Brakes lights come on after tire size is put in

VENSION · Post by **VENSION** » Tue May 17, 2011 5:40 pm

The part # u7194
Revision is v.9r22
The vechicle is a 2007 chevy silverodo pick up
The tire size is 265/70R17
The problem that I am having is that after installing the modified tune for the correct tire size 31.5" and the performance tune the trucks warning lights for the brakes and abs system comes on . So far no one at Diablosport can come up with a correct answer to the problem.

Should I just return the programmer and buy someone elses????

Help, Vension

Are you also disabling the speed limiter when you do this?

I have the same issue, I have an 07 vortecmax 6.0L chev. Put on both the 87 and diablo tune. Never set my tire size until I read some forums. Since I'm a mechanic I put on my Solus pro Snap-on scanner and my front speed sensors were at 103 kmh and the rear sensors were at 112kmh. The abs code is a C0245. I then re-installled the tune with the 275/55R20 tire size and went for a drive with the same result. I did have the max speed turned off on the second tune. Upon re-installing the stock tune all my speed sensors were at 107kmh.

I am having the same issue. In a previous thread, Mikel said it was an issue with lifted trucks that there is no fix for.

Lots of people have the same problem with trucks that aren't lifted.

My point exactly. I find it hard to believe that the lifted trucks and non-lifted trucks have seperate issues when they are doing the exact same thing.
