Solution

1. Preparation

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

2. Addressing Diagnostic Trouble Codes (DTCs)

Use the OBD-II scanner to clear any stored error codes after making necessary repairs.
Note down any persistent codes for further investigation.

3. Battery and Electrical System Inspection

Reconnect the battery terminal and start the vehicle.
Use the multimeter to check the battery voltage; it should read between 12.4V and 12.7V.
If the battery voltage is low, consider replacing the battery.

4. Brake System Check

Inspect the brake fluid reservoir for proper fluid levels; refill with the manufacturer-recommended brake fluid if low.
Check for any visible leaks in brake lines or calipers. Repair any leaks found.

5. Cooling System Inspection

Open the hood and inspect the coolant reservoir for proper fluid levels. Refill with the appropriate coolant mixture (50/50 antifreeze and water).
Check for any external leaks or signs of a failing water pump or radiator.
