You can reset the light by going underneath. You will need a 14mm wrench and a good hammer.Take the wire off,then with the wrench back the cap off,say two are three turns,then with your hammer tap the block a couple of times.the rest is just reverse,just don't over tighten the cap,you also need to inspect for leaks. One other thing to do before you do the repair put a piece of tape on the master cyl. cap.
Hopes this helps, it fixed mine.
