Solution

1. Preparation

Ensure the vehicle is on a level surface and the ignition is off.
Gather tools: OBD-II scanner, multimeter, socket set, and a brake fluid tester.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any error codes related to VSC or ABS.
Clear the codes and see if they reappear after a test drive.

3. Inspect Wheel Speed Sensors

Tools Needed: Socket set, multimeter.
Remove the wheel and tire to access the wheel speed sensor.
Inspect the sensor for damage or corrosion; clean or replace if necessary.
Use a multimeter to check the sensor’s resistance and functionality according to specifications.

4. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, add the recommended brake fluid type (DOT 3 or DOT 4).
If the fluid is contaminated, perform a brake fluid flush.

5. Inspect Throttle Position and Accelerator Pedal Sensors

Tools Needed: Multimeter.
Disconnect the connectors from the throttle position sensor and accelerator pedal position sensor.
Test the sensors for proper voltage output according to manufacturer specifications.
Replace any faulty sensors as necessary.
