FJ ABS Kill Switches

[Big Red]

I thought this might be a useful thread.

I was thinking of getting the ABS kill switch in my '12 FJ as when i turn it off from the factory switches and brake in the sand it still somewhat kicks in.

I was looking for some more information about this but didnt find much so i wanted to ask for opinions etc.

Thanks

[TD="width: 100%, align: center"][LEFT]ABS was designed to keep wheels from locking up. ABS was designed to make driving safer.
Locked up wheels are not steerable. For example, you would not be able to steer around an obstacle with locked wheels - with wheels locked you would slide straight into it. "Not steerable" means that even though you are able to turn your steering wheel and the tires are actually turned as well - the vehicle does not follow this command.
Most ABS computers also achieve maximum friction between tire and ground for short stopping distances. *
Not so on a dirt road.
Sand and gravel under your tires act like tiny ball bearings when you step on the brakes. As a result there will be very little friction/traction between tires and ground.
Therefore all four wheels want to lock up immediately.
ABS keeps them from doing so.
So you roll and roll, and roll, and roll. You are possibly rolling too long and your stopping distance is going to be very long. Too long to be safe.
To deal with this known shortcoming of ABS, some manufacturers had installed a kill switch for ABS in their four wheel drive vehicles (for example Mercedes-Benz G-Class) but recent changes in the law prevents them from providing this option any longer. Seasoned four wheelers have either installed their own kill switch on the dash board or simply pull the ABS fuse before hitting long stretches of dirt road.
Here is what they get with ABS off: When you hit the brake good and hard the wheels will lock up (this time locking wheels are good for you) and start sliding - but the tires will immediately begin pushing sand and gravel - this builds a little berm in front of each tire which very effectively slows down the vehicle.
In fact, stopping without ABS on sand or gravel is so rapid that you better have your seatbelt on - otherwise you will end up hitting your nose against the windshield.
*Some ABS systems prevent locking wheels but not really for shorter stopping distances. In fact some create substantially longer braking distances.

have you tried removing the abs fuse?

[Big Red]

Hey DL, I was shown what to remove in the engine bay. I was just wondering if anyone has experienced any problems with it?

I'm just wondering, if anybody, in fragments of dangeruous milliseconds, has a time to search for a switch somewhere placed on a dashboard between other many switches?

I know some people, who are opening they door, to switch the inner light, as they don't know which switch to press to activate such a function. (I assume that they didn't ever read car's manual, right DL?)

[Big Red]

i only want to use it offroad .... it would be silly otherwise

[Duck Commander]

Bro let me come back, I will ask my one genius buddy to do something on your Big Red, he has done it for mine and his car.
but Ours are 2008,2009. for sure there will be something to do on your model.

Lol, yes there are people who are extremely challened when it comes to buttons.. But I don't think we have this issue here.

In fact, you can easily simulate a No fuse with a switch. The wiring would be simple, but since I never did any electric work on my wife's FJ, I would not know exactly how to pass the wires into the cabin.. Moreover, for a newer car, I wouldn't recommend any splicing since that may impact your warranty. Sticking with the fuse removal is the convienent way since you don't off-road daily.
Once the fuse is removed, you will most likely get some waring lightsm but that should be it. Replace the fuse and re-start the car and things should be cleared..

Finally, Bu Salem is your ultimate reference for all things FJ..

DL, a very dangerous theory in respect of your wife's ownership. I know, you could explain to her, all these experiments are just for her good, but I can imagine some dangerous sparks in her left eye, at the moment you would try to explain all this hocus-pocus... :060:
