Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using jack stands to access the wheel wells.
2. Locate the wheel speed sensors on each wheel hub.
3. Clean the sensors and their connectors to remove any dirt or debris.
4. Check the sensor wiring for frays or breaks.
5. Reconnect any loose connections securely.

3. Examine ABS Module

Sub-steps:
1. Locate the ABS module, typically found near the brake master cylinder.
2. Inspect the wiring harness for damage or corrosion.
3. If error codes indicate a malfunction, consider replacing the ABS module.
4. Reconnect all connections and ensure they are secure.

4. Check Brake Fluid Level

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; it should be between the "MIN" and "MAX" lines.
3. If low, top off with the recommended brake fluid type as specified in the owner’s manual.
4. Inspect for leaks in the brake lines and around the master cylinder.

5. Test Traction Control Switch

Sub-steps:
1. Locate the traction control switch, usually on the dashboard.
