Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Ensure the vehicle is parked on a level surface.

2. Addressing the Check Engine Light

Connect the OBD-II scanner and note any error codes.
Research the identified codes to determine necessary repairs.
Clear the codes with the scanner and see if they reappear after a test drive.

3. Inspecting the Brake System

Visually inspect brake fluid reservoir; refill if low using DOT 3 brake fluid.
Check brake pads and rotors for wear, replacing if necessary.
Inspect brake lines for leaks; repair or replace damaged lines.

4. Battery and Charging System Check

Use a multimeter to measure battery voltage; should be around 12.6 volts when fully charged.
Start the engine and check voltage at the battery; should be between 13.7 to 14.7 volts to indicate proper charging.
Replace the battery if it fails to hold charge or shows low voltage.

5. Tire Pressure Adjustment

Use a tire pressure gauge to check all tires; adjust to manufacturer specifications (usually found on the driver’s door jamb).
Inspect tires for visible damage or wear; replace tires if necessary.
