Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid, wheel chocks.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any error codes related to the VSC system.
Clear the codes and see if they return upon restarting the vehicle.

3. Inspect and Replace Wheel Speed Sensors

Remove the wheel from the affected side(s) to access the wheel speed sensor.
Disconnect the sensor's electrical connector and remove the retaining bolt.
Inspect the sensor for damage or debris; clean or replace if necessary.
Reinstall the new or cleaned sensor, ensuring it is securely connected and torqued to specifications.

4. Check Brake Fluid Level

Locate the brake fluid reservoir and check the fluid level.
If low, top off with the appropriate brake fluid type as specified in the owner's manual.
Inspect for leaks around brake lines and connections.

5. Test and Replace VSC Control Module (if necessary)

Use a multimeter to check the voltage and ground connections at the VSC control module.
If the module is faulty, disconnect the battery, remove the module, and replace it with a new one.
Reconnect the battery and recheck the system for error messages.
