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

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.

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.

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 ??
