Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Wheel Speed Sensors

Sub-steps:
- Locate the wheel speed sensors at each wheel hub.
- Clean any dirt or debris from the sensor area to ensure a proper connection.
- Check the wiring harness for frays or breaks; repair as necessary.
- Use a multimeter to test the resistance of each sensor; replace any that are out of specification.
Tools Required: Multimeter, socket set.

3. Check Brake Fluid Level

Sub-steps:
- Locate the brake fluid reservoir under the hood.
- Inspect the fluid level; if low, top off with the manufacturer-recommended brake fluid.
- If the fluid is contaminated, flush the brake system and replace with fresh fluid.
Tools Required: Brake fluid, funnel.

4. Inspect ABS Module

Sub-steps:
- Locate the ABS module, usually found near the master cylinder.
- Check the module for any visible damage or leaks.
- Use the OBD-II scanner to clear any fault codes related to the ABS system and recheck for codes after a test drive.
Tools Required: OBD-II scanner.

5. Test Traction Control Switch

Sub-steps:
- Locate the traction control switch, typically found on the dashboard or center console.
- Use a multimeter to check for continuity when the switch is pressed.
- If the switch is faulty, replace it with a new one.
Tools Required: Multimeter, replacement switch.
