Having an issue. Trying to figure out which code is tripping the message on the EVIC.
I know B1630, U0200, U0199 is my doing
For C107C, I replaced my brake switch (Stuck 1/2). That possibly couldn't have fixed it.
What are codes B2185, U0156 (Both in the FCM). I think B2185 could be ignition related. I tried searching for U0156, no luck there.
Truck runs fine, Service 4WD pops up here and there. When the light is on, cruise control works still (Checking Brake Switch). More than likely a dirty connection somewhere or a chaffing wire. Anybody have any diagrams?
