Solution

1. Preparation

Gather all necessary tools and parts. Ensure the vehicle is parked on a level surface and the ignition is off.
Tools required: OBD-II scanner, multimeter, socket set, tire pressure gauge, brake fluid.

2. Scan and Clear Codes

Use the OBD-II scanner to retrieve any diagnostic trouble codes (DTCs) related to the traction control system.
Document error codes for reference and clear them to see if they return after repairs.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel.
Disconnect the electrical connectors and remove the sensors using a socket set.
Clean any debris or dirt from the sensor and the mounting area using a brake cleaner.
Reinstall the sensors and connectors, ensuring they are secure.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, add the recommended brake fluid type as specified in the owner's manual.
Check for any leaks in the brake lines or around the brake calipers.

5. Inspect ABS Control Module

Locate the ABS control module, usually found near the brake master cylinder.
Check for any visible damage, corrosion, or loose connections.
If necessary, test the module with a multimeter for proper voltage and continuity.

6. Reconnect Battery and Test Drive

Reconnect the vehicle battery if it was disconnected during inspection.
Test drive the vehicle on various surfaces to ensure the traction control system is functioning properly.
