I have already gone through the Insite trouble shooting chart. I have no power at the NoX module at the in or the out side. I cant locate the relay or the circut breaker/fuse. Is this built into the ECM.
Expert:  cumminsdr replied 1 year ago.
No it is a fuse/relay box either in the engine compartment or the master fuse box in the cab. In the the engine compartment look for a fuse block that indicates the aftertreatment system.
Customer: replied 1 year ago.
I could not locate it in or out side the truck. There is no fuse or relay marked after treatment or any thing related to the system. That would be way to easy
