Solution

1. Preparation

Gather tools and materials needed for repairs.
Disconnect the battery to ensure safety while working on electrical components.

2. Address Engine Light

Sub-steps:
1. After scanning for codes, note any stored trouble codes.
2. Research the specific error codes and determine necessary repairs (e.g., replace O2 sensor, catalytic converter, etc.).
3. Perform the required repairs based on identified codes.
4. Clear the codes using the OBD-II scanner.

3. Brake System Warning Light

Sub-steps:
1. Inspect the brake fluid level in the reservoir; refill if necessary with DOT 3 or DOT 4 brake fluid.
2. Check for leaks in the brake lines and around calipers; replace any damaged components.
3. Test the brake system; if warning persists, inspect the brake pads and sensors.

4. Battery and Charging System

Sub-steps:
1. Use a multimeter to check the battery voltage (should be around 12.6V when off and 13.7-14.7V while running).
2. Clean battery terminals and check for tight connections.
3. Replace the battery if it fails to hold a charge or test below specifications.

5. VSA Light

Sub-steps:
1. Reset the VSA system by pressing the VSA button on the dashboard.
2. If the light remains on, use the OBD-II scanner to diagnose related codes.
3. Inspect wheel sensors and wiring for damage; replace or repair as necessary.
