Halo.I have a similar problem in kuga2009.After replacing the instrument cluster, I coded two keys.The car won't start.There are two mistakes>B1681 P1622-71.I think I mixed something up badly while initializing the modules .The errors are the same as those of the colleague above.please help.

Did you do a pats system initialisation?

[krzys2008]

I was in „RKE programming remote opening and starting the keyless system“, I deleted and re-registered two keys,
then I went to the initialization function-
remote control function actuator
-electronic steering lock
-drive system control module
-2 or more
I chose everything because I didn't find what I mentioned, i.e. IC

Hello.
Thank you Forscan for your help.The problem was solved.I connected the old IC module,despite the various lights flashing I managed to remove the error code-P1622-71 he was the one who didn't let me start the car.after connecting the new IC and deleting the codes, the car starts.there is only an error in IC-B1681-60.but it doesn't bother me.Thank you
