Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the ABS system.

2. Scan for Error Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and note any ABS-related fault codes for further troubleshooting.

3. Inspect and Replace ABS Fuse

Locate the ABS fuse in the fuse box (refer to the owner's manual for exact location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.

4. Check and Clean Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate the wheel speed sensors at each wheel hub.
Clean the sensors and their mounting points with a soft cloth and electrical cleaner.
Ensure the sensors are properly connected and free from damage.

5. Test ABS Pump and Relay

Locate the ABS pump and relay (usually under the hood near the brake master cylinder).
Check for power supply to the pump using a multimeter.
If the pump does not activate, consider replacing the relay or pump based on further tests.

6. Reassemble and Test

Reconnect all components, ensuring all connections are secure.
Reconnect the negative battery terminal.
Start the engine and check if the ABS light is still illuminated.
