Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Gather necessary tools, including an OBD-II scanner, screwdriver set, and a multimeter.

2. Retrieve and Clear Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port, usually located under the dashboard near the steering column.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's instructions to read and note any ABS-related trouble codes.
Clear the codes using the scanner's "Clear Codes" function.

3. Inspect ABS System Components

Fuses: Locate the fuse box and check the ABS fuse. Replace with the same amperage fuse if blown.
Wheel Speed Sensors: Remove the wheel covers if necessary. Check each sensor for dirt accumulation and secure connections. Clean sensors with a soft cloth if dirty.
Wiring: Inspect the wiring harness leading to the ABS module. Look for frayed wires or loose connections.

4. Test and Reset ABS System

Reconnect Battery: If the ABS light persists, disconnect the negative battery terminal for at least 10 minutes to reset the system.
Reconnect Terminal: After the waiting period, reconnect the negative battery terminal securely.

5. Final Check

Start the vehicle and check the dashboard to see if the ABS light has turned off.
If the light remains on, further diagnostics may be required to identify underlying issues.
