Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel corresponding to the faulty speed sensor.
Disconnect the wheel speed sensor wiring harness.
Use a multimeter to test the sensor's resistance; replace if out of specification.
Install the new wheel speed sensor, reconnect the wiring harness, and reattach the wheel.

3. Check and Replace ABS Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box (usually under the dashboard or engine compartment).
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity; replace if blown with the same amperage rating.

4. Brake Fluid Check and Replacement

Tools Required: Brake fluid, funnel
Inspect the brake fluid level; top off if low with the manufacturer-recommended fluid (usually DOT 3 or DOT 4).
If the fluid is contaminated, perform a brake fluid flush and replace with new fluid.

5. Reconnect Battery and Reset ABS Light

Reconnect the battery terminals.
Use the OBD-II scanner to clear any stored ABS codes.
Test drive the vehicle to confirm ABS light is off and system is operational.
