the Fiance's 02 MC has the DSC, ABS and BRAKE lights on full time. I thought it may have been a fuse or relay of sorts but they all checked out for the 2 systems. I'm not sure if it's a wheel speed sensor because the flat tire indicator is not illuminated as it appears to be with most of the other posts I've read. ABS module? DSC controller (if this even exists)? Any ideas? We'd rather not take it in for service if it's something I can do myself as she's out of warranty.

Thanks!
