JR Durazo Posted May 29, 2019 Share Posted May 29, 2019 I am looking for the wiring schematic for this unit. No throttle response. Active Cummins codes for throttle low voltage. Was able to identify that Engine is not directly wired to accelerator pedal. Unit has new accelerator pedal and an engine ecm and vecu have been put on from a sister unit to test. Would like to look at proper wiring schematic to test resistances and voltages. Thank you in advance if you can help with this information.
