Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Clean ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensor area using a cloth or brush.
If damaged, replace the wheel speed sensors.
Reconnect any disconnected sensors and ensure they are securely attached.

3. Check Wiring and Connectors

Inspect the wiring harness leading to the ABS control module and wheel speed sensors.
Look for frayed wires, corrosion, or loose connectors.
Repair or replace any damaged wiring or connectors as needed.

4. Inspect ABS Control Module

Locate the ABS control module, typically mounted near the brake master cylinder.
Check for any visible signs of damage or leaks.
If necessary, test the module's functionality using a multimeter or consult with a professional for further diagnostics.
Replace the ABS control module if found to be faulty.

5. Refill and Bleed Brake Fluid (if necessary)

Check the brake fluid reservoir and ensure it is filled to the recommended level with the correct type of brake fluid (typically DOT 3 or DOT 4).
If any fluid has been lost during inspection, bleed the brake system to remove any air bubbles.
Reconnect the negative battery terminal once all repairs are completed.
