Line lock and ABS

[OhhFiveGt]

I installed an SLP line lock kit in my 05 and it hasn't worked at all. The brakes are all properly bled and the switch is working because it does hold and release the solenoid. It does hold the brakes and keep the car in place but only at a stand still.

As soon as I even let out the clutch not even give it any gas it pushes right through. There is an ABS light on in the car and this is the only thing I can begin to think would cause the issue. Would an ABS light effect it considering it goes to the ABS pump and not the caliper itself?

Also when I scan the car I get and unknown ABS code and don't even know where to look for the issue. Any help would be great I've been looking all over and can't seem to find anyone with this same issue.

do you turn off your traction control before using line lock?

This is very important. when you turn your TCS off ABS is disabled. So no chance of confusing ABS

if your TCS is left on when you use the line lock it will try to find traction for you buy cutting the throttle and retarding ignition.

the button is on top of your radio, to the right of the power outlet. Some people press this button every time they get in the car LOL.

And to be honest, even in snow and wet, TCS has never helped me. I am used to working a RWD V8 car, and it does nothing for handling really.


also, assuming that you are turning your TCS off, look at which way your noid is facing. if it is facing the wrong way it won't work right. I forget which way is correct, I'll pop my hood and look if that is the problem.

and I don't mean to insult your intelligence about the TCS, its a mistake a few people make.

It should look like this

The ABS being on TCS is always off, I also turn my TCS off every time I get in the car no matter what anyway. I will look under the hood tomorrow and make sure it is facing the right direction.

Should I worry about getting rid of the ABS light if everything else is correct?

just turn off traction control (and in the newer mustangs Advance Track), engage the linelock and do your burnout as usual.

you will likely get the ABS warning lights and traction control fault code, etc.. but they will automatically go away the moment you drive a few yards on all 4 wheels.

this is pretty much the same as running the car on a dyno where the front wheels are stationary and the rears are spinning.. we go through this on a daily basis

"when you turn your TCS off ABS is disabled"

Did not know that ABS is tied to TCS. Can someone else confirm?

Interesting.

 

[michael.konor]

Did you install your line lock "pre" or "post" the ABS block?

Most certainly not.. ABS will continue to function unless you physically disconnect de-power the HCU (by the intake filter).. or you can disconnect a wheel speed sensor

I worded that wrong. What I was meaning to say was with the ABS "light" on not the ABS system TCS is always off.

I think you guys are also thinking of it wrong the light does not come on when I engage the line lock or try to burnout. It's constant as soon as I start the car it's there and does not turn off.

hmmm, I was told by a pretty reputable source that the ABS turns off with the TCS.

I will try turning off my TCS and slamming on the brakes and get back.

Pump the brakes before engaging the linelock to make sure you get a good hold. If it still rolls through, you may consider dual solenoids after the ABS block. I run duals myself. Back when I installed mine, there weren't a lot of people running line locks on the S197 and I wanted to make sure there were no ABS issues. Now it seems a lot of people are running single solenoids before the block with no issues, but my setup might be one to consider if yours doesn't work out.

 

[michael.konor]

^^^^ I'm running the same dual solenoids after the ABS Block without a single problem since 2008.

I never said turning off the TCS turns off ABS you guys clearly are not understanding what I'm saying at all.

The car has had an ABS light on for months before I even installed the line lock so whatever is causing the light is not related to the line lock at all.

What I was saying is because all these comments saying turn off TCS is that due to the ABS light being on the TCS is automatically off. Whatever the issue may be it is not user error the TCS is off the line lock is installed correctly and the switch is working. That is why I was asking if the issue with the ABS which happened BEFORE the line lock was installed could be causing it to not function properly. If you can't help that's fine but keep the dumb comments to yourself.

I would just clear the code

as far as the line lock not holding well enough, vein type noids (the one SLP uses) need to be installed in the correct direction or else you will be able to push the car through the line lock. I will take a pic of mine later and post it.

 

[NUTCASE]

I know this because the first time I put my noid in I put it in backwards and I had enough pressure to hold the car in place, but the car would push when I let the clutch out. called SLP, reversed the noid, 3 years later still going strong.

 

[NUTCASE]

do you see how the brass part of the noid is to the front of the car and the silver part is to the rear? If it does not look like that flip it around.

IMO, clear your code. drive and see if it comes back. If it does diagnose ABS seperatly.

if you do this and still have problems then I dunno

 

[OhhFiveGt]

I'm going to have a look at the car tomorrow wasn't able to get to it today I'm about 90% sure that is how I have it. I put it in and then haven't really driven the car since so I could be wrong. I'll try to clear the code as well but do you have any idea what could cause an unknown ABS code to come up?

never heard of the ABS unit going bad but its a possibility.

usually the problem is the wheel sensors. if the wheel sensors are not bad look for a shorted wire and save the ABS unit for last.

Are you setting the line lock with the pedal down and then pressing down a couple times after setting it? If you're doing that and it won't drag the fronts, sonething is wrong.
Either way, get that ABS light sorted out
