Hey @Ghhuff,
Trying to do this myself, bought OEM HID headlamps to convert from the halogen to HID for my 2015 ford Edge, I changed the values for 726-45-01 and 726-50-01 based on the above but for 726-25-02 xxxX xxxx xxxx to select Headlamp type from 0=Halogen to 1=HID, when I change the value to 1 for HID and write it to vehicle it says its written and has gone through but when rescanning the car after the change it reflects its still set to 0 for halogen and wont accept the headlamp change to HID. Any thoughts on if you encountered this is or if I am missing something I didnt do for writing to the module that needs to change that hasn't?
If I recall its change
726-25-02 to xxxX xxxx xxxx from 0 to 1 for HID
726-45-01 xxxx XXxx xxxx change value at XX to 7F
726-50-01 XXxx change XX value to 10
the second two changes went through no issues but not the Headlamp type.
So headlamps work fine when IGN is in ACC/ON position but when engine is on after 5 seconds HIDs just flash and go dark, which is I assume from the change not going through for HIDs for some reason.
Any thoughts or maybe I am missing something else you did? Would appreciate any help you can provide.
