Well here is the story on my abs light that keeps turning on when i launch my truck sometimes and it really bothering me. Would really like some answers on why it keeps coming on. I just installed a Procharger on my truck and i have a thunder racing custom cam kit with double springs and hardended pushrods and arp head studs, upgraded head gaskets and a yank 3000 stall. Just installed some tr6 spark plugs and taylor 10.4 spark plug wires. Still havent tuned the truck for the procharger but even before i had the procharger the abs light would flash and stay on for a while. Its really getting annoying and would like to see what you all thought of the problem. If anyone can let me know whats up just post and i will see.

 

how many miles on your truck?

maybe a wheelspeed sensor going bad? most abs problems i've seen have been sensor related...

 

yeah that or "brake dust" on the sensor...

 

my truck has 27xxx miles on it
yeah but im gonna have to find which one it is so i can fix it but it never did this back in the day when it was stock

 

melted a wire on the harness by the frame/exhaust/brake booster?

over time the sensor will get brake dust on it no matter the mileage. you didnt change gears did you?

 

No i didnt change my gears
But i will look under the truck so i can see if i have a melted wire somewhere

 

Have you figured out this problem? I just installed a 3k stall and when I launch it hard, it'll spin the tires for a second and then the ABS light will stay on for a while. Doesn't seem to affect anything, although I haven't tried to slam on the brakes to see if ABS works.

Crazy.

 

Same here.. Just installed a circle d 3200 stall
And when I floor it... The abs light comes on too.. Hopefully a tune can take that away..

 

I used to have this problem, said service abs and stabilitrack system. When I swapped converters it hasnt came on since. Definatly a loose connection or sensor somewhere

 

Mine does it now after a hard launch with or without slicks??
