Common cause of the parking brake and ABS light to stay on (when the parking brake is not set, of course 
) is failure of the rear wheel speed sensor. This is located on the top of the rear differential.

RE: check light
thought I would add my problem to this thread. My ABS is showing code 4 "closed HCU RWAL reset switch" I performed the HCU test as described by the Mitchell book and came up with nothing. The HCU connector looks good and the 14 pin ABS connector looks good.
