Got my truck serviced from dealership and now my headlights wont turn off?

[MValdez]

Got my truck back from dealership 2 days ago and my headlights run during the day. -Been through my settings and if my truck is running the headlights run. Someone's gotta know how to troubleshoot this. I do not want to have to bring my truck back to the dealership if I can avoid it.

Daytime running lights or DRL. You can turn it off in the settings unless your country or state requires them then it would not show. Only other option is to use something like AlfaODB to modify the settings.

They might have installed a software update that messed with your settings. Perhaps headlamp delay is set for a minute after engine off or something.

There was another thread about a BCM setting that affects headlights. Perhaps a flash at the dealer changed this setting (Tunnel detection).

Go into Settings on the radio, go to lighting and toggle DRL there?

I've been through all possible settings. This has only happened after my truck was serviced by the "professionals" at dealership last week. Hasn't been an issue for the last 3 yeas till..
