B0108: LIDAR Washer Actuator C

What it means

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

How it works

LIDAR Washer Actuator C operates the washer function assigned to LIDAR channel C, helping remove dirt or other contamination from that sensor. B0108 flags a fault associated with actuator C; the code does not distinguish an actuator fault from low fluid, blocked plumbing, or an electrical problem.

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 B0108 and related washer codes, and review available status data for the LIDAR C actuator command.
2. Check washer-fluid level and inspect the LIDAR C nozzle and hoses for blockage, leaks, kinks, or disconnection.
3. Locate washer actuator C from service information and inspect its connector and wiring for corrosion, looseness, or damage.
4. Check the relevant fuse and verify actuator C's power and ground against the wiring diagram and manufacturer's specification.
5. Command actuator C with a compatible scan tool if supported, then check for operation and fluid delivery at the LIDAR C cleaning point.

Common fixes

• Refill the reservoir with the specified washer fluid.
• Clear a blockage or repair a leak, kink, or disconnection in the LIDAR C plumbing.
• Clean or secure the actuator C connector and repair damaged wiring.
• Replace a failed fuse after finding and correcting the cause.
• Replace LIDAR washer actuator C if circuit and plumbing checks pass but it does not operate.

Can I keep driving?

Driving is generally possible, but a dirty LIDAR C sensor may reduce or disable driver-assistance functions that rely on it. Keep the sensor clean and follow any vehicle warning about reduced sensor function.
