Anyone know how to make a USB to OBDII cable? I've seen them for sale $140+, but I know I've seen plans to make them, too. My wife's 94 Intrepid has been doing the "Check Engine" routine after long drives, and she wants to take the car to maine next weekend. I'm thinking to avoid a war, I should get it fixed... Is there a way to watch the mil flash codes like on the obd I systems? My Jeep mechanic friend showed me a trick where you cycle the key 5 times and the light starts flashing, but I can't read any of the codes from it /forums/images/graemlins/doah.gif.
