Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Clean ABS Sensors

Remove the wheel where the ABS sensor is located.
Detach the ABS sensor from its mounting bracket.
Clean the sensor and its mounting area with brake cleaner to remove debris.
Reinstall the ABS sensor and wheel, ensuring it is securely fastened.

3. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if it's low, add brake fluid that meets the manufacturer’s specifications (usually DOT 3 or DOT 4).
If the fluid is dark or contaminated, perform a brake fluid flush and replace with fresh fluid.

4. Test ABS Pump and Module

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use a multimeter to test the ABS pump and module for continuity and proper voltage.
Replace any components that are not functioning correctly based on test results.

5. Clear Error Codes

After all checks and repairs, use the OBD-II scanner to clear any stored ABS fault codes.
Test drive the vehicle to ensure that the ABS light does not reappear.
