I have a 92 prelude, I've recently changed the front discs & pads. Since then, the 4ws light comes on after about 2 minutes of driving. It then stays on. I have tried to reset the ECU & the light does go out, but then comes on again after about 2 minutes again. I don't know whether its just a coincedence from doing the brakes, but i'm stumped! Hope someone can help!!!! Jeff
