Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to prevent electrical shorts.
Allow the vehicle to cool if it has been recently driven.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve ABS-related trouble codes.
Note down any codes for further analysis.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any debris or dirt around the sensor.
If damaged, replace the wheel speed sensor with a new one.

4. Check and Repair ABS Control Module

Locate the ABS control module, usually found near the master cylinder.
Inspect for any signs of corrosion or damaged wiring.
If necessary, replace the control module; follow manufacturer guidelines for programming.

5. Test ABS Pump Operation

Reconnect the battery and perform an activation test using the OBD-II scanner.
Listen for the ABS pump operation; if it does not activate, check electrical connections.
Replace the ABS pump if it is malfunctioning.

6. Brake Fluid Inspection

Check the brake fluid reservoir; ensure it is filled to the recommended level with the appropriate brake fluid type (DOT 3 or DOT 4).
If the fluid is contaminated, flush the brake system and refill with fresh brake fluid.
