Re: 2012 c15 gen set engine

Sorry about the autocorrect. Fmi 31 external shutdown switch active. It was previously used in a gen set application and I don't have the own wiring.

2012 c15 gen set engine

I have a 2012 C 15 cat engine that was removed from a gender application. We are trying to get this engine to run on a stand as a trainer but are getting a code for a SPN 970 FMI 30 1X ternal auxiliary switch shut down activated. How can we bypass this in the ECM so that the engine will run without that switch present ?
