One of the main reasons I liked the Trinity is that it advertised being an OBD II reader for general purposes. Well today I tried to read a check engine light on my girlfriends car 2010 hyundai elantra and no luck. Is the trinity setup for all obd II cars, or only certain cars?
Update: My Mom's 1996 Taurus also came up with a check engine light. The trinity can't read the codes for her car either. What's up with that?
