Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Allow the vehicle to cool if recently driven.

2. Inspect and Clean ABS Sensors

Locate the ABS sensors at each wheel hub.
Remove any dirt, debris, or corrosion on the sensor and mounting area using a soft brush and cleaning solution.
Reconnect any disconnected connectors securely.

3. Check and Replace Brake Fluid

Remove the brake fluid reservoir cap.
Inspect the fluid level; if low, fill with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated, perform a brake fluid flush.
Replace the reservoir cap securely.

4. Inspect and Repair Wiring

Visually inspect the wiring harness leading to the ABS module and sensors.
Look for frayed wires, loose connections, or signs of corrosion.
Repair or replace any damaged wiring as necessary.

5. Test and Replace ABS Control Module (if needed)

If error codes indicate a malfunctioning ABS control module, remove the module by disconnecting the wiring harness and unscrewing it from its mount.
Install a new or refurbished ABS control module, ensuring all connections are tight and secure.
