You are trying too hard. It is not really a matter of how much pressure or up/down. Its a matter of time and change. You only need to bleed off about 5-10 lbs or so, but it takes time for the system to take all the readings and sort things out. Here is what I do:
Initiate the sequence on the DIC. You will hear two honks letting you know to begin at the driver front wheel.
Go to the driver front wheel and bleed it off for about 15 seconds, then be patient. From the time you start bleeding it takes about 40 seconds before you hear the honk to say move on. You can bleed it down the whole time, but you do not have to.
Then you move clockwise around the car. Again, be patient, as it takes some time for the car to acknowledge the step you are at.
When you complete the process for the driver rear wheel it will honk once to acknowledge that wheel, then twice to tell you the process is complete. At that point you are good to go.
However, mine is an'11. And for soem reason the 11s seem to be more agreeable.
