Well ive been hitting up the pawn shops lately just looking for **** to blow my money on, and i came across a LIKE-NEW OBDII scanner for $30 and couldnt pass it up. it allows me to scan and erase codes and has everything it came with new. looks like it was never used really. the pawn shop didnt know what it was lol so i feel i got a steal. bad news im throwing 6 codes but that should be getting fixed soon... btw its a cen-tech brand??? never heard of it but works great!
