Wifes daily driver ('05 Montero), she mentioned last night the on her way home from work both headlights quit working (didn't come on).
Initial diagnosis: High beams work fine, factory fog lights work fine when headlight switch is on Low Beam & turn off on High beam - this is normal, rear lights and brake lights work normal.
Inspected fuses both under dash and in engine compartment - They are OK.
Reviewed wiring diagram in FSM - appears that there is a ECM that has some function with the lights, it resides in the engine compartment fuse box. Part number MR587816. Is there a test procedure for this unit? Don't see one in the FSM. Anybody know if this unit actually controls the headlights?
Anybody else ever have this issue and resolved it?
