Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools including an OBD-II scanner, socket set, and a multimeter.

2. Scan and Clear Codes

Plug the OBD-II scanner into the port under the dashboard.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's instructions to scan for ABS-related error codes.
If codes are present, note them down for reference.
Use the scanner to clear the ABS codes and verify that the ABS light turns off.

3. Inspect ABS Components

Locate the ABS wheel speed sensors at each wheel.
Visually inspect each sensor for damage or dirt accumulation.
Clean any debris from the sensors using a soft cloth or compressed air.
Ensure connectors are securely attached to each sensor.

4. Check Fuses

Open the fuse box located under the dashboard or in the engine compartment.
Locate the ABS fuse (refer to the owner's manual for the exact fuse location).
Inspect the fuse for continuity using a multimeter. Replace if blown.

5. Verify Brake Fluid Levels

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the "MIN" and "MAX" markings.
If the fluid is low, top it off with the appropriate brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).
