Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shorts.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any fault codes related to the ABS system.
Clear the codes and see if they return after a test drive.

3. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel assembly.
Remove the sensor connector and visually inspect for damage or dirt.
Clean the sensor with brake cleaner if dirty, and reconnect.
If damaged, replace the sensor with a new one.

4. Check ABS Control Module

Locate the ABS control module, usually found near the brake master cylinder.
Inspect the module for physical damage or corrosion.
Use a multimeter to test the power and ground connections to the module.
If the module is faulty, replace it with an OEM part.

5. Verify Brake Fluid Levels

Open the hood and locate the brake fluid reservoir.
Check the fluid level; top off with the manufacturer-recommended brake fluid if low.
Inspect for leaks in the brake lines and fittings.

6. Reassemble and Test Drive

Reconnect the battery.
Start the vehicle and check that the ABS light is off.
Conduct a test drive to ensure the ABS system is functioning correctly.
