ABS light unidentifiable?

I have a 2000 ford ranger 4x4. I have an abs light on and have tried my code reader on it… My reader is supposed to read and codes and I had it set on the right program. Anyways, it said no codes stored on the module. So, I borrowed a friends and it said the same thing and so did the parts store. Any ideas on what's going on and why? I may ought to take it to the dealer.

The scanner you are using is for the OBDII system. It has to do with the emissions of the car. The ABS has nothing to do with the emissions, so off course it's not going to give you any reading. More then likely it's the sensor going bad. Just replace it and don't waste your money taking it to a dealer.

If your code reader is for a laptop, try using a piece of software called Forscan. This should access the ABS module, though you may need to use a modified Elm327 interface.
