Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool if it has been recently driven.

2. Check VSA Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the VSA fuse (refer to the vehicle’s manual for the exact fuse location).
Inspect the fuse for any signs of damage or breakage.
Replace with a new fuse of the same amperage if necessary.

3. Inspect Wheel Speed Sensors

Lift the vehicle and secure it on jack stands.
Remove the wheel to access the wheel speed sensors.
Visually inspect the sensors for damage, dirt, or disconnection.
Clean any debris and reconnect if necessary.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the minimum and maximum lines.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4).

5. Test VSA Switch

Locate the VSA switch on the dashboard.
Ensure the switch is in the "ON" position.
If the switch is faulty, replace it with a new one.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored codes.
Test drive the vehicle to see if the Check VSA light returns.
