Causes
- Open or shorted wiring in the actuator K circuit
- Poor or corroded connector(s) to the actuator
- Failed camera washer motor/actuator (seized or electrical fault)
- Blown fuse or faulty relay in washer circuit
- Washer pump clogged or mechanically jammed
- Body control module (BCM) or camera module fault
Symptoms
- Front camera washer does not operate when requested
- Camera image contaminated by dirt, causing ADAS/warning messages
- DTC B0113 stored in body/camera module and possible warning lamp/message
- Washer operation intermittent or only works sometimes
- Unusual noise or no noise from washer pump/actuator when activated
What to check
- Visually inspect washer reservoir level and fluid quality
- Inspect wiring and connector to camera washer actuator for corrosion, damage, or loose pins
- Check associated fuse(s) and relay(s) for continuity and correct operation
- Command washer from vehicle diagnostics and listen/observe actuator operation
- Check for physical blockages at nozzles and pump inlet
- Scan for additional related DTCs (camera/washer/BCM)
Signal parameters
- Supply voltage to actuator when commanded: ~battery voltage (nominal ~9–14 V)
- Ground continuity to chassis ground when commanded
- Actuator current draw: typically low-medium (motor load) — significant increase indicates mechanical bind, near-zero indicates open circuit
- Control signal may be switched 0 V / battery or PWM depending on manufacturer; expected change when commanded
Diagnostic algorithm
- Retrieve freeze frame and all related DTCs from camera, BCM and body modules. Note whether the code is current or historic.
- Verify washer fluid level; top up if low and re-test. Inspect nozzles and pump inlet for blockage.
- Visually inspect connector and wiring to the camera washer actuator. Repair any chafed wires, corrosion or loose terminals.
- With connector disconnected, check for supply voltage at the actuator harness while commanding the washer on. If no voltage, follow supply back to fuse/relay and BCM.
- Check ground continuity from actuator ground pin to chassis ground. Repair poor grounds.
- Measure resistance of the actuator motor (reference vehicle-specific spec). Open circuit suggests failed motor; very low/high or inconsistent resistance suggests internal failure.
- If supply and ground are present at the connector but actuator does not run when connected, replace actuator assembly.
- If wiring and actuator are good but no control signal from module, test or reprogram the controlling module per manufacturer procedures or consult wiring diagrams; replace module only after confirming wiring/actuator fault is not present.
- Clear codes and re-test multiple cycles; verify no recurrence and camera/ADAS functions restored.
Likely causes
- Damaged harness near hinge, bumper, or washer pump assembly
- Corroded pins or water ingress at the actuator connector
- Actuator motor bearings seized or internal electrical failure
- Blown related fuse or sticky / failed relay
- Foreign debris blocking nozzle or pump suction
- Intermittent ground or poor power feed to the actuator
