Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather tools and necessary parts for repairs.
Disconnect the battery to prevent electrical hazards.

2. Address Error Codes

Connect an OBD-II scanner and retrieve error codes.
Research each code to determine if they require specific repairs or resets.
Clear the codes and monitor if they reappear after a test drive.

3. Inspect Electrical Systems

Check the battery connections and cables for corrosion or looseness.
Test the battery voltage using a multimeter; it should read between 12.4-12.7 volts when the vehicle is off.
If the voltage is low, consider replacing the battery.

4. Brake System Inspection

Inspect the brake fluid reservoir for proper fluid level; refill with manufacturer-recommended fluid if low.
Examine brake pads and rotors for wear; replace if necessary.
Check brake lines for leaks or damage and repair as needed.

5. Tire Pressure Check

Use a tire pressure gauge to check each tire's pressure.
Inflate tires to the manufacturer’s recommended PSI.
If any tire shows abnormal wear, consider a rotation or replacement.
