OBD-II code B0117 indicates an electrical fault in the camera washer actuator circuit. The body control module has detected an issue, such as an open or short, preventing the washer actuator from properly spraying cleaning fluid onto the camera lens.
The actuator or dedicated pump for the camera washer has failed internally and can no longer operate when commanded.
The wiring between the control module and the actuator has an open circuit, short to ground, or short to voltage due to chafing or environmental damage.
The electrical connector at the actuator or control module has poor contact, corrosion, or pushed-back pins interrupting the circuit.
The fuse protecting the camera washer circuit has blown, cutting power to the actuator.
The module responsible for commanding the washer actuator has an internal driver failure. This is rare and should only be considered after all wiring and the actuator are proven good.
The definition is universal; the diagnostics are engine-specific. Open your vehicle for the codes documented for it:
Yes, the vehicle is safe to drive. This code only affects the ability to wash a specific camera lens, though visibility for camera-based safety systems may be compromised in dirty conditions.
No. The Powertrain Control Module (PCM) does not control the camera washers. This system is managed by a body control module or similar body electronics controller. Replacing any control module is rarely the correct fix for this code.
It can be. A blown fuse will cut power to the actuator and trigger this code. Checking the fuse is a quick and easy first step, but if it blows repeatedly, there is likely a short circuit in the wiring or the actuator itself.
You can manually clean the lens as a temporary workaround, but the underlying electrical fault should be diagnosed and repaired to restore proper automatic system function and clear the dashboard warning.
