Check engine lightUsually off

B0106 opens a row of four lidar washer actuators (A to D). The actuator is whatever delivers fluid to a lidar window: a washer pump or an electromagnetic valve. In Ford's patent US10569746B2 a computer triggers a wash pump for the spray nozzle of a roof lidar, after an air nozzle has run for about 5 s and the window is still more than about 20 % opaque; a wiper follows only if needed. Solero builds 2/2- and 3/2-way valves that send washer fluid to individual nozzles, including lidar. AUMOVIO's lidar nozzles clean the dome with pressurised liquid using the Coanda effect. Which lidar or nozzle the maker calls A is not published, and no carmaker documents B0106. When the wash fails, the lidar may report a blocked view.

Likely causes

Washer pump or valve A for the lidar nozzle seized or electrically open
Wiring or plug fault at actuator A
Frozen washer fluid blocking pump A

Symptoms

  • No spray reaches lidar A during a cleaning cycle
  • Lidar blocked message and reduced automated driving availability
