Causes
- Open or short in the actuator wiring harness
- Poor or corroded connector or terminal at the actuator
- Failed washer actuator motor (internal short or open)
- Stuck or mechanically jammed actuator/nozzle
- Blown fuse or faulty relay supplying the actuator
- Faulty body/control module output driver
Symptoms
- Camera washer does not operate when commanded
- Washer operates continuously or runs without command
- Intermittent operation or only works after wiggling connector
- Washer motor fuse blows repeatedly
- DTC B0111 stored in vehicle body control or camera system
What to check
- Scan for additional DTCs in body/camera and BCM modules
- Visually inspect actuator, connector and harness for corrosion, damage or water ingress
- Check fuse and relay for the washer circuit
- With key on, command the washer from the switch or scan tool while observing actuator behavior
- Measure voltage at actuator connector (supply and ground) while commanding
- Check resistance/continuity of actuator motor leads with connectors disconnected
Signal parameters
- Supply voltage (key ON, command active): ~0–14 V (should approach battery voltage when driven)
- Command signal: On/off or PWM from module — duty varies when active
- Motor coil resistance: typically low (a few ohms to tens of ohms) — shows continuity if good
- Return/ground continuity: near 0 ohms to chassis ground
- Current draw when running: expected hundreds of mA to a few amps (will rise if actuator is stalled)
Diagnostic algorithm
- Retrieve freeze-frame and related DTCs from all modules; note conditions when fault set
- Visually inspect actuator, nozzle and fluid lines for mechanical blockage or ice
- Inspect connector and wiring for corrosion, bent pins, damage or water intrusion
- Check washer circuit fuse and relay; replace if blown and retest
- Using a multimeter, measure supply voltage at actuator connector with key ON and during command; verify proper ground
- Measure motor coil resistance with connector disconnected to confirm continuity (compare left/right or known-good if available)
- Command actuator with scan tool while monitoring voltage/current; if no voltage from module, check upstream fuses/relays and wiring
- If wiring and power are good, bench-test actuator by applying regulated 12 V power briefly to confirm motor operation (observe polarity/connector orientation)
- If actuator fails bench test, replace actuator; if actuator works but module output is absent or abnormal, inspect wiring and consider BCM/control module driver fault
- After repair, clear DTCs and perform function test; verify no reoccurrence under the same conditions
Likely causes
- Corroded connector pins at camera washer actuator
- Broken or chafed wire shorting to chassis or power
- Actuator motor failed due to water ingress
- Blown fuse or defective relay feeding actuator circuit
- Intermittent module output or damaged driver stage in body control module
