Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensor area using a soft cloth.
Check wiring for signs of wear or damage; repair or replace as necessary.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect for leaks in brake lines or around the master cylinder.

4. Test Throttle Position Sensor

Reconnect the negative battery terminal.
Use a multimeter to test the throttle position sensor by measuring the voltage while the accelerator pedal is depressed.
If the readings are outside the specified range in the service manual, replace the throttle position sensor.

5. Clear Error Codes

After addressing any issues, use the OBD-II scanner to clear any stored error codes.
Start the engine and observe if the VSC light remains off.
