4RunnerGeneral discussion forum for the Toyota 4Runner.
This is a discussion thread titled "VSC/Trac kills the performance", within the 4Runner forum, part of the SUV Forums category.
I realized that the VSC/Traction Control really bites into the trucks performance, it just seems like when the power should be their it shuts down.
I was doing about 35/40 and cut across the road and their is a dip that they did not pave when they did the road cause they don't want cars cutting across infront of other cars guess it is a safty thing, before they paved the roads my friend could cut across the road doing anywhere from 80-120mph in his mustang and it was smooth but now it is so messed up and when I had my pathfinder I could cut across doing any speed up to 40mph and even 60 a few times and I could get the tail to slide a little and it was cool but now doing the same thing with the 4Runner, I hit it tonight and got some air and the truck just shut down I literally felt like I was coasting in neutral for a few seconds.
Also on hard take offs, it feels like it lets the tires spin and then it kicks in, truck kinda acts like it forgets but then steps in.
Some places it is called for others it is not, but I so wish their was a switch to shut it off for spirited driving,
I would like to know if they do anything to the trac and VSC with the SC
I am less than thrilled myself with the traction control. I made a sharp turn on a wet road and stepped on the pedal. I would have expected the front to grab right away, but there was a delay before the power shifted. Mean time I was heading straight for the curb. Luckily the fronts started turning just in time.
I am also not real happy with the down hill braking. I have nearly put myself through the wind shield several times by lightly pressing the brakes when going down hill only to have them grab and launch me forward out of my seat. I guess this is what you get when you buy a car the first year they come out.
I've never really had a problem with the down hill braking, the downshifting is a pain cause I tap the brake to slow down and it starts down shifting and then I hit the gas and Im like whats the point.
Don't know if this has anything to do with a 1st year vehicle but like my last vehicles Im gonna be watching the 4Runner and test drive a new one ever now and then when the model year changes come out and see if it varies much, don't want to see a switch to turn the VSC and Trac off
My friends have had several domestic cars all with Trac you can turn on and off, I remember him telling me his Grand Prix was faster with the Trac off and slower with it on cause with it on it was depowering the engine to not spin the tires.

I guess when I hit the dip and got some slight air the truck did not like that and shut down cause I felt like I was coasting in neutral.
Do I drive it hard, not really 90 maybe 95% of the time I cruise and enjoy the ride cause I just want to have my clean record and watch the insurance go down but I do like to take off hard
They probably detuned VSC after learning the hard way from the Sequoia. When VSC first came out on the Sequoia, it was WAY TOO sensitive and would throttle down the engine while trying to merge in fast moving traffic from a turn....THIS IS BAD.
So I guess they allow for tire spin and allow so many rotations before it engages...it would be interesting to see if you can get a full tire rotation before it kicks in?
Originally posted by kaneman I know what you mean.. I'm not light on the throttle all of the time either.. I've never caught any air though..
Thinking about it, I doubt I was in the air more like the weight went up and the traction was less on the wheels so it kicked it till everything was back in control
Originally posted by kaneman I wish Toyota would've added a switch to disengage as well.
You can disengage the VSC via locking the center diff.

Originally posted by EDGE Hmm. Maybe VSC is programmed to engage if the trucks shocks are extended past a certain point or something?
Nopy, but that would be pretty funny! hehe. From playin alot w/ my 4runner, it seems as if the VSC kicks in if I try to drive hard and turn at the same time. Try this on a gravel surface by going straight and then turn and throttle at the same time. The VSC will kick in by pulsing the brakes/gas pedal. Kinda a pain in the rear but the system works like a charm. It will ensure that your vehicle will not side (fish tail). ofcourse this system will only work so much but it will work very well to it's limitation.
The problem is the TRAC system. This system can not be disengaged (turned off). This is the system that causes you to get hiccups sometimes when you launch... It notices the slip during straight acceleration and then the TRAC system kicks in. I really don't like it but ehe nothing we really can do about it. Although I've read someone trying to disengage the trac system but I'm not sure if he's been successful at it at the moment.

been their done that
I fishtailed once in the rain coming off the highway and I cut the wheel to avoid a broken down rust colored jeep and the back broke loose but at that speed even I was like OHHHH CRAP the VSC kicked in and all was fine kinda felt like braking the end loose in snow
I hate it. Yes, saftey innovations are good (like air bags) but there should be switches to turn them off. Like for off roading and stuff. Im assuming that if its a system on the vehicle, then there must be a fuse somewhere to cut the power.

The car manurfactures are getting smarter, it use to be you could pull a fuse and that was that but now the fuses are integrated into other parts, example friends father had a Saab he leased and was going over his mileage so he pulled the fuse that said "odo" and the counter stopped and all was good, his daughters Nissan you pulled the "odo" fuse and the headlights would eventually turn off, I guess they set it up to stop the altenator and just drain the battery, I eventually found the way around that
I'll find a way, I think I found the plug to stop the odometer
