B011EFluid Reservoir Level Sensor C
- Generic OBD-II code · Body
- How the car detects it
- B011E covers level sensor C. Vehicles that steer by camera and lidar need their own cleaning supply, and there the level reading becomes an operating condition. Uber's application US20180015907A1 shows a sensor-cleaning reservoir with a dedicated liquid level sensor reporting to the vehicle computer; below a threshold the computer lights an indicator or tells a remote operator to refill. The related patent US10220817B2 adds a compressor and solenoid valves and handles pressure and fluid readings beyond their limits in the same way. Whether reservoir C is such a cleaning tank is stated nowhere, and B011E appears in no public manufacturer document. A fault leaves the system unsure whether it can still clean its sensors.
