Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shocks.

2. Retrieve and Interpret Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and note any error codes related to the ABS system.
Research the codes to determine specific components that may require attention.

3. Inspect ABS Components

ABS Fuse Check:
- Locate the fuse box and identify the ABS fuse.
- Remove the fuse and inspect it for continuity; replace if blown.
Wheel Speed Sensors:
- Lift the vehicle and remove the wheel for access to the wheel speed sensors.
- Inspect the sensors for dirt or physical damage; clean or replace as necessary.
Wiring Inspection:
- Trace the wiring from the ABS module to the wheel speed sensors.
- Look for frayed wires or corrosion; repair or replace any damaged sections.

4. Brake Fluid Inspection

Locate the brake fluid reservoir.
Check the fluid level against the "Min" and "Max" lines; top off with the manufacturer's recommended brake fluid if low.
If the fluid is contaminated, perform a brake fluid flush.

5. Reconnect Battery and Test

Reconnect the battery.
Start the vehicle and check if the ABS light remains illuminated.
Perform a test drive to ensure that the braking system operates normally.
