Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands if necessary.
Disconnect the battery to avoid electrical shocks.

2. Inspect Wheel Speed Sensors

Remove the wheel on the affected side using a socket set.
Clean the wheel speed sensor and its connector; ensure there is no debris.
Reconnect the sensor and wheel, then torque the lug nuts to manufacturer specifications.

3. Check ABS System

Inspect the ABS module for any visible leaks or damage.
Use a multimeter to test the ABS pump motor for continuity and functionality.
If faulty, replace the ABS module according to the manufacturer guidelines.

4. Inspect Brake Fluid

Locate the brake fluid reservoir and check the fluid level.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
If the fluid is contaminated, flush the brake system and replace with new fluid.

5. Verify Steering Angle Sensor

Access the steering angle sensor, typically located near the steering column.
Follow the manufacturer's calibration procedure to ensure proper operation.
Reconnect any connectors and ensure they are secure.
