanner and connects directly to your iOS or Android device. Apps are then purchased to allow functionality similar to the black unit.
