Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical shorts during repairs.

2. Inspect Wheel Speed Sensors

Remove the wheel corresponding to the affected wheel speed sensor.
Locate the wheel speed sensor and disconnect the electrical connector.
Check for physical damage or debris on the sensor.
Clean the sensor with brake cleaner and a soft cloth.
Reconnect the sensor and reassemble the wheel.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the appropriate brake fluid (DOT 4 recommended).
Recheck for leaks in brake lines and connections.

4. Inspect ABS Module

Locate the ABS module, usually near the brake master cylinder.
Check the connections for corrosion or looseness.
If necessary, use a multimeter to test the module for proper voltage and ground connection.
If a fault is detected, consider replacing the ABS module.

5. Test Steering Angle Sensor

Use an OBD-II scanner to access the steering angle sensor data.
Compare the readings with the actual steering position.
If discrepancies are found, recalibrate or replace the steering angle sensor as necessary.
