B0107: LIDAR Washer Actuator B

What it means

This code identifies a fault associated with LIDAR Washer Actuator B. The code alone does not specify the failure mode.

How it works

LIDAR Washer Actuator B operates the washer function assigned to LIDAR channel B, which helps clear contamination from that sensor. B0107 identifies a fault associated with actuator B, though low washer fluid or a blocked hose can also prevent cleaning.

Common causes

Most likely first.

1. Faulty washer actuator
2. Damaged wiring
3. Loose or corroded connector
4. Low washer fluid or blocked plumbing

Symptoms

• LIDAR sensor cleaning warning
• Reduced driver assistance function
• Warning message

How to diagnose it

1. Scan the driver-assistance or body module for B0107 and related washer faults, and check available status data for the LIDAR B actuator command.
2. Verify washer-fluid level, then inspect the LIDAR B nozzle and its hoses for blockage, leaks, kinks, or disconnection.
3. Find washer actuator B using service information and inspect its connector and wiring for corrosion, looseness, or physical damage.
4. Check the applicable fuse and verify actuator B power and ground against the wiring diagram and manufacturer's specification.
5. If supported, command actuator B with a scan tool and check for actuator operation and fluid delivery to LIDAR B.

Common fixes

• Refill the reservoir with the specified washer fluid.
• Clear a blockage or repair a leaking, kinked, or disconnected LIDAR B hose.
• Clean or secure actuator B's connector and repair damaged wiring.
• Replace a failed fuse after checking the circuit for a short or overload.
• Replace LIDAR washer actuator B if it fails testing with sound wiring and plumbing.

Can I keep driving?

You may be able to drive, but contamination on LIDAR B can limit driver-assistance functions that use that sensor. Keep it clean and heed any reduced-sensor-function warnings.
