Code B0116 indicates a malfunction in the circuit for the camera washer actuator, which is the component responsible for spraying washer fluid onto the vehicle's camera lens. This code is set when the body control module detects an electrical issue—such as an open, short, or out-of-range signal—in the actuator circuit designated 'N.' The camera washer system helps maintain visibility for surround-view or rearview cameras in adverse conditions.
The actuator or pump motor itself can fail internally, preventing it from operating when commanded.
Damaged, corroded, or chafed wiring to the actuator can cause an open circuit or short to ground/power.
Corroded, loose, or backed-out pins at the actuator connector can interrupt the circuit.
A blown fuse in the camera washer circuit will prevent the actuator from receiving power.
A physical blockage can cause excessive current draw or make the system appear inoperative, though this typically sets a different code.
Internal BCM driver failure is extremely rare for this code and should only be considered after all other causes are eliminated.
The definition is universal; the diagnostics are engine-specific. Open your vehicle for the codes documented for it:
Yes, the vehicle is safe to drive. However, the camera lens may become obscured in mud, snow, or rain, reducing visibility when parking or maneuvering.
Almost never. Replacing the BCM is a common misdiagnosis for this code. The root cause is overwhelmingly the actuator itself, a wiring issue, or a connection problem. The BCM should be the absolute last component suspected.
In most vehicles, yes. The camera washer has its own dedicated pump or actuator, even if it shares the same fluid reservoir. This is why the windshield washers may work fine while the camera washer does not.
You can manually clean the lens, but it will quickly become dirty again while driving. The washer is designed for on-the-go cleaning, and some safety or convenience features may rely on a clear camera view.
