i looked in the forums and really couldnt find anything on this matter of the vsa, i found issues with people getting into an accident and the vsa light staying on, but my case is a little different and i was wondering if you guys ran into this issue or know about it.

So i own a 2007 GPW S2000 mods are HKS Hi power with Buddy Club RSD other then that my car is stock.

I was driving on the freeway on the 10 E and theres a section of the freeway where it gets really bumpy and harsh, and in that section my VSA light turned on and cut the power, i couldnt go passed 45mph in 6th gear, i had to turn on the emergency light and pull over to not cause traffic & etc. I turned off my car and turned it back on, the VSA turned off but the Engine Check stayed on. i started to drive again, making sure the car was fine. it was, the next day i turn on the car the engine check is gone and i start driving, i go over another bump, (where the tire slipped alittle) and the VSA light turned on.. and same thing issue occured.

i know usually if the car thinks the tire is slipping it'll cut the power (while the ! flashes) and it'll be back to normal.
But i drove with the VSA off and it turned on like that. I wasnt driving crazy or making any turns. i was just driving 70-75 mph going straight. and going over the slightest bump where the car thinks the tire is slipping the VSA will turn on.. and i had times where it would just turn on...

thanks

 

Could be a loose connection maybe check ECU, fuse box etc.
