Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to avoid any electrical issues while working.

2. Check and Replace Brake Fluid

Tools Required: Brake fluid tester, syringe, container for old fluid.
Sub-steps:
1. Remove the brake fluid reservoir cap.
2. Use a syringe to extract old brake fluid and dispose of it properly.
3. Fill the reservoir with the recommended type of brake fluid (DOT 3 or DOT 4 as specified by the manufacturer).
4. Reinstall the cap securely.

3. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter.
Sub-steps:
1. Lift the front or rear of the vehicle, depending on which sensors are being inspected, and secure it with jack stands.
2. Locate the wheel speed sensors on each wheel assembly.
3. Disconnect the electrical connector from the sensor.
4. Use a multimeter to test the sensor's resistance; replace if out of specification.
5. Reinstall the new sensor and reconnect the electrical connector.

4. Reset the VSC System

Tools Required: OBD-II scanner.
Sub-steps:
1. Reconnect the battery and turn on the ignition without starting the engine.
2. Use the OBD-II scanner to clear any diagnostic trouble codes (DTCs).
3. Start the engine and verify that the "Check VSC System" light is no longer illuminated.
