Solution
1. Preparation
  • Gather tools and equipment: OBD-II scanner, torque wrench, tire pressure gauge, and any necessary replacement parts.
  • Ensure the vehicle is parked on a level surface and the parking brake is engaged.
2. Scan for Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Retrieve and document any fault codes related to the traction control system.
  • Clear any codes and monitor if they reappear after a test drive.
3. Inspect Wheel Speed Sensors
  • Locate each wheel speed sensor, typically near the brake calipers on each wheel hub.
  • Check for physical damage, dirt, or debris obstructing the sensor.
  • Clean any debris and reconnect any loose connectors.
4. Examine ABS Module
  • Access the ABS module, usually located near the brake master cylinder.
  • Inspect for damaged wiring or corrosion on connectors.
  • If necessary, replace the ABS module following manufacturer specifications.
5. Check Tire Pressure and Condition
  • Use a tire pressure gauge to measure the pressure in each tire.
  • Inflate or deflate tires to match the manufacturer’s recommended specifications.
  • Inspect tires for uneven wear or damage, and replace if necessary.
