B012FA/V Sensor Washer Fluid A Control Circuit
- Generic OBD-II code · Body
- How the car detects it
- B012F reports a fault in the control circuit for A/V sensor washer fluid A, the first of six such circuits, with B0130 to B0134 following. A/V most likely stands for autonomous vehicle; the circuit drives the pump or valve that delivers fluid to one sensor. Uber's patent family (US20180015907A1, US10220817B2) shows the layout: one reservoir, a set of pumps the vehicle computer starts individually for each camera or lidar cleaner, plus compressed air through solenoid valves. Ford's US10569746B2 has the computer run a wash pump when it judges a sensor window dirty. Which sensor A serves is not published; no maker documents B012F. If the circuit fails, sensor A goes uncleaned and automated driving functions may restrict themselves.
- What you may notice

- PossibleDamaged wiring or corroded connector in the control circuit
- RareDriver stage in the controlling module defective
