Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, wheel chocks.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to ensure safety during electrical inspections.

2. Addressing Fault Codes

Reconnect the battery and turn on the ignition without starting the engine.
Use the OBD-II scanner to read the fault codes related to the traction control system.
Document any codes for reference.

3. Inspect Wheel Speed Sensors

Locate each wheel speed sensor near the brake assemblies.
Remove the wheel cover if necessary for access.
Disconnect the wheel speed sensor connector and inspect for corrosion or damage.
Clean the sensor and its mounting area; replace if damaged.

4. Check Brake System

Inspect the brake system components, including the ABS module, for any visible damage.
Use a multimeter to test the ABS module for proper operation according to manufacturer specifications.
Replace any faulty brake components as necessary.

5. Verify Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is activated.
Replace the switch if it does not function correctly.

6. Tire Inspection

Check each tire for proper inflation as per the manufacturer's recommended pressure.
Inspect for uneven wear or damage that may affect traction.
Replace tires if they are worn beyond safe limits.
