2012 CTS-V 6l90 TCC pressure dump after apply?

well I think Robert hit the nail on the head with the ground comment. for some time now I've had a random Stabil Trak , abs, airbag light that would come and go during 1 key cycle. that paired with the noise on the APP PID made it make sense....i changed intakes about 1.5 years ago and this one came with a shroud that would be installed on the frame rail, to install it you need to remove a ground and use that bolt hole as a mounting point. I removed the paint front both sided of the bracket and applied dielectric grease and reinstalled the bolt through the ground then the bracket and moved on...... this is ultimately the root cause of all my issues. i removed the bracket reinstalled the ground to the frame rail with a stud , then the bracket and went for a test drive ! FIXED

In hind sight i wish i would have logged it with brake position and both APP voltage's but a light bulb went off when you mentioned ground and i went right to it before even test driving again.

Well that's good news for sure, I'll look at the log tomorrow. Just FYI, dielectric grease is NOT a conductor of electricity, it is an insulator. It is a great thing to add to rubber insulator for connectors and such, but never add that to a ground contact point, it will give you a bad ground path.

Well ?. It is insulating the bare frame rails I sanded down ! And I did voltage drop the ground as well.
