Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery cable to ensure safety.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from the sensor.
Use a multimeter to test for continuity; replace the sensor if faulty.
Reconnect the sensor and ensure it is securely fastened.

3. Check and Refill Brake Fluid

Open the hood and locate the brake master cylinder.
Check the brake fluid level; if low, add the manufacturer-recommended brake fluid.
Inspect for any leaks in the brake lines or around the master cylinder.

4. Inspect Fuses

Locate the fuse box (usually under the dashboard or engine compartment).
Check the fuses associated with the VSC and ABS systems.
Replace any blown fuses with the same amperage rating.

5. Reset the VSC Light

Reconnect the negative battery cable after completing the repairs.
Start the engine and allow it to idle for a few minutes.
Use an OBD-II scanner to clear any stored trouble codes from the system.
