U1900 controller area network communication bus malfunction receive malfunction NON-MIL

do you have an abs light on or check traction control?

if not clear them.

if they dont stay cleared, get abs module PMI with an ids.

if it can't be PMI ( does not accept programming)you need a new abs ecu.

no lights were on ... not even the CEL i just randomly plug in the scanner and found them but yes i cleared them

and triton did your truck run a little rough when you had the codes? mine seems to have a little hesitation and a little (very little) skip at idle

I can't quite remember, I had a lot going on with the truck in one month. Had the fuel rail pressure sensor code, cyl 1 misfire, C02 code (due to catback), and then the codes you listed.

Whenever I get a code that relates to something that isn't easy to check on my own real quick, I just reset it and then if it comes back I will worry. Not much you can do in your case because when I searched those codes I found a lot of possible problems and none of them were anything that I knew anything about.
