B011A code meaning
Camera Washer Actuator R
What B011A means
B011A covers actuator R. Some camera cleaners use air as well as fluid, so the actuator may be a blower as much as a pump. Thunder Power's patent US9539988B2 places a water nozzle and an air nozzle at a reversing camera: air blasts first, then unheated fluid, and below about 0 °C heated fluid, while an infrared drop sensor behind the lens decides when cleaning is needed. Denso's US9180840B2 opens its fluid valve only after the air has started and keeps it open for 0.1 to 0.5 s; in its tests at least about 70 % of salty mud had to come off for a usable picture. Air blowers for sensors have their own codes from B0100. Which camera R serves is not published; no manufacturer documents B011A.

What to do next
- Note B011A and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
