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

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface.
• Gather tools including a multimeter, socket set, and OBD-II scanner.
• Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace ABS Fuse

• Locate the fuse box and identify the ABS fuse.
• Remove the fuse using a fuse puller or pliers.
• Inspect the fuse for continuity; replace if blown.
• Reinstall the fuse and reconnect the battery.

3. Check Brake Fluid Level

• Open the hood and locate the brake master cylinder.
• Inspect the brake fluid level, ensuring it is within the recommended range.
• If low, top off the brake fluid with the appropriate type specified in the owner's manual.

4. Inspect ABS Wheel Speed Sensors

• Raise the vehicle using jack stands for safety.
• Remove the wheel to access the ABS sensor.
• Check for physical damage or dirt on the sensor.
• If damaged, replace the ABS wheel speed sensor with a new one.

5. Test ABS Wheel Speed Sensors

• Reconnect the battery and use a multimeter to test each sensor's resistance.
• The typical resistance should be between 800-2500 ohms; replace sensors that fall outside this range.

6. Inspect Wiring and Connectors

• Visually inspect the wiring harness connected to the ABS module and sensors for any signs of wear or damage.
• Repair or replace damaged wiring as necessary.
• Ensure all connectors are clean and securely fastened.
