whats an vsa light it came on my car todai idk wat it means or anything
how can i turn it off also when i press the button for the tcs nothing shows on the cluster is it suppose to show something thanks

VSA = Vehicle Stability Assist

just means you turned it off, or the system detected slippage in one the wheels and it activated.
uh if im not mistaken, TCS and VSA are the same thing

well hnic
i press the tcs button but nothing happens i also took out the fuse for the tcs but the vsa light still on
i guess i have to go to autozone check it out

u know from 1999 and up but i am not sure till when the Rl had a suspension problem on mine all the lights comes on VSA ,check engine ,TCS, airbags,ABS ,i mean all the lights
they replace the ABS modulator and accumulator,replace tCS system ,replace Alternator the VSA system almost everything was replace the light went away and came back 2weeks later,and now it was coming loke every 2 days i just sold her and that was it.The car was in the shop for a year

damnn
i hope i dont have to do that
vsa is usuall balance between your wheels i think like one of the wheels need traction idk i ma go tomorrow and get it check it

there was some hearsay about the rear ABS wheel sensors going bad intermittently on RLs and those sensors tie in with just about ever traction system on the car. have all the ABS sensors checked out.

TCS is power modulation and VSA is brake modulation TCS works to reduce engine power when it's slippery, VSA works the brakes to adjust the cars pitch angle and slip in slippery conditions.

VSA works by applying the inside rear in understeer conditions and outside front in oversteer conditions.

my tsc light went off a few times when I had my RL.

I didn't notice a damn thing, it still drove like a big boat.

so you saying that the abs sensors causing my vsa light to go off

as for the tcs i tryied it when it was rainning to see and it does work first u hear a tire burn and u try to do it again and it doesnt do it got better traction but it was movin slow as hell

almost certain. the VSA uses the traction control system and brake system to do its work. there's some Accelerometers and yaw sensors in the equation too, but the most important parts of the system that have a service life are the ABS Sensors. cleaning them might even do the trick. it's likely one of them is faulty.

The reason is if you go into a skid the VSA sends that brake force to certain wheels, but it doesn't modulate it, it send it there and the ABS has to keep the wheel from locking up.

If you've got at least one good rear ABS sensor the TCS will work, but not optimally...ideally it shouldn't have let the tire spin more than a half second before it cut power. it shouldn't spin for more than a SPLIT second, and definitely shouldn't react only after you've let off the throttle once before. Not even the G2's traction control system is that lazy.

well i tried it againt todai for my tcs and u were right i pressed on the gas and the wheels spin for like not even 1 sec and it stopped but it felt like it was losing power but no light came on tho

Mr.KA9

i kno this is an old post but i just recently started having the same problem... i just put my stock rims back on and i just got some new used tires put on the rear for the winter.. the tires in the rear are slightly smaller theyre 215 as oppose to the stock 225 the car is supposed to use, do u think this could cause the problem as well ??
