I have a brake and abs warning light that stays on after startup. The guy I bought the truck from says he took it to a Dodge dealer to have a diag. done and they could not figure out. I have done some reading and am finding out that it might be the VSS. Can you shed any light on what I can do to fix this problem?

Thanks

I would be more likely to believe that it would be a ABS sensor on one of the wheels. The VSS will likely cause an odd transmission shift.

The VSS on the rear diff is your ABS sensor. My truck is doing the same thing, leading me to believe the combination valve or RAWL valve on the master cylinder is bad.
