2001 & 2002 4R owners: disabling VSC?

Darren · 11-18-2003, 10:10 AM

Well, nothing has been mentioned for quite awhile on any of the forums about permanently disabling this little

, known as VSC. I'm quite amazed, seeing as how there are so many engine gurus and techies amongst us, though admittedly, there aren't that many of us '01 and '02 owners (relatively) to begin with, so our chances are further reduced. Perhaps the 2003+ 'Runners are the same in this regard, that maybe some of those owners could potentially chime in.

I've never looked into it and always had hoped someone would figure out what would need to be done, so I'm giving this one last gasp. I'm sick of this stupid, stupid thing. Does anyone have any ideas what to look for (wire, fuse, etc.)? Now there is a VSC labeled fuse, but I'm not sure if it's related. Once I find the culprit area, may I borrow a gun from someone?

If no one has any ideas, should I check with a dealership? There have been a couple previous posts and I've had a few email inquiries in addition, so I know I'm definitely not alone. Any thoughts you may have would be appreciated. Perhaps a reward is in order?

:pat: so what is a VSC? Is that KFC's older sister?

VSC IS the Devil, also known as Vehicle Skid Control.

I busted my hump over this little bugger last winter to no avail. I tried pulling fuses, relays, disconnecting various leads coming of the VSC relay, grounding the 'TRC OFF' pin (similar to Tacos) on the ECU connects, reviewed wire schmatics, etc, etc, etc. Nothing killed the d@$n VSC. No matter what I tried, it seemed to ALWAYS have a redundant/fail safe path because its part of the ABS braking system. Still pisses me off...

The only thing I can think of is to somehow disabling the wheel spin sensors, but I'm not sure how that would effect the overall ABS system since they're essentially one in the same.

You've tried the most options I've ever heard thrown about. You have also captured our frustration with this worthless system quite well!

Thanks for the input. This is good to know, and kind of bad at the same time.

I'm not in the know on the wheel spin sensors and what all of their funtionalities might be, but I would have to assume that would interfere with the TRAC system if disabled somehow, which those of us who are not locked yet would certainly want to avoid.
