Solution

1. Preparation

Gather tools: OBD-II scanner, tire pressure gauge, multimeter, socket set, and torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery before working on electrical systems.

2. Address Check Engine Light

Sub-step 1: Connect the OBD-II scanner to the vehicle’s diagnostic port.
Sub-step 2: Retrieve and document any error codes.
Sub-step 3: Research the error codes and address the specified issues (e.g., replace faulty sensors, clear codes).

3. Check and Refill Fluids

Sub-step 1: Inspect engine oil level using the dipstick; add oil if needed (use manufacturer-specified oil).
Sub-step 2: Check coolant level; add coolant if necessary (use the approved coolant type).
Sub-step 3: Examine brake fluid level; refill if low with the correct brake fluid type.

4. Tire Pressure Adjustment

Sub-step 1: Use the tire pressure gauge to check each tire’s pressure.
Sub-step 2: Inflate tires to the manufacturer's recommended PSI if low.
Sub-step 3: Reset the TPMS according to the vehicle's manual.

5. Battery Inspection

Sub-step 1: Inspect battery terminals for corrosion; clean if necessary using a wire brush and a baking soda solution.
Sub-step 2: Tighten battery connections using a socket set.
Sub-step 3: Test the battery voltage with a multimeter; replace if voltage is below 12.4 volts.

6. Brake System Check

Sub-step 1: Inspect brake fluid level and condition; replace fluid if contaminated.
Sub-step 2: Check brake pads and rotors for wear; replace as needed.
Sub-step 3: Test the ABS system using the OBD-II scanner for any fault codes and address them.
