B0110 indicates a malfunction in the camera washer actuator (the motor that moves the windshield washer spray to the rear‑view camera). The powertrain control module has detected an abnormal voltage or resistance in the actuator circuit.
The motor that drives the washer nozzle for the camera has failed electrically or mechanically, causing an out‑of‑range resistance.
Wire harnesses running to the actuator can suffer corrosion, chafing, or broken pins, resulting in high resistance or open circuits.
Loose, dirty, or damaged connector pins at the actuator can interrupt the signal and trigger the code.
The fuse protecting the camera washer actuator circuit may be open or the holder may have a bad contact.
A rare possibility is a malfunctioning powertrain control module that incorrectly reads the actuator circuit; this is far less common than a component failure.
The definition is universal; the diagnostics are engine-specific. Open your vehicle for the codes documented for it:
No. Replacing the PCM is rarely the correct solution for B0110 and is usually unnecessary. The code almost always stems from the actuator, wiring, or fuse.
If the connector pins are dirty or lightly corroded, cleaning and reseating them can restore proper contact and often resolves the code.
The camera itself is not damaged by the code; however, without washer spray the lens can become obscured, reducing visibility until the issue is fixed.
A multimeter for resistance checks and a 12 V power source for a bench test are sufficient; no proprietary scan tool is required for basic diagnosis.
