Solution
1. Preparation
  • Gather tools and parts needed.
  • Ensure the vehicle is parked on a level surface with the ignition turned off.
  • Disconnect the battery to prevent electrical issues.
2. Inspect Wheel Speed Sensors
  • Locate the wheel speed sensors at each wheel hub.
  • Remove any dirt or debris from the sensor area.
  • Disconnect the wiring harness from the wheel speed sensor.
  • Use a multimeter to check the resistance of each sensor; it should be within specifications (typically 1,000-2,500 ohms).
  • If a sensor is faulty, replace it.
3. Check ABS Module
  • Locate the ABS module, usually found near the brake master cylinder.
  • Inspect for any visible damage, corrosion, or loose connections.
  • If necessary, use a scanner to run a diagnostic check on the ABS system.
  • Replace the ABS module if it fails testing.
4. Inspect Brake Fluid and System
  • Check the brake fluid reservoir; ensure the fluid is at the recommended level.
  • Look for leaks in brake lines, hoses, and connections.
  • If the fluid is low, top it up with the appropriate brake fluid type (usually DOT 4).
  • Repair any leaks found in the brake system.
5. Reconnect Battery and Clear Codes
  • Reconnect the battery terminals securely.
  • Use the OBD-II scanner to clear any stored codes from the traction control system.
  • Start the vehicle and check if the traction control light remains off.
