IMMO UCH-N2


the main problem, keys doesn't work immo lamp is flasing in UCU paramerters immo is not active
i tried connect the keys by launch tester and it got an error in immo the error is DF067 Ring>decoder connection,invalid key(
i have check the ring and key with oscilloscope and they are work
in my opinion the firmware of the UCH-N2 is corrupt, eeprom there is 93c66 and ECU eeprom is 95080
i programed a virgin eeprom in 93c66 but cannot connect keys with UCH-N2 and lamp of immo dont flashing meanwhile in my own firmware it shows connection is success
May be dio You have the two files for ECU 95080 and UCH-N2 93c66 or any solutions with my car?, thank You!

Hi,
So immo flash 1 every second, turn ign on immo start to flash fast? and everything was previously paired.

remove battery earth foer a few seconds and repace. Put a jump lead on battery negative and engine block, ( engine ground on gearbox to inner wing/leg corodes.)

In fuse box nect to battery:-
1) check 3 rectangle relays in fuse box and put them back in a different order
2) replace the 3 fuses even if not blown
3) check white wire on starter terminal
4) check 2 amp fuse in end of dash
5) resolder key remote board
