B0117 names actuator O; unlike I, the letter O is used in this row. Not every silent washer is faulty. Continental's patent US11673532B2 (granted 2023, now held by Aumovio) lets the controller hold back the camera valves on purpose: in an off-road mode only selected cameras are washed, and with four-wheel drive engaged below about 20 km/h all valves stay shut so mud does not use up the fluid; a timed mode washes at most once per interval, two or five minutes in the examples. AUMOVIO also clears dust with air alone to save fluid. A deliberately inhibited actuator should set no code; B0117 indicates a fault in actuator O itself. Which camera O means is not published, and no manufacturer documents B0117.

Likely causes

Valve or pump O open, shorted or seized
Wiring to a low-mounted camera actuator damaged by mud, water or off-road use
Module software or configuration fault in actuator O control; update per maker

Symptoms

  • Camera stays unwashed also in normal road mode, not only when washing is intentionally paused
  • Camera blocked message in mud or rain
