I have an 04 1500 4x4 5.7L. I got a used B&G Performance PCM (Computer). It was pulled from an 05 1500. I installed the PCM and everything works fine. The only thing is the ABS light keeps flashing? What does that mean? What would cause this? How do I fix this?

I have tried looking everywhere on here and Goole search, But have not been able to find any issue like this. Thanks for your time and any help would be appreciated.

 

My guess is the ABS needs to be reset. I had the same problem when I used a DSP tuner. I had to take mine to the dealer to have the ABS reset.

 

Thanks redtruck for the reply. Is there anyway to reset the ABS without going to the dealer? They will charge me 100$ "I am guessing" for two min. of work.

 

Not that I could find. The dealer charged me $35 for the ABS reset and another $35 for updating my PCM which they didn't do correctly. There is no way to win with these folks. Good luck...
