Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the ignition is off.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Inspect and Clean Wheel Speed Sensors
  • Locate the wheel speed sensors at each wheel hub.
  • Remove any dirt or debris around the sensors and connectors.
  • Use a multimeter to check the resistance of each sensor; replace any that do not meet specifications.
3. Check ABS Module and Wiring
  • Visually inspect the ABS module and wiring for any signs of damage or corrosion.
  • If damage is found, replace the affected wiring or module.
  • Reconnect any loose connections ensuring a secure fit.
4. Brake Fluid Level Check
  • Locate the brake fluid reservoir and check the fluid level.
  • If low, refill with the appropriate type of brake fluid as specified in the owner's manual.
  • Inspect for any leaks in the brake lines or around the master cylinder.
5. Traction Control Switch Verification
  • Locate the traction control switch on the dashboard.
  • Test the switch for functionality by pressing it and observing if the traction control light toggles.
  • If the switch is faulty, replace it with a new one.
6. Reconnect Battery and Clear Codes
  • Reconnect the battery terminals after all repairs and checks are complete.
  • Use the OBD-II scanner to clear any stored error codes.
  • Start the vehicle and observe whether the traction control light remains off.
