You should be able to find these on Bing.com or Google.com This is what
I got off of Bing.com, hope something here helps P1342 brake controller
can now be fixed, check it out on Youtube. Goodluck.
U1900 deals with #11 fuse. could be plugged in wrong, symptoms with
cruise control inop
The P0403
It sounds like you have a broken or cracked turbo inlet pipe,this is the
pipe setup from the engine to the turbo,they both have a flex joint in
them that cracks and leaks exhaust under the hood,this reduces the
turbo boost pressure and allows the engine to suck exhaust fumes
back into the aircleaner.The P0403 is an EGR code,this usually means
the EGR valve is sticking open,which will also reduce boost pressure
and cause it to run really bad. Both of these problems will effect fuel
mileage drastically.
B1342
The B1342 is an internal failure in the tbc. The tbc is considered a stand
alone module that is why it can set codes. To repair the trailer brake
system you will need to replace the trailer brake controller itself. It will
simply plug and play so you can get a used one if you would like. I'm
not sure if there is anyone that repairs these or not. I will see really quick.
