Solution

1. Preparation

Gather tools: OBD-II scanner, torque wrench, multimeter, socket set.
Ensure the vehicle is parked on a level surface and the engine is off before starting work.

2. Address Fault Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve and document any error codes related to the traction control system.
Clear the codes and perform a test drive to see if the light returns. If it does, proceed to the next steps.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Locate each wheel speed sensor and visually inspect for dirt, damage, or loose connections.
Use a multimeter to test the sensor's resistance according to the service manual specifications.
If a sensor is faulty, replace it with a new one.

4. Check Brake Fluid and ABS Module

Open the hood and check the brake fluid reservoir. If low, top it off with the manufacturer-recommended brake fluid.
Inspect the ABS module connections for corrosion or loose wires. Repair any damaged wiring or connections.

5. Test Steering Angle Sensor

Use the OBD-II scanner to check the steering angle sensor's data while turning the steering wheel.
If the readings are erratic or out of range, recalibrate or replace the sensor as necessary.

6. Verify Tire Condition and Pressure

Inspect all tires for uneven wear, damage, or improper inflation.
Inflate tires to the manufacturer-recommended pressure as indicated on the driver's door jamb.
