My car has a problem and I have no idea what's wrong.

When I'm cornering around speed 55mph+ WITHOUT gas, the VSA starts to flash. Not those sharp turns but those turns that you know will never make you spin in that speed. Same situation if I were stepping on gas then the VSA wouldn't flash. Initially I thought it might be the problem of LSD, so I changed the oem 1.5 way to a 2 way one. But the problem remains.

Anyone has any opinions or recommendations how I may solve the problem or where to check?

No one has the same problem?

How does your tires match up front to back height wise?

I would check a couple of things.

1. tire pressure VSA works off of wheel speed sensors(ABS system) if the pressures are different the size of the tires are slightly smaller.

2. check the ABS sensors rings ect. to make sure they are not broken or the ABS ring isn't cracked.

3. Check alignment.... I know this sounds weird but after an alignment the problem went away.

4. and like rrounds said, tire sizes side to side and front to rear matter. if you got a new tire on one side of the front or rear axles cuz of a nail, blow out, hood rats shoving a knife in your tire, ect. It'll off set the wheel speed sensors. or if you have non-stock sizes. like you kept a 215 in the front but went to a 255 in the rear and kept the aspect ratio the same it'll throw the sensors off.

Clean your ABS sensors, it's easy and quick and removes that variable. It helped my over-active VSA problem. But I am also of the opinion that our VSA system just does not like the 225/255 tire combo. I get way more VSA intervention with 225/255 than I did with 215/245 or 215/255. And as others have mentioned, it is extremely sensitive to any major difference in tire wear between front/back or side/side.

I forgot to say...my car is hardly to go straight. It will be pulled to the right if i don't hold the steering.
I've done 4 times alignment since the symptom came out, I checked all bushes, I even changed new tires, new LSD and new P.S. gear box but this problem was not solved. BTW I been running 225/255 for the past year and nothing special happened...until 3 months ago. There must be something wrong.

Thanks for you guys suggestion, I'll definitely clean the ABS sensors. But I just don't feel that's the main reason from my sixth sense..
I guess I'll check the drive shafts later since it relates to gas release/open and traction. Hope I can find anything abnormal there..cus it seems like the only thing I haven't checked.
