my Skoda Octavia NFL (2020-Present) ABS 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 prevent electrical issues.

2. Scan for Error Codes

• Use an OBD-II scanner to retrieve the ABS fault codes.
• Note the codes, as they will guide further diagnostic steps.

3. Inspect ABS Components

• ABS Sensor Wires:

  • Visually inspect all ABS sensor wiring for fraying or disconnection.
  • Repair or replace damaged wires as needed.

• ABS Module:

  • Check the ABS module for any signs of leaks or damage.
  • If the module is damaged, it will need replacement.

4. Test Wheel Speed Sensors

• Remove the wheel to access the wheel speed sensor.
• Use a multimeter to test the resistance of the sensor; it should match manufacturer specifications (typically between 800-2000 ohms).
• Replace any faulty wheel speed sensors.

5. Check Brake Fluid

• Inspect the brake fluid reservoir; ensure it is filled to the appropriate level with the correct type of brake fluid (usually DOT 4).
• Replace any contaminated brake fluid.

6. Reassemble and Reconnect

• Reassemble any components removed for inspection.
• Reconnect the battery and ensure all connections are secure.

7. Clear Error Codes

• Use the OBD-II scanner to clear the ABS fault codes.
• Verify that the ABS light is off after clearing codes.
