Engine/Transmission (1998.5 - 2002) Brake and abs dash lights on with tach malfunction.

I just had my red brake with my yellow ABS light stay on. And with this my Speedometer only works after 25 mph. Does anyone have any advise as to what this could be. I have the factory manual but so far I haven't been to keen on this book as to it's hard to figure out where subjects are found. I have a 99 2500 and I figure it's a sensor. Any info would be great.

The ABS sensor in the rear axle has gone south. Costs about $40. 00 dollars at the dealership and about a half hour to replace. There is a good thread here if you search for it which details how to replace the unit and where it is located.
