I have this 2015 Ram 1500 Big Horn, on which I installed aftermarket mirror signals and now they hyperflash. I tried going into AlfaOBD to turn off the bulb-out detection, but the option doesn't show up under powernet settings. Does anyone else run into this with 2015s? Did Ram move it or hide it somewhere?
 
Yeah, 2015s can be weird like that. Sometimes the setting shows up under "Body Computer" instead of "PowerNet," so try digging there.
 
Check for it under the body computer > exterior lighting section instead of Powernet, if it's still not showing, you might need to update your BCM firmware or check your connection setup. Worst case, adding resistors might still be the fallback if the software mods won't stick.
