The B0119 code indicates a fault in the rear‑camera washer actuator circuit, meaning the system that sprays water on the rear‑view camera is not functioning as commanded.
The actuator motor or its internal valve can fail mechanically or electrically, preventing water flow even when the control signal is present.
Damaged, corroded, or loose wiring, connectors, or insulation can interrupt power or ground to the actuator.
The fuse or relay that supplies power to the actuator circuit may be open or intermittently contacting.
In rare cases, the BCM may not provide the correct command to the actuator circuit, but this is less common than actuator or wiring issues.
The definition is universal; the diagnostics are engine-specific. Open your vehicle for the codes documented for it:
No. The code relates to the rear‑camera washer actuator, which is controlled by the body control module, not the engine control module. Replacing the PCM will not resolve the issue.
It is not essential for vehicle operation, but the washer helps keep the camera lens clear for driver‑assistance systems that rely on the rear‑view camera.
When you command the washer (often via the rear‑defrost or camera‑wash button), you should hear a click and see water spray. No sound or spray indicates a failed actuator or a circuit problem.
Yes. Intermittent connections can trigger the code sporadically, so checking and securing all related connectors is a key diagnostic step.
