Snap-On OBD Diagnostic Scanner MT2500 Cartridges Manual Books Case Keys Cords This unit works but you have to hold down the red on button to get it to do anything. I am not sure if that’s normal or if there is something wrong with it. Comes with lots of extras as pictured! What is pictured is the lot you will be receiving. This is being sold as is. Please look over the pictures to determine condition. If you have any questions about the listing please feel free to ask and I will respond as quickly as possible. Buyer pays shipping unless otherwise stated and I do combined shipping however you will have to wait until the other item is done and I have sent you the invoice.. Payments are due within 5 days of winning the auction. Thanks for looking and happy bidding!!
