Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Faulty Components

ABS Fuse and Relay:
- Locate the fuse box and check the ABS fuse for continuity; replace if blown.
- Test the ABS relay; replace if it fails the continuity test.
Brake Fluid Check:
- Remove the brake fluid reservoir cap and check fluid level; top off with manufacturer-recommended fluid if low.
ABS Wheel Speed Sensors:
- Remove the wheel (if necessary) to access speed sensors.
- Clean sensors with a suitable cleaner; inspect wiring for damage.
- Replace any damaged sensors.

3. Test ABS Module and Pump

Reconnect the battery and utilize the OBD-II scanner to clear any error codes.
Perform a functional test of the ABS pump by activating it through the scanner.
If the pump does not activate, consider replacing it.

4. Reassemble and Final Checks

Reinstall any components or wheels removed during the process.
Ensure all connections are secure and there are no visible leaks.
Reconnect the battery and start the vehicle.
