Hi everyone

I got a 3 stop front and rear opening Schindler 2007 hydro .. I think Its a 330a or EIB.

After a double reset it will accept a call and take off. It will land and the doors will open and close but it will be shut down on a 0121 extra info all 0 until 7B at the end. I don’t see 7B extra info on my fault list. But i do see 78. Any help on this would be great. Also if I stop the car mid flight with controller inspection it will also throw the 0121 fault after I turn it back on normal operation

Note .. top of car switches look good. All lights go on and off as I wave my hand through the horseshoes . KLU AND KLD both are lit back on controller as it stops at the floor
