To those with ABS... and lockers...

How does that work for ya?

I keep tossing in my mind that even if I got lockers for the front and rear, my ABS will interfere.

VSC is related to the ABS some how... but Im thinking with my center diff locked... it said "vsc disabled" or something but my abs still determines if im skidding or not...

It would be nice to be locked front and rear, but if its not going to make a difference, why spend all the money on the lockers?

I guess im just all shades of confused on this subject... never had to deal with ABS and VSC before...

ABS simply pumps the pedal for you when you begin to slip or lock up the wheels during breaking. The locker should not affect this at all. What you may be confusing this with is traction control which does attempt to stop any wheels from individually spinning by applying pressure to the brake at the spinning wheel and therefore slowing it down. The input from the wheel speed sensors tell the vehicle which wheels have traction and which do not. I don't think traction control can work with the diffs locked which is why it would be disableing itself when in that mode. Like I said tho, the ABS affects all breaking wheels so it is not affected but the diffs being locked.

I thought we've covered this already!

Lockers eliminate wheel spin, thus the traction control system has no reason to engage if locked. I know of about 3 folks with 2001's and 2002's who have dual ARB's, "Fear" being the most active on either of the boards. My turn is nearing. Definitely not a waste of money.

Feel free to PM me about any related questions on our system.

we did cover it... i just need to be slapped every once in a while...

hehe... I'm just checking... (getting coffee)

Lockers eliminate wheel spin? My experence is lockers make all wheels spin together at the same rate, but they can still spin. I don't know about those fancy traction control systems though.

Lockers eliminate wheels from spinning at different speeds from each other therefore the trac control will not come into play.

On a related note. Why does abs shut down when locking in an electric locker?

Darren

Does it shut down completely when the locker is engaged?

I know the ABS sensitivity is considerably reduced in low range. My ABS generally enages at 15 MPH or greater (on snow), but I can lock the wheels at any lower speed than that. I mention this as it might be related to low range as opposed to the locker being engaged.

Darren,

At least on mine, its completely disengaged. I verified this yesterday when driving around in the crap weather we've had in the northwest, no ABS whatsoever with the electric locker engaged. This is not likely the case for lockers other than the stock e-locker.

Yes, ABS turns off when the e-locker is engaged. Thats why the ABS light comes on. I dont have any other silly traction control devices though.

That is strange.......I would have thought only traction control would be disabled, but ABS too?
Just doesn't make sense.....must be a reason.

Just theorizing here, guys. But if you have a locker on, both rear wheels rotate at the same speed, regardless of whether you are supplying power or braking. If I understand ABS correctly, it monitors each wheel for independent variances in speed compared to all the other wheels. Therefore, ABS would probably be useless with the locker engaged since it would monitor one wheel compared to all the others for differences in speed and 2 wheels will always be rotating at the same speed.

It's just a theory, tho...

I didn't think that he ABS was able to regulate each wheel's braking pressure but I guess it must be able to. This would make sense because as already pointed out, the rear wheels would just skid together regardless of brake pressure with a locker engaged.
