Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to cool if it has been recently driven.

2. Inspect Wheel Speed Sensors

Sub-steps:
- Locate the wheel speed sensors at each wheel hub.
- Clean the sensor area to remove any debris or dirt.
- Disconnect the sensor connector and inspect for corrosion or damage.
- Test the resistance of each sensor using a multimeter (should be within manufacturer specifications).
- Reconnect any loose or damaged connectors.

3. Check Brake Fluid Level

Sub-steps:
- Locate the brake fluid reservoir under the hood.
- Ensure the fluid level is between the "MIN" and "MAX" lines.
- If low, top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
- Inspect for any leaks in the brake lines or around the master cylinder.

4. Inspect ABS Module

Sub-steps:
- Locate the ABS module, usually found near the brake master cylinder.
- Inspect the module for any signs of physical damage or corrosion.
- Check the electrical connectors for tightness and cleanliness.
- If necessary, replace the ABS module with a new or refurbished part.

5. Test Traction Control Switch

Sub-steps:
- Locate the traction control switch, usually found on the dashboard near the steering wheel.
- Disconnect the switch and test for continuity using a multimeter.
- Replace the switch if it fails the continuity test.
