PROBLEM
The engine interface harness needs to be inspected on certain C1.7 and C2.2 Industrial Engines. It has been identified that the wiring schematic that may have been used to manufacture the harness had an error that can lead to the fuel pump and starter motor energizing (if the main power feeds/grounds to the ECM are disconnected, but the key switch is ON) causing the engine to start cranking. This may, in conjunction with other factors or circumstances, result in a risk of personal injury or death.
