B0108LIDAR Washer Actuator C
- Generic OBD-II code · Body
- Can trigger limp mode
- How the car detects it
- B0108 covers lidar washer actuator C. Robotaxis with several lidars, for example on roof and corners, are where a third circuit would fit. Valeo lists a heated telescopic lidar nozzle, a 2021 PACE award finalist, and says it supplies cleaning systems with ECU and software for private cars and robotaxis; a telescopic nozzle adds a moving part that can stick in frost. Solero's 4/3-way valve distributes fluid centrally so fewer DC pumps are needed, meaning actuator C may be a valve position rather than a pump. Jalopnik noted in 2018 that Waymo cleaned its lidar domes with small wipers and that Cruise was building its own cleaning hardware. No manufacturer assigns C publicly or documents B0108.
