Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to ensure safety.

2. Retrieve Diagnostic Codes

Reconnect the OBD-II scanner to the vehicle.
Turn the ignition to the "ON" position without starting the engine.
Read and record any stored DTCs related to the traction control system.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel assembly.
Remove any debris or dirt from the sensor area using a soft brush.
Check the sensor connectors for corrosion or loose connections.
If a sensor is damaged, replace it with a new one.

4. Check ABS Module

Inspect the ABS module for signs of damage or leaks.
If DTCs indicate a fault in the ABS module, consider testing its functionality or replacing it.

5. Verify Wiring Harness

Examine the wiring harness related to the traction control system for frays or breaks.
Repair any damaged wires using appropriate electrical connectors.
Ensure all connectors are securely fastened.

6. Brake Fluid and Tire Inspection

Check the brake fluid level and top off with manufacturer-recommended fluid if necessary.
Inspect tires for proper inflation and even tread wear; replace if needed.
