back to the top to start another week...

Well, spoke too soon, took a little longer drive than usual today, and the abs/emergency brake lights are back on now... Hopefully someday we will get some help for this!!!

back to the top ... any ideas yet?

i'm having the same problems..parking break and abs lightsare always on since i installed the predator i haved a U7918 r.9r12 on my 2000 5.3 silverado...idk hopefully somebody can figure this out

back to the top....

another monday of driving without my predator...

Well, tried the changing of tire sizes, still to no avail. Think its pretty bad how we can't get any support, or any attempts to answer. We spent 3-400 on this product and it only throws service lights. Please can we get some support on this Diablosport guys!!!!!

any news? Any update? Anything?

There is a 9R12 update but I dont know if that included any adjustments to the tuning for you.

yeah I'll try the update but Im not that optimistic... figure it'll be a predator free Christmas unless I hang it from the tree or replace the star on top got to get some kind of use out of it

hey guys not tryin to be a smart a** but my buddy has a predator on his 07 silverado and his abs light came on as well but he left it on and drove for a few days and it went off and hasnt come back on.. However his is the CLASSIC!!! not the NBS soo is this problem just stayn on on the nbs trucks or most all 07 08??

NBS I think ... I've left my tune in for about a week in the past I make a 90 mile a day commute and it would throw lights without fail

Check your glove box door, inside, for one of the following codes: "JF3" or "JF7"; if your see either of these codes, you've purchased one of Chevy's rare phenomenons. Concisely, the codes above represent two ABS module manufactures; said modules cannot be re-programmed, period! The modules remain related to an ABS towing option, normally on work trucks. Regardless, if you see JF3 or JF7, you can't resolve the issue with any combination of programmers and or odometer add-ins; trust me, I've tried.

If you want the brake or ABS light out, simply lie to the tuner concerning tire size. I'd recommend rolling out your true tire diameter, with chalk, on pavement; and step your tire sizes down until the light extinguishes, likely near the tire diameter on the driver's door tire label (hint, hint). Finally, JF3 or JF7 are l@@king for near OEM parameters; and anything outside those parameters, you get a wondrously illuminated ABS/Brake light indication! Henceforth referred to as the "ABS Annoyance Light."

Note: this remain especially true concerning gear changes! ouch!

ok well atleast thats an answer... and yes evidently I have a "JF3" so does that mean Im just screwed cause I've tried everything even remotely close to the 265 65 R18 stock tire size with no success?

thaks for the info mypostoffice, how did you find this out that jf3 or jf7 is the issue?

I have js3, my stock tire size that is in my stock backup is 265 65 18 (I actually have 285 60 18 on the truck) I have installed the 87 tune with dod disabled and did not even mess with the anything else and the lights come on(9r05 9r07 9r10) I had no issues with the 8r10 so that leads me to believe that the jf3 or jf7 doesnt matter maybe?

I just installed 9t09f and no lights so far, ive put about 10 miles on so far so we will find out, if not its back to 8r10

tech guys for diablo any fixes? or do we wait because "you are working on it"
