Disable VSC, TRAC, and ABS without damaging factory wiring

[info4tim]

I have a question related to this thread. But the Inverse! Specifically since my O2 sensors n this now my cat is bad Toyoyo decided if you want your VSC, etc to work...Must spend the $2000+ to fix the above...or no goodies! My lites have been on my 03 SR5 now for probably 6+ years. Any way to get the VSC etc back online without spending oodles of cash!?
Thanks much.

Yes. The only way is to clear whatever CEL code is causing the fault. If it is related to the CAT, you can try O2 spacers, or electronically trick the readings to clear the code. After that,you may need to do a zero point calibration, then it will work as it should. With out clearing the code you won’t be able t get those lights off and have function of the system.

This is awesome. I plan to do this mod once I find my new to me 4th gen.

What are o2 spacers? Where to get, install? How to do 0 point dist?

I am having an issue where the car occasionally won’t accelerate when pushing the pedal but everything seems like its running fine.. if I restart the car it works normal. This is an 03. Is that a similar problem?

I hate necrobumping especially when I haven’t been on here in years, but I had a question. What are the downsides to just pulling the ABS fuses? My abs goes off literally whenever I touch the brake.

Try it and see what happens. Should basically just disable the ABS pump, but you'll still have normal hydraulic brakes - old school.

Back in the early days, I've heard of people putting in switches to disable ABS on cars for offroad and winter driving purposes - a locked wheel was better for digging in rather than spinning over loose surfaces. Hell, I used to have an old Audi that had a factory ABS defeat switch right in the middle of the dash (along with the locking diffs switch :rockon.

So I took out both fuses and about 2 miles down the road a super loud, high pitched alarm started going off constantly. I pulled over and replaced the 40 amp fuse but left the 120 out and the alarm went away. My 4runner stops on a dime now, I’m so happy to have my brakes back.

Actually, I go further than that. Grew up with my family having several. My first that I actually drove was an 1986 5000CS Quattro Turbo. I grabbed the picture from the web to highlight the example. I miss that car.

I picked up a 4th gen 4runner sport and the previous owner told me he installed a switch that would kill everything for four wheel drive only (I'm just rephrasing a two year old conversation). I now have lights VSC/Check engine lights on all the time. I think I might have hit the switch without actually turning the engine off. Will this cause the lights to stay on? With the switch off I get the parking brake light and switch it on and it goes away, so I think the switch is still working.

Can pick up a OBD reader and go from there.

I've read about gas caps being an issue, but I really think I did this one myself...

Any thoughts?

Thanks!

There is a thread somewhere in this forum that states tapping into the red wire off the master cylinder to add a switch to disable traction control in 4WD.

I can’t find it at the moment unless it’s just further down in this thread.
