How do you read binary (vag-com) codes?
« on: November 17, 2017, 07:09:30 am »
Looking at a friend's 1995 audi cabriolet, electric roof not working. Have been going around in circles on this but circles are getting smaller. Done boot lid wiring harnesses etc. Using a Hanatech scanner. In the start opening stages the group 1 block codes are correct but the block 2 binary codes are 10101100. They should be 10100101. Does anyone know what the 8 channels relate to?  Now I have---- turn ignition on, handbrake on, turn roof tee bar handle, dash light comes on, push roof up, pull up roof switch and.......... nothing only a flashing light on the dash.
