what does it mean when the ABS light comes on in my Skoda Octavia?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.
• Disconnect the vehicle's battery to prevent electrical shorts.

2. Inspect and Replace ABS Fuse

• Locate the fuse box and determine the ABS fuse location using the owner's manual.
• Remove the ABS fuse using a fuse puller or pliers.
• Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Check and Replace Wheel Speed Sensors

• Raise the vehicle securely on jack stands.
• Locate each wheel speed sensor at the wheel hub.
• Disconnect the sensor connector and inspect for damage.
• Use a multimeter to measure resistance; it should typically be between 1,000 and 2,500 ohms.
• If the sensor is faulty, remove the retaining bolts and replace the sensor with a new one, ensuring proper alignment.

4. Inspect ABS Module and Wiring

• Visually inspect the wiring harness connected to the ABS module for fraying or damage.
• If any damaged wires are found, repair or replace them as necessary.
• Reconnect all connectors securely and clean any corrosion.

5. Reconnect Battery and Clear Codes

• Reconnect the vehicle's battery.
• Use the OBD-II scanner to clear any ABS-related codes from the system.
• Start the vehicle and observe if the ABS light remains illuminated.
