B011B closes the row with actuator S. Electrically, each actuator in the row is a coil or motor switched by a module or a relay. HELLA's relay guide explains the switching side: a control coil on terminals 85 and 86 pulls in the armature and moves the contact from 87a over to 87, and some types carry a resistor or diode across the coil to tame the spike at switch-off. Asmo's US20120266926A1 energises its camera wash valve through a relay fed from the reversing-lamp circuit, so a fault there can disable the wash as well. An open coil, a sticking relay or a broken feed on this last actuator is what B011B points to. No public source ties S to a particular camera or reports B011B from a real vehicle.

Likely causes

Coil or motor of actuator S open or shorted
Relay feeding actuator S sticking or with a burnt contact
Blown fuse or broken supply wire to the relay or actuator

Symptoms

  • Camera wash for the camera served by actuator S does nothing
  • Wash may run continuously or not stop if a relay contact has welded
