Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Diagnostic Scan

Tools Required: OBD-II scanner
Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Retrieve and note any error codes related to the traction control system.

3. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Locate the wheel speed sensors on each wheel hub.
Disconnect the sensor connectors and inspect for corrosion or damage.
Use a multimeter to test for proper voltage output when the wheel is turned.

4. Check Brake System

Tools Required: Brake fluid tester, socket set
Inspect the ABS module for any visible leaks or damage.
Check brake fluid levels and condition.
If necessary, bleed the brake system to ensure proper fluid flow.

5. Examine Traction Control Switch

Tools Required: Screwdriver set
Locate the traction control switch on the dashboard.
Remove the switch and check for any signs of wear or damage.
Test for continuity using a multimeter.

6. Assess Tire Condition

Inspect all tires for uneven wear, proper inflation, and matching sizes.
Replace any damaged or excessively worn tires.

7. Test Battery Voltage

Tools Required: Multimeter
Check the battery voltage; it should be around 12.6 volts or more.
Inspect battery terminals for corrosion and ensure tight connections.
