Disable VSC, TRAC, and ABS without damaging factory wiring

dereky,

I am not 100% sure as I did not use a stock switch when I did this mod, but I believe once the switch is modded pushed in is on and system is engaged and working, popped out and the switch disconnects internally turning it off thus causing an interrupt in the system and thus enabling the mod. Once the mod is activated the only way to reset the system is to push the button in and power off and restart as this allows the system self test, find no faults and re-engages the system. The momentary TRAC OFF switch is used to turn TRAC OFF only up to a certain speed, approx. 23 mph I believe, this mod allows the system to stay off at any speed until you decide to turn it back on.

So it sounds as though all is working correctly then?
 
Do you guys use this mod when off road/rock crawling. It just seems like you would want it on if one wheel started to spin the power would transfer to the other side. And when I say on I mean not using the mod.

It's good when ATRAC starts being an *******. Also good in bad conditions, like snow, when you want some wheel spin!
 
So I went to the desert this weekend and experienced atrac for the first time. What a P.O.S. design. It should be illegal to install that without a switch to turn it off. Definitely will be doing this mod before my next trip.
 
Amazing!

New to the forum, but found this thread when searching how to disable ATRAC. This mod is truly amazing. Just did it this morning and took her out for a ride and the truck drives just like it was meant to! I want to thank the inventors for such a great trick!

Welcome to the forum and I'm glad you enjoy the mod. This was the first mod I ever did to my truck haha.
 
Can someone tell me what wire to splice. I thought it was the white black on the two prong but just double checking

I believe what you guys are trying to accomplish is the VSC mod using the stock VSC switch. In order for this to work you need to do the mod then mod the switch, as the stock switch is momentary and you need a switch that will stay on or off. The mod itself is pretty simple and well covered, but here is a link to mod the switch. Hope this helps.

How to convert an OEM momentary switch - Toyota FJ Cruiser Forum

Wiring is such a hard thing for me to wrap my head around. I assume if i was to do what this guy did with this switch mod, it would be taking care of everything?

To be honest now after rereading several threads, I am not sure. The switch Mod was done for the FJ which prior to a certain years it did not come with a switch to turn off VSC so they are modding that switch to be on/off. On our trucks all that is needed is a temporary disruption in the VSC circuit to enable the mod until the truck is re-started so a momentary switch should work. I don't know if this switch is a pulse momentary or momentary the whole time the button is pressed as it takes about 1/2 a second or so for VSC to be disabled and if it is pulse momentary I do not know if that is enough time of disruption to enable the mod. I hope this makes sense.
 
Ummm.....that just read as Charlie Brown's teacher.....lol

I am far from familiar with your 4th gens, BUT, have you tried just holding down your VSC button and seeing if whatever you want to accomplish works?

I took a glance real quick at that FJC write up and all it seems to be doing is just that. Simply put, I think it just holds the switch down for you, lol.

We don't have a vsc button except on 08's or 09's
 
I am not sure what the differences are between the VSC button and the Trac Off button, but this is what i have. With the TRAC OFF button i can hit i and spin the tires, but as soon as you let off even a little it kicks in.

So you have to press and hold the button while spinning tires? If you let go while spinning the tires, does traction kick back in?
