"I have a 2015 VNL 780. When I turn on the ignition key (motor not started) I can\nturn on the work lights (back of cab) and they function properly. When I start\nthe motor, the work lights will only turn on momentarily (.5 seconds) then turn\noff. I also get an error code for the light control module: MID 216 PSID 57 FMI\n6, which indicates a ground fault. When I turn the motor off, the lights work\nnormally. When I turn the battery switch off then back on, the error code\nclears. Any suggestions about where to look for the short or what might be\ncausing the issue?\n\n\nMechanic's Assistant: Can you turn the steering wheel at all? And what about the\nkey? Is it worn or damaged?\n\n\nEverything else works fine.\n\n\nMechanic's Assistant: Are you fixing your Volvo 780 yourself? What have you\ntried so far?\n\n\nI am working the problem myself. I have pulled the switch and replaced it, same\nproblem. Voltage to the hot side seems low when checking with a multi-meter.\n\n\nMechanic's Assistant: Anything else you want the Mechanic to know before I\nconnect you?\n\n\nNo other issues at this time."
