Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace ABS Fuse/Relay

Locate the fuse box and identify the ABS fuse using the diagram on the cover.
Remove the ABS fuse with a fuse puller and inspect for any breakage.
Replace with a new fuse of the same amperage if needed.
If the relay is faulty, remove it and replace with a new relay.

3. Brake Fluid Inspection

Open the master cylinder reservoir cap.
Check the brake fluid level; add manufacturer-recommended fluid if low.
Inspect the fluid for contamination; if dirty, proceed to flush the brake fluid system.

4. Wheel Speed Sensor Inspection

Safely lift the vehicle and secure it on jack stands.
Remove the wheel to access the ABS wheel speed sensor.
Disconnect the sensor's electrical connector and inspect the wiring for wear or corrosion.
Clean the sensor and its mounting surface; replace if damaged.

5. Test ABS Control Unit

Reconnect the battery and use the OBD-II scanner to clear any previous fault codes.
Start the vehicle and perform a brake test to observe the ABS operation.
If the ABS light returns, further diagnostics of the hydraulic control unit may be required, which could involve professional assistance.
