Solution

1. Preparation

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

2. Check and Clean Wheel Speed Sensors

Tools Required: Socket set, brake cleaner, rags
Remove the wheel to access the wheel speed sensor.
Disconnect the wheel speed sensor connector.
Clean the sensor and surrounding area with brake cleaner to remove debris.
Reinstall the sensor and connector securely.

3. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, turkey baster
Use a turkey baster to remove old brake fluid from the reservoir.
Refill the reservoir with fresh brake fluid as per the manufacturer's specifications.
Bleed the brake system if necessary to remove any air bubbles.

4. Test Traction Control Switch

Tools Required: Multimeter
Remove the switch from the dashboard panel.
Use a multimeter to check for continuity when the switch is toggled.
Replace the switch if it does not show continuity.

5. Verify ABS Control Module Functionality

Tools Required: OBD-II scanner
Reconnect the battery and power on the vehicle.
Scan the ABS control module for any error codes.
Clear any codes and check if the traction control light reactivates.

6. Tire Inspection and Replacement

Inspect all tires for proper inflation and tread depth.
Replace any tires that are worn or damaged to ensure optimal traction.
