OBD-II fault code

B0115: Camera Washer Actuator M

What it means

This code identifies a fault associated with Camera Washer Actuator M. The code alone does not specify the failure mode.

At a glance

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

How it works

Camera Washer Actuator M controls a camera washer mechanism identified as M in the vehicle's system. The control module checks the actuator circuit when it issues a washer command; this code indicates a problem linked to M but does not state the failure mode.

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. Record freeze-frame information and any related body-system codes with a scan tool, then command actuator M where possible to see whether it responds.
  2. Use vehicle-specific wiring information to locate the M actuator, then inspect its connector, wiring, washer line, and nozzle for corrosion, damage, leaks, or blockage.
  3. Check the relevant fuse and verify power and ground at actuator M while it is commanded.
  4. Test the M circuit for opens, shorts, and intermittent connections, including while moving accessible sections of the harness.
  5. If electrical checks pass, check the M mechanism for binding and test the actuator against the manufacturer's specification.

Common fixes

  • Clear an obstruction from the M washer path or nozzle.
  • Reconnect or clean the actuator M connector and repair chafed or broken wiring.
  • Replace a failed fuse after checking the circuit for the reason it opened.
  • Replace a camera washer actuator M that does not meet the manufacturer's specification.
  • Repair a defective driver circuit if the M actuator, fuse, and wiring test correctly.

Can I keep driving?

You can usually continue driving if the camera view is unobstructed, but the washer function assigned to actuator M may not clear it. Keep the lens clean and take extra care if that camera is needed for visibility or safety features.

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.
