Hello, my name is***** will assist you.

You have one of two issues, a shorted wiring harness on the engine, or there is a short inside the EMM. Start with doing a through inspection of the wiring harness, looking for any place that may be melted or fused together. If the harness is good, the EMM will need to be sent off for repair.
