Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Brake Fluid Inspection

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Check the fluid level; if low, top off with manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
- Inspect the fluid for contamination or discoloration.

3. Inspect Wheel Speed Sensors

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheels to access the wheel speed sensors.
- Inspect each sensor for debris, damage, or loose connections.
- Use a multimeter to test the resistance of each sensor (specification: typically between 800 to 1600 ohms).

4. Examine VSA Control Unit

Sub-steps:
- Locate the VSA control unit (usually near the ABS module).
- Inspect the wiring harness for frayed wires or corrosion at the connectors.
- Clean any corrosion using electrical contact cleaner and reconnect securely.

5. Reconnect Battery and Reset Light

Sub-steps:
- Reconnect the negative battery terminal.
- Start the vehicle and use the OBD-II scanner to clear any error codes.
- Test drive the vehicle to ensure the Check VSA light does not reappear.
