Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the ignition is turned off.
Disconnect the battery to prevent any electrical shorts while working on the ABS system.

2. Retrieve and Analyze Diagnostic Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Record any trouble codes displayed and interpret them based on the manufacturer’s service manual to identify specific issues with the ABS.

3. Inspect ABS Components

Check the ABS fuses in the fuse box; replace any blown fuses.
Inspect each wheel for ABS speed sensors; clean or replace any that are damaged.
Check wiring harnesses for frays. Repair or replace as necessary.

4. Brake Fluid and System Inspection

Check the brake fluid reservoir; if the fluid is low, fill it with the manufacturer's recommended brake fluid type.
Inspect brake lines for leaks or corrosion, fixing any issues found.

5. Reconnect and Test

Reconnect the battery.
Clear any stored trouble codes using the OBD-II scanner.
Start the engine and check if the ABS light and traction control warning are still illuminated.
Conduct a test drive to ensure the ABS system and traction control function correctly.
