Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Retrieve and note any error codes related to the VSA system.

3. Inspect Brake Fluid

Locate the brake fluid reservoir.
Check the fluid level; if low, top off with the manufacturer's recommended brake fluid.
If the fluid is contaminated, perform a brake fluid flush.

4. Check Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate each wheel speed sensor on the wheel hub assembly.
Inspect for any damage or disconnection of the wiring harness.
Clean the sensor and connector if dirty.

5. Examine ABS Module

Locate the ABS module, typically near the master cylinder.
Inspect for any visible wiring issues or corrosion.
Use a multimeter to test the module for proper voltage and ground.

6. Reset VSA System

After addressing any identified issues, use the OBD-II scanner to clear the error codes.
Start the vehicle and observe if the Check VSA light remains off.
