Lately I have noticed my stopping has gone down hill. VSC light comes on alot now especially after I go over a small bump in road while braking to a light, the car lunges forward a bit and feel's like I am on black ice or something. VSC light comes on, this happens everyday now. I am pretty sure it's the Goodyears, they only have 15000 miles on them give or take. I am running 44/42 pressures. should i replace them, or just lower TP on the rubbers
that light means to take it to a dealer or STOP DRIVING IMMEDIATELY if the brake light is coming on also and take it to the dealer. are you mistaken and posting info about which light? if it was the tires causing a skid or some stuff like that it would not be the VSC light that lights up, it would be the little skid icon i double checked. that light does indicate a serious problem with your vehicle stability control system. the tires are innocent. if the system was working properly the slip indicator light would come on temporarily
What he is describing is completely normal when stopping on uneven/broken pavement. Regen braking stops when you hit a bump while braking and the surge is really not so much of a surge as it is a reduction of your rate of slowing down.
Please confirm which light is turning on. I've never had the VSC light turn on while braking, with either my Prius or my FJ Cruiser. Judging by the overall negative comments regarding the Goodyear "lack of" Integrity tires, you're probably reached the limit of their safe wet traction. Tire Rack has an excellent report on how dangerous all tires get with wet braking, once half the total tread depth is worn away. The video is kind of scary when you imagine it happening to you What Honest Abe Doesn't Tell You About Minimum Tread Depths With the delay in switching from regenerative to "real" braking, it does feel like a "lunge" to the car. The car isn't accelerating, it has just momentarily stopped decelerating Note, if the VSC is engaged, the lamp will be flashing and you will hear a warning beeping. This is true of the Prius and the FJ Cruiser
i am pretty sure that the VSC is never supposed to come on, period. unless when you first start it of course the light thats supposed to flash is the slip indicator light] the vsc light coming on is not considered normal operation like diamondlarry says. diamond larry should remove his post before someone dies. if its just the slip indicator light, follow diamondlarry and everyone' elses advice (and apologies to diamondlarry)
yes. but this isn't some back road here.. I am talking about small hairline fractures in the pavement. The VSC light has been coming on alot lately when just pressing the brake pedal and coming to a stop on nothing but near pristine pavement with slight bumps( from the stop light runs that detect cars/tarry looking bumps near intersections) I am thinking the wear with the Integrity's coupled with the the high psi is causing loss of traction most likely. I was merely posting this to see if anyone else has experienced this outside of more severe conditions such as snow or sleet. The other day I was stopping gently and slipped with apparently flat, smooth pavement...it must be the tires..I doubt anything is wrong with the hybrid system.
Sorry, I was in a rush and that was poorly worded on my part. The slip indicator light will turn on. If you go around an icy corner, and the VSC engages, a beeper will also turn on to warn you With my FJ Cruiser, when you shift from 2H into 4H, the VSC is designed to turn off. To warn you, on the dash not only does the four wheel drive indicator turn on, so does a "VSC OFF" warning For that reason alone, I *never* drive on roads in 4H
It's not VSC. Just toss VSC out of this conversation, because all it is doing is causing confusion. VSC has nothing to do with braking in the sense that the OP describes. I'm sure the OP is referring to the slip indicator, which is the same little squiggly line icon that lights up when traction control kicks in. Having that kick on when braking over bumps or cracks is an indication that the tires are breaking loose. This can happen with good tires, but it will happen a lot more with old or worn tires. The Goodyear "lack of" Integrity tires are pretty bad right from the start, but get really bad with time. Get good tires and your traction issues will be minimized. Tom
he has yet to chime in and say it was the slip indicator light, tho. if he posts VSC in the topic and says VSC 3 times in two posts, then i am assuming its the vsc light, heh if he comes back, and says his vsc light did not come on afterall, i'll drop vsc out of this conversation!!! if i had to buy new tires every 15,000 miles i would get rid of this car. for future reference if the vsc light comes on during driving, the following systems need to be checked and or replaced: 1. Check the DTC again and make sure that the normal code is output. 2. IG power source circuit and ground circuit 3. Check the hydraulic circuit for leakage. 4. Front speed sensor circuit 5. Rear speed sensor circuit 6. Yaw rate / Deceleration sensor circuit 7. Steering sensor circuit 8. If the symptoms still occur even after the above suspected areas are inspected and proved to be normal, replace the skid control ECU. most importantly, if the vsc light AND the brake light come on, you are to stop driving and have the car towed.
I'm not assuming it's the VSC light. We have had this same thread discussion at least five times before, and every time it has been the slip indicator, not VSC. Most owners are completely confused about traction control vs VSC. While it is possible that the OP really is talking about VSC, I'm giving this one a 99% chance that the OP is simply confusing his terminology. Tom
does a genuine vsc failure also turn on the check engine light? or is it just recorded as freeze frame data
Okay, if it says VSC then it is the VSC. That shouldn't light up without out a problem. Time to see the dealer or pull the code. Eventually I had to run into the 1% person that wasn't confused. Tom
