OBD-II code B0112 indicates a fault with the Camera Washer Actuator 'J' circuit, which is responsible for spraying washer fluid to clean a vehicle's rearview or surround-view camera lens. This code typically signals an electrical issue, such as a short, open circuit, or a malfunctioning actuator.
The actuator itself may have failed due to wear, internal electrical issues, or mechanical blockage, preventing it from spraying fluid.
Wiring harnesses or connectors leading to the actuator may be damaged, corroded, or shorted, disrupting the electrical signal.
A blown fuse or malfunctioning relay in the camera washer circuit can prevent power from reaching the actuator.
A blockage in the nozzle or an empty washer fluid reservoir can mimic an actuator failure, though this typically does not trigger B0112.
The switch or control module sending the signal to activate the washer may be malfunctioning, though this is less common.
While extremely uncommon, a fault in the control module responsible for managing the camera washer system could trigger this code. This should only be considered after all other causes are ruled out.
The definition is universal; the diagnostics are engine-specific. Open your vehicle for the codes documented for it:
No, the Powertrain Control Module (PCM) or Engine Control Module (ECM) is almost never the cause of B0112. This code typically points to a fault in the actuator, wiring, or related components. Replacing the PCM should only be considered after all other potential causes have been thoroughly ruled out.
Yes, this code does not affect the drivability or safety of the vehicle. However, the camera lens may become dirty or obscured over time, reducing visibility for features like rearview or surround-view cameras.
If the camera washer is not working but no code is set, the issue may be mechanical, such as a clogged nozzle, empty fluid reservoir, or a disconnected hose. Electrical issues like a faulty switch or relay may also be the cause but may not always trigger a code.
Yes, you can manually clean the camera lens with a soft cloth and mild cleaning solution if the washer system is not functioning. Avoid using abrasive materials that could scratch the lens.
