I don't know if your headlamps LED or halogen, the wiring diagram is for the latter. Note the fuses in diagram, underhood fuse block. Not only check the fuse, check fuse circuit for voltage, use a test light. Hopefully your owners manual will show you what and where on the fuses. Sometimes the fuse box cover may have a legend that tells which fuse is which? I'd check for headlamp trouble codes, these appear to be manufacturer specific codes, if there are any. It's my understanding, the headlamp switch sends signal to bcm, then the bcm sends voltage for head lamps. good luck
