my Skoda Octavia NFL (2020-Present) traction control light came on what to do

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

• Tools Required: Socket set, cleaning brush, electrical contact cleaner.
• Locate the wheel speed sensors at each wheel hub.
• Remove the sensor bolts using the socket set.
• Carefully pull the sensor out and inspect for dirt or damage.
• Clean the sensor and mounting area with a brush and electrical contact cleaner.
• Reinstall the sensor and torque to manufacturer specifications.

3. Check ABS Module and Wiring

• Tools Required: Multimeter, socket set.
• Locate the ABS module, usually found near the brake master cylinder.
• Inspect all wiring harnesses connected to the ABS module for frays or corrosion.
• Use a multimeter to test the continuity of the wires leading to the wheel speed sensors.
• Repair or replace damaged wires as necessary.

4. Refill Brake Fluid if Low

• Tools Required: Brake fluid, funnel.
• Check the brake fluid reservoir for proper fluid level.
• If low, top off with the recommended brake fluid type (check owner's manual).
• Ensure the cap is securely replaced.

5. Reconnect Battery and Clear Codes

• Reconnect the battery terminals and ensure they are tight.
• Use the OBD-II scanner to clear any existing trouble codes.
• Start the vehicle and check if the traction control light remains illuminated.
