B0115 — Camera Washer Actuator M

Generic OBD-II · all makesBody

B0115 indicates a malfunction in the camera washer actuator circuit for position 'M' (typically a specific camera, such as the rearview camera). The vehicle's body control module (BCM) or similar module has detected an electrical fault—such as an open, short, or excessive resistance—in the actuator circuit, preventing the washer nozzle from operating correctly.

Symptoms

Rearview or other camera image remains dirty or obstructed
Washer fluid does not spray onto the camera lens when activated
Warning light or message on the dashboard related to camera or washer system
Washer pump runs but no fluid reaches the camera (if separate actuator)
Intermittent operation of the camera washer

What causes it — most likely first

1. Faulty camera washer actuator motor

The actuator itself (a small electric motor or solenoid) has failed internally due to wear, corrosion, or a mechanical jam. This is the most common cause.

2. Damaged or corroded wiring/connector

The harness leading to the actuator may be chafed, broken, or corroded, especially near the trunk lid or tailgate hinge area. A poor connection can cause an open or short circuit.

3. Blown fuse or faulty relay

The camera washer circuit is protected by a fuse. A blown fuse (often due to a shorted actuator) or a defective relay will cut power to the actuator.

4. Low or contaminated washer fluid

If the washer fluid level is very low or the fluid is frozen, the pump may not deliver fluid, but this typically triggers a different code. However, it can indirectly affect actuator operation if the system uses a separate pump for the camera.

5. Faulty body control module (BCM) or wiring to BCM

The BCM controls the actuator. A rare but possible cause is a BCM failure or a break in the communication/signal wire from the BCM to the actuator.

How it's diagnosed

Check the washer fluid level and ensure the fluid is not frozen (if applicable).
Locate the camera washer actuator (often near the camera or in the rear hatch) and inspect its electrical connector for corrosion, damage, or loose pins.
Test the actuator by applying battery voltage and ground directly; if it does not operate, replace the actuator.
Check the fuse for the camera washer circuit (refer to the vehicle's fuse diagram) and replace if blown. If the fuse blows again, there is a short circuit.
Using a multimeter, verify that the actuator receives power and ground when the washer switch is activated. If not, trace the wiring back to the BCM or switch for opens or shorts.
If all wiring and the actuator test good, the BCM may be faulty. This is rare; confirm by checking for communication codes and performing a BCM output test if possible.

Frequently asked

Can I drive the vehicle with a B0115 code?

Yes, the vehicle is generally safe to drive. The code only affects the camera washer function, not the camera itself or other critical systems. However, a dirty camera lens may reduce visibility, so clean it manually if needed.

Do I need to replace the camera to fix B0115?

No. The code is for the washer actuator, not the camera. Unless the camera itself is physically damaged, you only need to repair or replace the actuator or its wiring.

Is the engine computer (PCM/ECM) likely the cause?

No. B0115 is a body code, not a powertrain code. The PCM/ECM is almost never the cause. The fault lies in the body control module (BCM), actuator, or wiring. Replacing the PCM would be a misdiagnosis.

Can a blown fuse cause B0115?

Yes, a blown fuse is a common and simple cause. Always check the fuse first before replacing any components.
