Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Retrieve Trouble Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Record any trouble codes related to the ABS system for further diagnosis.

3. Inspect and Replace ABS Fuse

Locate the fuse box; refer to the owner's manual for the ABS fuse location.
Remove the fuse and check for continuity using a multimeter.
If the fuse is blown, replace it with a new one of the same amperage.

4. Inspect ABS Wheel Speed Sensors

Raise the vehicle securely on jack stands.
Remove the wheels to access the wheel speed sensors.
Inspect each sensor for damage, dirt, or disconnection.
Clean or replace any damaged sensors as needed.

5. Check ABS Module and Wiring

Locate the ABS module, typically found near the brake master cylinder.
Visually inspect the module and its wiring for signs of corrosion or loose connections.
Reconnect any loose wires and clean connections with electrical contact cleaner.

6. Verify Brake Fluid Level

Check the brake fluid reservoir located near the driver's side of the engine bay.
If the fluid is low, add the manufacturer-recommended brake fluid type (DOT 3 or DOT 4).
If the fluid is contaminated or dark, perform a brake fluid flush.

7. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light remains illuminated.
Perform a test drive to ensure normal braking function and verify the ABS system operates correctly.
