I would be interested in how you're planning to and actual implementation of code the brake lights to strobe.
By the "Diagnostic screen is that the intravee or for emissions faults?
Diagnostic screen: the intravee log viewing screen, live
Brake force display, from here
For an LCM.C19 module there are:
BFD_OPTION = aktiv / nicht-aktiv
There are also:
BFD_MINDEST_GESCHW - no options
BFD_STUFE_2_VERZOEG- no options
BFD_STUFE_2_MAX_EIN- no options
The cluster (mine is a KMBI_E38.C12) also has:
BRAKE_FORCE = aktiv / nicht-aktiv
BFD_AX_REF_SCHWELLE - BFD brakeforce threshold with 2 options
BFD_HYSTERESE - no options
BRAKE_FORCE_2 - aktiv / nicht_aktiv
BFD_AX_REF_SCHWELLE_2 - BFD brakeforce decel "threshold 2" with 2 options
I think we can confidently presume the base BFD is ABS and "2" is decel activated as w/ the E46.
