Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, multimeter, cleaning supplies.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Clear ABS Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Navigate to the ABS section on the scanner.
Select the option to read and clear fault codes.
Confirm the action and wait for the scanner to complete the process.

Lift the vehicle and secure it with jack stands.
Remove the wheel to access the ABS sensor.
Disconnect the sensor wire harness.
Clean the sensor and mounting area with an appropriate cleaner.
Reconnect the sensor and wheel, then lower the vehicle.

4. Verify Brake Fluid Level
