Use an OBD-II scanner to retrieve any DTCs (Diagnostic Trouble Codes).
Clear any codes after taking note of them.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris around the sensors and connectors.
Test the sensors with a multimeter to ensure they are functioning correctly (check resistance values based on manufacturer specifications).

4. Check Traction Control Switch

Inspect the traction control switch for physical damage or malfunction.
If necessary, remove the switch from the dashboard and test for continuity using a multimeter.
Replace the switch if it does not meet specifications.

5. Brake System Check

Inspect the brake components, including the brake pads, rotors, and ABS module.
If any brake components are worn or damaged, replace them as needed.
Ensure the ABS module is functioning properly.
