Attached is a schematic of the headlight circuit.

Turn headlights on.
Use a fuse wire to ground Red/White sire at the headlight bulbs. If low beam works, check the continuity between the headlight bulb and DRL control module, terminal 1C.
If continuity is good, ground the wire and if headlight comes on, you have a fault with the DRL control module.
