What it means

B011A is defined as a fault in the Camera Washer Actuator R circuit or operation. The control unit that drives the camera lens washer saw an electrical fault, such as an open circuit, short circuit or no expected response, when it commanded the actuator on the R side. The R is normally right or rear depending on how the manufacturer labels the camera, so check the vehicle documentation for which one applies.

Symptoms

Camera washer does not spray when the cleaning function is used
Camera image stays dirty or smeared after a wash request
Warning message about camera cleaning or a blocked or dirty camera
Parking, surround-view or driver assistance features limited or unavailable
Washer fluid sprays continuously or in the wrong place

Possible causes

Faulty camera washer actuator, pump or pop-up nozzle unit (seized, blocked or failed motor or solenoid)likely
Damaged wiring, corrosion or loose connector at the actuator or in the nearby harnesslikely
Blocked or frozen washer fluid line, nozzle or filter, or empty washer reservoirpossible
Blown fuse or faulty relay on the washer or camera supply circuitpossible
Fault in the controlling module output driver or its supply and earthrare
Outdated or faulty module software where the manufacturer has issued a fix for this faultrare

How to diagnose

Read all stored and pending codes and note any related camera, washer or supply voltage codes, then review the freeze frame data if available
Check the washer fluid level and top up with suitable fluid, then check that the main windscreen washers work
Operate the camera washer using the normal control or a scan tool actuator test and watch and listen for the actuator working
Inspect the actuator, hoses, nozzle and connectors for damage, leaks, blockages, corrosion, water ingress or frozen fluid
Check the relevant fuse and relay, as shown in the vehicle wiring diagram
Check the actuator supply, earth and control signal at the connector with a multimeter, following the manufacturer procedure
Test the wiring for continuity and shorts between the actuator and the control unit; the layout depends on model
Check for software updates or technical service bulletins for this vehicle once the hardware is proven good

How to fix

Replace the camera washer actuator, pump or nozzle assembly if it is faulty or seized
Repair or replace damaged wiring and clean or replace corroded connectors
Clear blocked or frozen lines and nozzles, replace damaged hoses, and refill with correct washer fluid
Replace the blown fuse or faulty relay after finding out why it failed
Replace or repair the controlling module only after the wiring and actuator are confirmed good
Update the module software if a manufacturer update addresses this fault

Can I keep driving?

Low severity

The car can normally be driven, but the camera lens may not clean itself and camera-based aids may be reduced. Wipe the lens by hand when it is safe to do so and book the repair in.
