Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.
Allow the vehicle to cool down if it has been running.

2. Inspect Wheel Speed Sensors

Sub-steps:
- Locate each wheel speed sensor; they are typically mounted near the brake assembly.
- Remove any dirt or debris around the sensors to ensure proper readings.
- Check wiring for frays or disconnections.
- Use a multimeter to test the sensor's resistance; replace if outside manufacturer specifications.

3. Check Brake Fluid Level

Sub-steps:
- Locate the brake fluid reservoir.
- Inspect fluid level; if low, top it up with the manufacturer-recommended brake fluid.
- If the fluid is contaminated, perform a brake fluid flush.

4. Examine ABS Module

Sub-steps:
- Locate the ABS module, usually found near the master cylinder.
- Inspect wiring connectors for corrosion or damage.
- Use a multimeter to check for proper voltage and continuity; replace the module if necessary.

5. Test Traction Control Switch

Sub-steps:
- Locate the traction control switch on the dashboard.
- Inspect for physical damage or debris.
- Use a multimeter to test the switch's functionality; replace if not operating correctly.
