Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Scan for Error Codes

Reconnect the battery terminal.
Use the OBD-II scanner to retrieve and note any error codes.
Clear the codes and restart the vehicle to see if the traction control light reappears.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the wheel speed sensor.
Inspect the sensor and wiring for any signs of damage or corrosion.
Clean the sensor with electrical cleaner if dirty.
Reinstall the wheel and lower the vehicle.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the fluid level is above the minimum mark; top off with brake fluid if necessary.
Inspect for any leaks in the brake lines or connections.

5. Inspect ABS Control Module

Locate the ABS control module, typically near the master cylinder.
Check for any loose connectors or damaged wiring.
If necessary, reconnect any loose wires and secure the connections.

6. Verify Tire Condition

Visually inspect all tires for uneven wear patterns and check the tire pressure using a tire pressure gauge.
Inflate or replace tires as needed to ensure all four tires are the same size and pressure.
