dash light on
 

i have a 2007 dodge 6.7 l 3500 6 speed manual trans just got the 5inch exhaust, efi live 5 position switch and kn cold air, egr,cat, dpf,and thr control valve deletion done about 6 months now. i have the abs and brake light that comes on and if i pull over shut it off and restart and go down the road a 1/4 mile it will clear and sometimes come back on. it doesn't matter if i am towing anything or not. looking for what it could be or what is the cause. any answers from you all?

Go to Oreilly's Auto and have them pull the codes for you. At least that'll give you a clue.

I had one that set a code for a bad check valve. I discerned that the fluid had been in the system for some time, had the local shop flush it and clear the codes, and it stayed clear. They thought I was nuts. I said, "I'll sign the check."
