L322 pdc sounder off code 010c

have some dtcs on park aid. Left middle sensor had a code. Now changed. ll sensors ok now. Have a faultcode 010c front sounder off. Does this tell me that sounder is disconnected or it is turned off in ecu menu? When i activat pdc button it lights on. When putting gear in reverse i have alarm from rear sensor in luggage department. If i turn pdc on and go near rear sensors ,no alarm. All sensors are ticking.

Disconnected battery and reset and everything worked.

still workin
