Hey yall, TCU is losing can communication with the infamous 91.9 ecu and 609.9 sdu codes. Dont have the serial number for this dozer, it's got a 4.5L power tech in it. I have access to the fuse panel, but it doesn't have a cover on it to show what fuse goes to what. Can anyone send me a fuse diagram? Can anyone send me a wiring diagram of the CAN lines as well/pin out diagram? For reference, here is a picture of what the fuse box looks like pulled off another post
A picture of the one that's on this dozer:
Im dumb, the fuse panel has the list
Will need the machine's complete serial number for any schematics.
