my Skoda Octavia NFL (2020-Present) traction control light is on, what does it mean?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the battery to avoid any electrical shorts during repair.

2. Inspect Wheel Speed Sensors

• Tools Required: Socket set, multimeter
• Remove the wheel covering the sensor (if necessary).
• Disconnect the wheel speed sensor connector.
• Use a multimeter to check for continuity and proper voltage output while spinning the wheel.
• Clean or replace the sensor if it shows signs of damage or fails the continuity test.

3. Check Brake Fluid Levels

• Tools Required: Brake fluid tester (if available)
• Open the hood and locate the brake fluid reservoir.
• Check the fluid level; if low, top off with the manufacturer-approved brake fluid.
• Inspect for any visible leaks in the brake lines or around the reservoir.

4. Inspect ABS Module

• Tools Required: Socket set, torque wrench
• Locate the ABS module (typically near the brake master cylinder).
• Check for loose connections or damaged wiring.
• Ensure the module is securely mounted; re-torque connections to manufacturer specifications.

5. Test Traction Control Switch

• Tools Required: Multimeter
• Locate the traction control switch inside the vehicle.
• Use a multimeter to test for proper function and continuity when the switch is engaged and disengaged.
• Replace the switch if it is faulty.

6. Reconnect Battery and Clear Codes

• Reconnect the battery.
• Use the OBD-II scanner to clear any fault codes.
• Start the vehicle and check if the traction control light remains off.
