Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Scan for Codes

Use the OBD-II scanner to retrieve any stored error codes related to the ABS and traction control.
Document the codes for future reference.

3. Inspect ABS Wheel Speed Sensors

Locate each wheel speed sensor on all four wheels.
Remove any debris or dirt around the sensors.
Check the wiring and connectors for damage; repair or replace as needed.

4. Check Brake Fluid and Lines

Inspect the brake fluid reservoir for adequate fluid level; refill if necessary with the correct fluid type.
Examine brake lines for leaks or corrosion; replace any damaged lines.

5. Inspect and Test ABS Control Module

Locate the ABS control module, usually found near the brake master cylinder.
Check for any visible damage or corrosion on the module and connectors.
If necessary, perform a bench test on the ABS module or replace it if faulty.

6. Reconnect Battery and Clear Codes

Reconnect the battery after all checks and repairs are complete.
Use the OBD-II scanner to clear any fault codes and check if the ABS light re-illuminates.
