I made COMBI coding to disable SOS in our F10 tool. After a while the SOS malfunction came back. What is the procedure for SOS cancellation?

Coding list:

TCM_ALIVE_MONITOR -> nicht_activ

TCM_ID_MONITOR -> nicht_activ

You sure that this is SOS, not the battery fault (aux one in headliner) ?

KOMBI => ST_ECAL_ALIVE = nicht_aktiv
KOMBI => ST_ECAL_TIMEOUT = nicht_aktiv

You can check removing telematics via adding TELD to FA and coding KOMBI

Now SOS battery error.

Now SOS battery error.

Replace the battery then, it's not that expensive

Now SOS battery error.

replace it

would be easier and better to change the battery if its just that but if you still want to disable use the below coding


SOS full OFF !!!


KOMBI
3001 CC_ID_Sperre
CC_AKTIVIERUNG_5
XX, XX, XX, XX, XX, FF, XX, XX --> XX, XX, XX, XX, XX, F7, XX, XX

P.s.
(SOS call system failure ID = 299 )
FF byte -> bits: 1111.1111
F7 byte -> bits: 1111.0111
