otis mcs22m 0300DBP:dfc_SE

Hello. I have a problem on MCS 220m . If the doors open the controller gives dfc_SE error. Also DOL not lits when the doors open. But if the doors stay closed no problem.


Door learning made.
Rsl prints conrolled.

What can cause this problem.

Car has 2 doors.

Faulty 1LV / 2LV / LVC relays... Replace all of them...
