Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shorts while working on the vehicle.

2. Scan for Error Codes

Use an OBD-II scanner to connect to the vehicle’s diagnostic port.
Record any trouble codes related to the traction control system.
Clear the codes and monitor if they return after a test drive.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris obstructing the sensors.
Check the wiring for any signs of damage or corrosion.
If a sensor is faulty, replace it with a new one.

4. Check ABS Module

Inspect the ABS module for any visible damage or loose connections.
Use a multimeter to test the power and ground circuits at the ABS module.
Repair or replace any faulty wiring or connectors.

5. Brake Fluid Level Check

Locate the brake fluid reservoir under the hood.
Ensure the brake fluid is at the proper level; refill with the manufacturer-recommended brake fluid if necessary.
Inspect for any leaks in the brake system.

6. Tire Inspection

Check the tire tread depth using a tread depth gauge.
Look for signs of uneven wear or damage.
Replace any worn or damaged tires to ensure proper traction.
