Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat, stable surface with the ignition off.
Disconnect the battery to ensure safety while working on the electrical components.

2. Retrieve Diagnostic Codes

Use an OBD-II scanner to connect to the vehicle's diagnostic port.
Record any DTCs related to the ABS system for further analysis.

3. Inspect ABS System Components

ABS Fuse Check:
- Locate the fuse box and find the ABS fuse.
- Remove the fuse and visually inspect it; replace if blown.
Wheel Speed Sensors:
- Remove the wheel on which you suspect the ABS issue.
- Locate the wheel speed sensor and inspect it for dirt or damage.
- Clean the sensor with a soft cloth or replace it if faulty.

4. Check Brake Fluid and System

Open the master cylinder reservoir and check the brake fluid level.
If low, top off with the manufacturer-recommended brake fluid.
Inspect for any leaks around the brake lines and ABS module.

5. Inspect Wiring and Connectors

Follow the wiring harness from the ABS module to the wheel speed sensors.
Look for any frayed wires, corrosion, or loose connections.
Repair or replace damaged wiring or connectors as necessary.

6. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and check if the ABS light has turned off.
Perform a test drive to ensure ABS functionality.
