922.7 7g failure c426 start enable drive authorization system not issued

[nano2017]

Hello,


updated software on engine ecu and zgw without any problems with star diagnosis on mercedes cls 350 w219 from 2005.
The flashing processes are completed succesfully without any errors.
The engine ecu and zgw are not scn coded, only flashed with new software.
The 922.7 gearbox had already the newest software and was not updated or scn coded.
After this flashing procedures there is a fault on egs2 722.9 gearbox: c426 start enable drive authorization system not issued.
Star diagnosis tells that this is a can communication failure between gearbox and engine ecu..
The car sometimes do not crank or the engine start and goes out in position P or N.

Can anybody help what to do ?

best regards
