trr Posted September 6, 2020 Report Share Posted September 6, 2020 Hi. I have a 2014 Edge and all of a sudden my headlights won’t come on, neither of them. And when I turn the brights on I heard a hard clicking sound and they don’t come on either. I did a little research and i found that it might be the body control module needs resetting? Help!

WWWPerfA_ZN0W Posted September 6, 2020 Report Share Posted September 6, 2020 Check for codes first. You should use a scanner that reads both HS-CAN and MS-CAN buses. May be a fault in the FLM (headlight switch) or something deeper. The clicking is the shutters that change the headlights from "low" to "high" mode, can you see them move at all? Do you have manual or auto headlamps? 1 Quote Link to comment Share on other sites More sharing options...
trr Posted September 6, 2020 Author Report Share Posted September 6, 2020 I have auto, but they won’t come on if I switch to manual. I haven’t checked to see if they move, I will. I ran my scanner and It didn’t return any codes. Thanks for responding! Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 6, 2020 Report Share Posted September 6, 2020 hid or halogen? did you change from halogen to hid/led? changing from halogen to hid especially in some cases can cause the BCM to overload, probably a protection transistor or diode that blew. The FLM/headlamp switch could still be at fault. While moving the headlamp switch through all positions, monitor the FLM headlamp switch input PID (LT_SW). Do the headlamp switch positions agree with the PID? Yes GO to C4 . No INSTALL a new FLM Quote Link to comment Share on other sites More sharing options...
trr Posted September 7, 2020 Author Report Share Posted September 7, 2020 They are the original headlights... I’m not sure what the PID is thanks Quote Link to comment Share on other sites More sharing options...
trr Posted September 7, 2020 Author Report Share Posted September 7, 2020 The switch turns on the driving lights, when you go to the next position, headlights on, nothing. And then to Auto on, nothing as well Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 7, 2020 Report Share Posted September 7, 2020 The switch may be blown. PIDs are how module functions are monitored. You need an OBD II adapter + Forscan Lite software to monitor PID data. Plug the adapter into the OBD port under the dash, load up the software on your smartphone/tablet, connect the software to the adapter, add a PID to monitor data (in this case, the PID is LT_SW). Check to see what the PID states each time you change the position of the switch. It should correspond. There are videos on YT on how to set up and use Forscan Lite, if you want to do this.
