If your car's Check Engine Light is on, you need this device.
The MaxiScan MS309 code reader supports all OBD2 protocols, including the newly released Controller Area Network (CAN) protocol. Though it is small, it is able to retrieve same information as large expensive scanners! This OBD-II Code Reader is a handy device for car-owners, DIY customers and even professional technicians to read OBD II diagnostic trouble codes (DTCs) from the on-board computers (ECUs) of 1996 and newer vehicles. With this smart reader, you are able to immediately self-troubleshoot the cause of the "Check Engine" light wherever you are. The Code Reader will also enable the user to erase the trouble codes and shut off (reset) the check-engine light as soon as the vehicle is repaired.
If you have got a connector in your car that looks like this:
