Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the vehicle battery to avoid any electrical issues.

2. Inspect and Replace ABS Fuse

Locate the fuse box (refer to the vehicle’s manual for location).
Remove the cover and identify the ABS fuse.
Use a multimeter to check for continuity in the fuse.
Replace the fuse if it is blown (use the same amperage rating).
Reassemble the fuse box cover.

3. Check Brake Fluid

Locate the brake fluid reservoir.
Inspect the fluid level; it should be between the MIN and MAX marks.
If low, add the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect the condition of the brake fluid; if it appears dark or contaminated, perform a brake fluid flush.

4. Inspect Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the ABS wheel speed sensor.
Check for any physical damage or disconnection of the sensor.
Clean any debris from around the sensor and the reluctor ring.
Reconnect any loose connectors and ensure they are secure.

5. Reconnect Battery and Test

Reconnect the battery terminal securely.
Start the vehicle and check if the ABS light is still illuminated.
Test drive the vehicle to confirm normal braking function and monitor for any warning lights.
