Protege Sunroof issue/ABS light
 

I just picked up a 2000 Protege ES at an auction and I seem to have an issue with the power sunroof. When it closes it seems to go too far exposing the rear edge to the elements. I am able to back it out to normal height...but I was wondering if someone has any tips on adjustment or a link to where I can get info on fixing this? The headliner has water stains from this problem as well.

The second issue is a persistant ABS light on the dash. Is this just a reset or cause for concern?

Thanks in advance!!
