F9C4 is CAN messages not being received by the ECM

9A3 is monitor fails to receive power configuration message

Thoroughly inspect the wiring harness and connector pins for damage and corrosion to the machine ECM. CAN bus faults are the most difficult to diagnose. Sometimes they are easier to find than others. but this is a communication error to the ECM. Let me know
