Solution

1. Preparation

Gather tools and parts needed.
Disconnect the negative battery terminal to ensure safety.
Secure the vehicle on a level surface and engage the parking brake.

2. Inspect and Clean ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any dirt or debris using a soft cloth or brush.
Check the wiring and connectors for any signs of damage.
Reattach any loose connectors and ensure a secure connection.

3. Check and Replace Fuse/Relay

Locate the fuse box and identify the ABS fuse.
Use a multimeter to check for continuity; replace the fuse if it is blown.
Test the ABS relay for functionality and replace if necessary.

4. Inspect Brake Fluid Level and Condition

Check the brake fluid reservoir; if low, top it off with the recommended brake fluid type (usually DOT 3 or DOT 4).
Inspect for signs of contamination or moisture in the brake fluid; if present, flush the brake system.

5. Clear Error Codes and Test Drive

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored error codes.
Test drive the vehicle to ensure the ABS light does not re-illuminate.
