what does it mean if my Skoda Octavia’s ABS light is on?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and securely elevated with jack stands if needed.

2. Clear Fault Codes

• Connect the OBD-II scanner to the vehicle's diagnostic port.
• Select the ABS system and clear any fault codes stored in the system.
• Disconnect the scanner after clearing codes.

3. Inspect and Repair Wiring

• Visually inspect the ABS wiring harness for frays, cuts, or corrosion.
• If damage is found, repair or replace the affected wiring.
• Ensure all connectors are clean and secure.

4. Replace Faulty Wheel Speed Sensors

• If wheel speed sensors are found to be faulty, remove the wheel and brake assembly to access the sensors.
• Unscrew the sensor from its mounting point and disconnect the wiring harness.
• Install the new sensor and secure it in place, ensuring proper alignment.
• Repeat for all affected sensors.

5. Check Brake Fluid and System

• Remove the brake fluid reservoir cap and check fluid level; top off with manufacturer-recommended brake fluid if low.
• Inspect for any leaks in the brake system; repair any leaks found.
• Reinstall the brake fluid reservoir cap securely.

6. Test Drive

• Start the vehicle and perform a test drive to ensure the ABS light remains off and the system functions correctly.
