B0112Camera Washer Actuator J

B0112 indicates that the body control module (BCM) or camera control module has detected a fault in the electrical circuit for the camera washer actuator J, which is typically the washer pump or nozzle assembly responsible for cleaning the rearview or surround-view camera lens. The module monitors the actuator's command and feedback circuits and sets this code when the expected current or voltage is outside the normal range during a washer activation request.

Symptoms you may notice

  • The camera washer does not spray fluid when activated, leaving the camera lens dirty and reducing visibility.
  • The washer pump may run continuously or not at all, depending on whether the circuit is open or shorted.
  • A warning light or message on the dashboard indicating a camera system fault or washer system malfunction.
  • Often no symptoms besides the warning light, especially if the actuator is only intermittently failing.
  • The camera view may become obstructed more quickly in wet or dirty conditions, prompting frequent manual cleaning.
  • Other camera-related features such as lane departure or surround-view may be degraded if the lens remains dirty.

Common causes, most likely first

  1. Failed camera washer actuator (pump or nozzle assembly) due to internal motor wear or clogging.
  2. Damaged or corroded wiring harness or connector at the actuator, often from exposure to road debris and moisture.
  3. Blown fuse or relay supplying power to the camera washer circuit.
  4. Faulty body control module (BCM) or camera control module, though this is less common.
  5. Blocked washer fluid line or nozzle, causing the actuator to overwork and trigger a circuit fault.
  6. Poor ground connection for the actuator circuit, leading to erratic operation and code setting.

How to diagnose and fix it

  1. Verify the code with a scan tool and check for any related codes in the BCM or camera module to confirm the fault is specific to actuator J.
  2. Inspect the washer fluid level and ensure the fluid is not frozen or contaminated, as this can cause the actuator to stall and set a circuit code.
  3. Check the fuse and relay for the camera washer circuit, replacing any blown fuse or faulty relay as needed.
  4. Disconnect the actuator connector and inspect for corrosion, bent pins, or damaged wiring; repair or replace the harness as necessary.
  5. Test the actuator directly by applying power and ground to its terminals to see if it operates; if not, replace the actuator.
  6. Check the ground connection for the actuator circuit and clean or tighten as required.
  7. Clear the code and test the system; if the code returns, further diagnose the BCM or camera module with a bidirectional scan tool.

Camera washer faults you might overlook

  • A clogged washer nozzle or pinched fluid line can cause the actuator to draw excessive current, setting B0112 even though the actuator itself is healthy.
  • The camera washer actuator is often confused with the windshield washer pump, but they are separate components on vehicles with dedicated camera cleaning systems.
  • Intermittent B0112 codes can be caused by water intrusion into the connector, which may not be obvious until the connector is disconnected and inspected.
  • Some vehicles require recalibration of the camera system after replacing the washer actuator, so consult the service information before assuming a plug-and-play repair.
  • A weak battery or charging system fault can cause multiple body codes including B0112, so always verify battery voltage and ground integrity first.

Can I keep driving with B0112?

It is generally safe to continue driving with B0112 because the camera washer is a convenience feature and does not affect primary vehicle operation. However, be aware that a dirty camera lens may degrade advanced driver assistance systems, so clean the lens manually if needed and avoid relying on camera-based features in poor visibility until the fault is repaired.
