Solution

1. Preparation

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

2. Addressing Check Engine Light

Sub-step 1: Using the OBD-II scanner, clear any stored trouble codes after noting them down.
Sub-step 2: If the check engine light reappears, use the codes to diagnose specific issues (e.g., replace faulty sensors or components).

3. Fluid Level Check

Sub-step 1: Check engine oil level using the dipstick; add oil if low.
Sub-step 2: Inspect coolant level; refill if necessary.
Sub-step 3: Check brake fluid level; top off if low.

4. Battery and Charging System

Sub-step 1: Measure battery voltage with a multimeter; it should read 12.6V or higher when the engine is off.
Sub-step 2: Start the engine and check the voltage; it should be between 13.7V and 14.7V.
Sub-step 3: Replace the battery or alternator if readings are outside the specified range.

5. Brake System Inspection

Sub-step 1: Visually inspect brake fluid reservoir for leaks or low fluid.
Sub-step 2: Check brake pads and rotors for wear; replace if necessary.
Sub-step 3: Inspect brake lines and connections for any signs of damage.
