Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set, screwdrivers), brake cleaner, and a torque wrench.
Ensure the vehicle is parked on a level surface and the ignition is off. Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace ABS Fuse

Locate the fuse box under the dashboard or hood.
Remove the cover and locate the ABS fuse using the diagram on the cover.
Use a multimeter to test the fuse continuity; replace if blown.
Reconnect the fuse box cover.

3. Inspect Wheel Speed Sensors

Raise the vehicle and support it on jack stands.
Remove the wheel to access the wheel speed sensor.
Visually inspect the sensor and wiring for any damage, debris, or disconnections.
Clean the sensor using brake cleaner if dirty.
Reinstall the wheel and lower the vehicle.

4. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, fill with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Check for any leaks in the brake lines or around the master cylinder.

5. Test the ABS Module

Reconnect the battery and use the OBD-II scanner to clear any fault codes.
Test drive the vehicle to check if the ABS warning light reappears.
If the light persists, the ABS module may require replacement.
