Is problem only with low beams? Have you replaced headlamp driver module?

No yes
Expert:  Dan replied 3 months ago.

So neither hi or low beams work? Do hi beams work when you use the flash to pass option? Thanks.

Customer: replied 3 months ago.
Only low beam do
Expert:  Dan replied 3 months ago.

The headlamp driver module is only for low beams. If hi beams aren't working, have you tried to replace the hi beam relay in location 34 of fuse box?

Unplug the body control module and ground the black/white wire at pin 7 of connector 1. Let me know if that turns on hi beams. Thanks.
