Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle's 12V 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 debris or dirt around the sensors using a soft brush or cloth.
  • Check the wiring harness connected to each sensor for any frays or disconnections.
3. Check ABS Module
  • Access the ABS module, typically located near the brake master cylinder.
  • Inspect the module for any signs of corrosion or damage.
  • Ensure all electrical connections are secure.
4. Brake Fluid Inspection
  • Open the brake fluid reservoir cap.
  • Check the fluid level; if low, top up with the recommended brake fluid type (usually DOT 3 or 4).
  • If the fluid is discolored or contaminated, consider a brake fluid flush.
5. Tire Inspection and Adjustment
  • Check each tire for proper inflation; adjust to the recommended PSI as indicated on the driver's side door jamb.
  • Inspect tires for uneven wear or damage; replace if necessary.
6. Reconnect Battery and Test
  • Reconnect the 12V battery.
  • Start the vehicle and check if the traction control light remains illuminated.
  • Take the vehicle for a test drive to verify proper operation of the traction control system.
