Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Addressing Error Codes

Sub-step 1: Connect the OBD-II scanner to the vehicle's diagnostic port located under the dashboard.
Sub-step 2: Turn on the ignition without starting the engine and read the error codes.
Sub-step 3: Note down any error codes and refer to the service manual for specific troubleshooting related to each code.

3. Rectifying Fluid Levels

Sub-step 1: Check the engine oil level using the dipstick; add the appropriate oil if low.
Sub-step 2: Inspect the coolant reservoir and refill with the recommended coolant if necessary.
Sub-step 3: Check the brake fluid level and refill with DOT 3 or DOT 4 fluid as specified.

4. Tire Pressure Adjustment

Sub-step 1: Use a tire pressure gauge to check the inflation of each tire.
Sub-step 2: Inflate or deflate tires to the manufacturer's recommended pressure (found on the door jamb).

5. Brake System Inspection

Sub-step 1: Visually inspect brake pads for wear; replace if they are less than 3mm thick.
Sub-step 2: Check the brake fluid reservoir for low fluid levels; if low, top off and inspect for leaks.

6. Battery and Charging System Check

Sub-step 1: Use a multimeter to check the battery voltage; it should be between 12.4 to 12.7 volts.
Sub-step 2: If voltage is low, consider charging the battery or replacing it if it fails to hold a charge.

7. Reconnect Battery

Reconnect the negative battery terminal securely after all checks and repairs are completed.
