Solution

1. Preparation

Gather tools and parts required for the repair.
Safety gear: gloves and goggles.
Ensure the vehicle is parked on a level surface with the parking brake engaged.

2. Diagnostic Code Resolution

If error codes indicate specific faults (e.g., faulty sensor), note them for targeted repairs.
Clear the codes using the OBD-II scanner and test drive to check if the ABS light reappears.

3. Inspect and Clean Wheel Speed Sensors

Remove the wheel corresponding to the wheel speed sensor showing a fault.
Use a socket set to detach the sensor from its mount.
Clean the sensor and the area around it with a brake cleaner.
Reinstall the sensor and secure it properly.

4. Check ABS Control Module

Disconnect the battery to prevent any electrical shorts.
Remove the ABS control module using a socket set, taking care not to damage any wiring.
Inspect the module for corrosion or physical damage.
If necessary, replace the ABS control module with a new or refurbished one.

5. Test Brake Fluid and System Integrity

Check the brake fluid level; top up with the correct type if low.
Inspect brake lines for any signs of leaks or damage.
Replace any damaged components.

6. Reassemble and Test

Reconnect the battery and ensure all components are securely in place.
Start the vehicle and check if the ABS light turns off.
Test drive the vehicle to verify proper ABS function and ensure no warning lights remain.
