Hi everyone, I just got a new ELM unit and adapter cable and can read most of the things I wanted to in the car but cannot connect to air con?????
The adapter cable I use is a green one with pins 1,7,9 and 12 connected.
According to my "googling" Air con should be on 9 so has anyone any ideas why I can't read it and I can everything else?
It doesn't even find it when I do a module scan but finds the others.

HELP!
