Solution

1. Preparation

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

2. Address Fault Codes

Sub-step 1: Use the OBD-II scanner to clear any existing fault codes.
Sub-step 2: Monitor for the reappearance of the traction control light after clearing the codes, indicating persistent issues.

3. Repair Wheel Speed Sensors

Sub-step 1: Remove the wheel corresponding to the faulty wheel speed sensor.
Sub-step 2: Disconnect the wiring harness from the wheel speed sensor.
Sub-step 3: Remove the sensor from its mount, typically held by a bolt; replace it if damaged.
Sub-step 4: Install the new sensor and reconnect the wiring harness.
Sub-step 5: Reinstall the wheel and torque the lug nuts to the manufacturer specifications.

4. Check Brake Fluid Level

Sub-step 1: Locate the brake fluid reservoir under the hood.
Sub-step 2: Inspect the fluid level; if low, fill it to the recommended level with the appropriate brake fluid type (DOT 4 is typical).
Sub-step 3: Check for any signs of leaks in the brake lines.

5. Inspect ABS Module

Sub-step 1: Access the ABS module, typically located near the master cylinder.
Sub-step 2: Inspect the wiring and connectors for corrosion or damage.
Sub-step 3: If necessary, replace the ABS module with a new unit and ensure proper connection.

6. Verify Stability Control Switch

Sub-step 1: Locate the stability control switch on the dashboard.
Sub-step 2: Test the switch for proper operation; replace if it is faulty.
