The code says its related to a circuit in the mst cylinder. Other than the message, the car shows no signs I can put my finger on, but not sure what this would do if I road race this weekend and have the system off anyway?

Ideas?

C5? What's the code? You may not have ABS so also no dynamic proportioning.

What code? Can't advise anything without a code and year. Do you get any other messages besides Service Active Handling?

C1296H. It's the only code on the TCS moniker. (others on hvac & maf). It's on an 04 Z16. When looking it up it says it's a mst cylinder circuit issue????

Relax. You shouldn't have any issues since you normally turn AH off. ABS will still function. You need to get a factory service manual. The typical on line reference will mislead you. The failure involves the brake pressure sensor which is mounted on the brake pressure modulator valve. That sensor is no longer serviced separately so you would need to buy a new BPMV $$$ if it is bad. Another potential fault would be in the EBCM (more $$$$$). Do some of the wiring checks in the attached procedure and see if you can find a wiring issue instead. If you can come up with a work around for not having a Tech 2. Could save you a lot of money.

Thx Bill. I'll have to get with a bud that has a tech tool and go through this.

Bill, or others...I also posted in the C5 tech section regarding codes that have been set. I have a couple from the hack that I'm not sure what they mean or how to solve. Any ideas on those?

I think the one concerning the maf may be due to the speed density tune?
