B0130A/V Sensor Washer Fluid B Control Circuit

  • Generic OBD-II code · Body
How the car detects it
B0130 reports a fault where the module switches A/V sensor washer fluid B, the second of six channels running from B012F (A) to B0134 (F). A/V almost certainly stands for autonomous vehicle. Uber's cleaning layout (US20180015907A1) shows what such a channel switches: a compressor charges an air accumulator, one reservoir with a level sensor holds the fluid, and several pumps feed the cleaning heads, each started separately by the vehicle computer. Kautex sells its Allegro system for cameras and lidar on vehicles from level 1 to level 5, mixing water and air jets. Which sensor channel B serves is not published, and no carmaker documents B0130. With the circuit open or shorted, the sensor on channel B is no longer washed.
What you may notice
  • The camera or lidar on channel B stays dirty while the others are cleaned

Likely causes
  • LikelyPump motor or valve coil on fluid channel B open or shorted
  • PossibleCorroded or loose connector at the pump, exposed to washer spray and road salt
  • RareOutput stage for channel B in the controlling module failed
Repair
Medium · Often possible to do yourself.Typical cost: €30 – €400
