Forscan DRL alternative light changes not being accepted during BCM module write process. 2019 Eco Premium.

[MustangOldtimer]

My BCM rejects Fog Lamp and Dedicated DRL with 'Writing blocks failed – incompatible configuration.' Current values are:

• 726-45-01 = AA00 4100 00BE
• 726-50-01 = 40BE
  Has anyone with a 2019 EcoBoost Premium LED car unlocked alternate DRL choices? Looking for the verified 726-45-01 value
  
  

If someone has done this exact change, and can either help with how it was done, or point me in the right direction, I would be very grateful. I just want to turn the foglights on with my signature lights...but although my BCM exposes the alternate DRL modes, it rejects them because the restriction is still active'

TIA!
