So today headed to check cows the darn abs and brake lights out....noticed I have a inner front u joint out pretty sure that's the abs & brake light issue,but I also got the po 0230 code? I have the fass ddrp with about 20psi idling and around 10-12psi cruising. What gives am I about to buy a injector pump and inner wheel bearings or should I just disconnect the fass and clean the connector??? Could the code just be there because of the vss code because I have not check engine light just the abs an brake..............

 

For what its worth two front inner u joints and a passenger side wheel bearing later no abs and no brake lighjt,as for the other code put a new relay in per the techies at fass and all seems well I still have great fuel pressure so hell with it.

 

I know on the 1500's the brake and abs light could be triggered by a dirty sensor on the rear pumpkin.. but not sure if it's the same on the cummins
