Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Sub-steps:
- Locate the wheel speed sensors at each wheel hub.
- Remove the sensor mounting bolts using a socket set.
- Clean any dirt or debris from the sensor and the mounting area.
- Reinstall the sensors and ensure they are securely fastened.

3. Check Wiring and Connectors

Sub-steps:
- Trace the wiring from each wheel speed sensor back to the ABS module.
- Look for frayed wires, corrosion, or loose connections; repair or replace as necessary.
- Use a multimeter to check for continuity in the wiring between the sensors and the ABS module.

4. Inspect Brake System Components

Sub-steps:
- Remove the wheel to access the brake assembly.
- Inspect the ABS control module for any signs of fluid leakage or damage.
- Check the brake lines for any damage or blockage that may affect braking performance.

5. Reconnect Battery and Clear Codes

Sub-steps:
- Reconnect the negative battery terminal securely.
- Use an OBD-II scanner to clear the fault codes from the system.
- Start the vehicle and check for the illumination of warning lights.
