ABS

[lawnmoman]

I have an 07 Ram Hemi. I have what i consider a major issue. Last week i had to avoid an accident by braking. It seems that even if an ABS light does not come on, it does not mean it is working. I have 3 out of 4 tires (2 weeks old i might add) flat spotted. You see when you load a tune apparently ABS is deactivated without you knowing it. I would like to speak to a representative about this.

ABS is not deactivated when you load a tune. It works fine on my 2006 300C. I have an 02 dakota that is only ABS on the rear brakes and it dose what you discribed when I brake hard on pavment no tune loaded.

Yeah we by no means touch the ABS module.

so the posts i see about abs light and non-function aren't there?

If you have not already, please make sure your Predator is up to date on the 9r03 revision.

Thanks

I don't know should this be some what of a concern? I have an 03 ram hemi and after I loaded the tune my abs light and brake light stayed on until I put my truck into drive and then back into park.

First you have to read the posts carefully. Some people are turning off ESP completely with the Predator selecting what is now called "dyno mode". After that some people are having some problem with their ABS light staying on (various things that I think were due to some combination of selections but I haven't paid attention). You are the first that I know of to say that your ABS did not work AND the light was not on. Have you tried putting it back to stock and recreating the stop you made to see if you get the same effect?

ABS is pretty much separate from ESP/traction control. The tunes reduce torque management which in turn reduces ESP. As far as I know they do not touch ABS.

There have been a few cases of people using the U7137, loading a tune, and the ABS light stays on...I have not seen Diablo specifically address these concerns for some reason

I thought they went to a different version CROM and it resolved it? In any event, that's VERY different from ABS not working and the light NOT being on.

We've certainly dealt with it, and in fact made sure as of 9r03 no such thing will happen.
I did not notice if you said you were on the latest revision yet?

[lawnmoman]

Ill try to answer all.
I have not duplicated nor do i want to on dry pavement. As i said these tires were new. I will have them shaved next week.
i have the 9r02 crom.
I will play around with rain this weekend (fingers crossed).
Try tuned and not to check when where and how.
then will load 9r03.

[Black05Hemi]

Fair enough Mikel...And, yes, i've been on the latest revision, ever since johan released the beta...

I have latest update and still have problem with ABS / Brake light. Diablo needs to get this problem fixed
