2015 Spartan Lion w/Cummins ISB
Hi all, I am new here. I am a mechanic working on a remote construction site in northern Manitoba, Canada. I am responsible for a small fleet of pickups and buses. My 2015 Spartan is driving me nuts. It starts just fine, but has zero throttle response. I do not have access to a scan tool. I did find a burned relay in the fuse panel which I replaced to no avail. Does anyone know where I can find an online wiring diagram and/or service manual? Any help is greatly appreciated. Thanks in advance.
