OBD-II fault code

B011B: Camera Washer Actuator S

What it means

Fault on camera washer actuator S. The cam phaser actuator adjusts intake/exhaust timing under load — a stuck or slow phaser kills mid-rpm torque and can throw correlation codes between cam and crank.

At a glance

  • Usually lights the airbag (SRS) or body-system warning light

How it works

Camera Washer Actuator S operates the camera washer mechanism designated S by the vehicle system. The control module checks the S actuator circuit when washer operation is requested; this code indicates a fault associated with that mechanism, but does not specify whether it is electrical or mechanical.

Common causes

Most likely first.

  1. Failed camera washer actuator
  2. Open or shorted actuator wiring
  3. Loose, corroded, or damaged connector
  4. Blown fuse or faulty driver circuit
  5. Blocked or seized washer mechanism

Symptoms

  • Warning light or symbol related to the affected system
  • Comfort or safety function impaired

How to diagnose it

  1. Capture freeze-frame data and related body-system codes with a scan tool, then command actuator S if supported and note whether it operates.
  2. Locate the S washer mechanism using vehicle-specific service information and inspect its actuator, connector, wiring, hose, and nozzle for damage, corrosion, leaks, or a blockage.
  3. Check the relevant fuse and verify power and ground at actuator S while it is commanded.
  4. Test the S circuit for opens, shorts, and intermittent contact, checking vulnerable harness sections and connectors.
  5. If power and wiring are sound, check the S mechanism for binding and test its actuator against the manufacturer's specification.

Common fixes

  • Clear an obstruction from the S washer path or mechanism.
  • Clean or secure the actuator S connector and repair damaged wiring.
  • Replace a blown fuse after checking for and correcting the cause.
  • Replace a failed camera washer actuator S.
  • Repair a faulty driver circuit if the actuator and S circuit pass testing.

Can I keep driving?

You can generally drive if the camera view stays clear, but the washer function controlled by S may not work. Keep the lens clean and use caution if the affected camera is needed for safe visibility.

A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together

This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
