Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace ABS Fuse

Locate the fuse box (refer to the owner's manual for specific location).
Remove the ABS fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace if blown.
Reinstall the new fuse and reconnect the battery.

3. Inspect and Clean Wheel Speed Sensors

Lift the vehicle safely using jack stands.
Remove the wheel to gain access to the wheel speed sensor.
Disconnect the sensor connector.
Clean the sensor and mounting area with a soft cloth or brush to remove debris.
Reconnect the sensor and reinstall the wheel.

4. Verify Brake Fluid Level

Open the hood and locate the brake master cylinder reservoir.
Check the brake fluid level; it should be between the minimum and maximum marks.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4, as specified in the owner's manual).

5. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the ABS module.
Look for fraying, corrosion, or disconnections.
If damaged, repair or replace the affected wiring or connectors.

6. Reset ABS Light

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored error codes, including the ABS light.
Perform a test drive to check if the light remains off.
