Code B0107 indicates a malfunction in the actuator responsible for cleaning the LiDAR sensor (Actuator B). This typically means the system has detected an electrical or mechanical failure that prevents the washer nozzle from operating correctly.
The internal motor or gear mechanism of the washer actuator has seized or suffered an electrical failure.
Corroded, pinched, or frayed wires leading to the actuator causing an open or short circuit.
Debris, ice, or mineral buildup preventing the actuator from completing its range of motion.
A blown fuse in the washer circuit preventing power from reaching the actuator.
A failure within the body control module or ADAS controller preventing the command signal from being sent.
The definition is universal; the diagnostics are engine-specific. Open your vehicle for the codes documented for it:
Yes, the vehicle remains drivable, but safety features that rely on the LiDAR sensor may be disabled if the sensor becomes dirty.
Manual cleaning may restore sensor visibility and clear ADAS warnings, but the B0107 fault code will remain until the actuator hardware is repaired.
No. It is very rare for the control module to be the cause; the issue is almost always the actuator itself or the associated wiring.
