Solution

1. Preparation

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

2. Retrieve and Analyze Diagnostic Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any error codes related to the traction control or ABS systems.
Clear the codes and see if they return after a test drive.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor mounting bolts using a socket set.
Gently pull the sensor out and clean it using an appropriate sensor cleaner.
Reinstall the sensor and torque the bolts to the manufacturer's specifications (typically around 7-9 lb-ft).

4. Check ABS Module and Wiring

Visually inspect the ABS module for any signs of damage or corrosion.
Use a multimeter to test the ABS module's connections for continuity.
Repair or replace any damaged wiring or connectors as necessary.

5. Brake Fluid Check and Replacement

Inspect the brake fluid reservoir; if low, top it off with the recommended DOT fluid.
If the fluid is contaminated, perform a brake fluid flush to ensure proper operation.

6. Test Drive

Reconnect the battery and start the vehicle.
Perform a test drive to monitor the traction control light and ensure it turns off when the system is functioning correctly.
