Hi, 2008 nissan pathfinder s 99800 miles installed hid light fog light h11 with ballast but no relay 3 days ago, but now I have a code p0605 could that be the problem or the ecm is gone thanks

Possible causes:
-Engine Control Module (ECM) may be faulty
-ECM harness power supply circuit is open or shorted
-ECM harness ground circuit is open or shorted
