Okay so my check engine light is on, so I went to check the codes with the key trick. All that came up was "P doNe". Went to the parts store and had them scan it, nothing came up besides "Base Brake Incident Abs 78". The guy at the parts store said he has no idea what or how to find out what it is and told me to go to the dealer. I have already reset the pcm and that did nothing after about 20 miles it comes back. No ABS or brake lights are on the dash. The only reason I care so much is cause in order to pass emissions the MIL cant be on. Any help is great. Thank you.

 

Never heard of this, however a person an a different site in a Ram had this issue and the braking CAB was bad and was replaced to fix the issue. Now this sounds very plausible. I would tell you to have yours rebuilt. There are threads on here that will tell you where to go.

Also try to bleed the bakes as it could be a pressure variation between wheels.

Good luck!
