Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, brake fluid, and cleaning supplies.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Scan for Diagnostic Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Read and document any ABS-related trouble codes that appear.

3. Inspect Wheel Speed Sensors

Locate the ABS wheel speed sensors on each wheel hub.
Disconnect the electrical connectors and inspect for dirt or damage.
Clean the sensors using an appropriate cleaner and reconnect them.
If damaged, replace the sensors with new ones.

4. Check Brake Fluid and System Integrity

Open the hood and locate the brake fluid reservoir.
Ensure brake fluid is at the recommended level; top up if necessary.
Inspect for leaks around the master cylinder, brake lines, and calipers.
Replace any damaged components and bleed the brake system to remove air.

5. Examine ABS Module and Wiring

Locate the ABS control module, usually near the master cylinder.
Check for any loose or corroded connections.
Use a multimeter to test the wiring for continuity and proper voltage.
Repair or replace any faulty wiring or connectors.

6. Test Drive and Monitor

Start the vehicle and perform a test drive to confirm that the ABS light remains off.
Monitor braking performance and listen for any unusual noises.
