B0115 names actuator M. Where several cameras share one pump, the actuator is often a distribution valve. Solero's SCV43 is a 4/3-way valve switched by voltage, with one inlet and three independently switched outlets, so a single pump can serve up to three nozzles and fewer DC pumps are needed in the reservoir. Kautex's Allegro systems clean several camera points and lidar with water and air, and their software decides which point is served first. With a shared valve block, one failed coil can stop washing at one camera while the others still spray, and that is how a single-letter code like B0115 would show. No manufacturer publishes B0115 or the camera behind M.

Likely causes

Coil for outlet M in a shared valve block open or shorted
Valve M stuck by deposits or frozen fluid, drawing abnormal current
Wiring or plug fault on the line to valve M

Symptoms

  • One camera stays unwashed while other cameras on the same pump are sprayed
  • Camera blocked message for that camera in bad weather
