Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, and tire pressure gauge.
  • Ensure the vehicle is parked on a level surface and engage the parking brake.
  • Disconnect the negative terminal of the battery to prevent electrical shorts.
2. Scan for Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Turn the ignition to the "On" position without starting the engine.
  • Retrieve and note any DTCs related to the traction control system.
3. Inspect Wheel Speed Sensors
  • Locate the wheel speed sensors at each wheel hub.
  • Use a socket set to remove the sensor if necessary.
  • Clean any debris from the sensor and connector. Use a multimeter to check for continuity.
  • If a sensor is faulty, replace it with a new one, ensuring proper torque specifications are followed.
4. Check Brake Fluid Level
  • Open the hood and locate the brake fluid reservoir.
  • Inspect the fluid level; it should be between the "Min" and "Max" marks.
  • If low, top off with the manufacturer-recommended brake fluid.
5. Inspect ABS Module and Wiring
  • Locate the ABS module, usually near the brake master cylinder.
  • Visually inspect the module and wiring for signs of damage or corrosion.
  • If necessary, use a multimeter to test for voltage and ground at the module connector.
6. Test Traction Control Switch
  • Locate the traction control switch on the dashboard.
  • Use a multimeter to check for continuity when the switch is pressed.
  • Replace the switch if it fails the continuity test.
