Need help understanding "New" codes in Paccar engine.

Paccar fault codes suck. I'm told that they care working on a J1939 to OBD2 conversion list, but right now, the only way to get the Paccar fault code is to hook it to Davie. I have a complete list of the OBD faults from the troubleshooting manual, but the truck is telling you a J1939 fault code. I only have a partial list that I've been building, but it's very incomplete. SPN 1231 is CAN Bus fault (which you already know), FMI 11 is "Root Cause Unknown", no help there.

I have no info on SPN 524287, FMI 31 only means "Condition Exists".

Sorry I can't help, Paccar dash faults are going to be very tough to get any info on until Paccar can build a truck that can display the faults of their own engines. Or at least a way to convert them to the OBD faults.

Some specd on your truck, VECU trucks have lots of IMHO useless codes.

PM me an email and I can send you what I have, I have quite a long list, but not complete. From what I hear, Paccar has heard quite a bit of squawking on this very subject. About 2 weeks ago, our Pete dealer said they are working on it, but no ETA. Everytime one of our truck sets a code, I match it with the Paccar OBD fault. I have 3 other friends doing the same and we share info, so the list is pretty good for common problems.
