I went to the track yesterday and on my first pass I heated up the E.T. streets launched the car and when I went to slow down the ABS inop light and the low trac light came on. I went around to get my slip and I had ran a best ever 1.79 60 ft. and a 4.96 330 ft. (total time updated in sig) but now the ABS light stays on and the low trac light comes on when I hit the brake, the mph also fell off on every run after that, any ideas??? What have I broke or tore up? THANKS

 

Can't guess, scan it and get the code. Then you'll know for sure

 

I'll betcha a nickel he's not throwing any codes when he scans it.

 

Are the gears a new mod or have they been in there for awhile?

 

Is the conditon still present all the time, intermittent or gone?

There is a TCS shutdown mode where an overtemperature condition such as braking at high speeds at the track will disable the TCS system but PCM will still monitor and light the TCS light on dash.

 

When I installed gears I had the same problem.

 

Bleed your brakes. mine did the exact same thing so I bled the brakes and the lights went away.

 

one time i was almost in a rear-end accident.. just wasnt paying attention then had to get on the breaks.. the abs kicked in and for a while the abs inop light was on but the next day it was magically gone

 

i've had mine go on from time to time. seems like i've related it to problems with a low battery (strange i know...could be just coincidence). but i know i pulled the fuse and it went away.

have you checked the connections on the abs and traction control sensor (whatever that sensor is called)?
