trying to connect my solus pro to my olds cutlas cruiser and states it is not getting a communication from the pcm...also the check engine light does NOT come on when the key is on. i wanted to see if there are any issues going on, i figure i will try to trace all the wires if all else fails but i was just looking to see if there is a common issue...i know it does have the light driver but dont think that would cause a problem?
