Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, coolant tester, brake cleaner, multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before working on any electrical components.

2. Inspect and Replace Engine Oil

Sub-steps:
1. Remove the oil dipstick and check the oil level; add oil if low.
2. If oil appears burnt (dark, thick), drain the old oil using a wrench to remove the oil drain plug.
3. Replace the oil filter with a new one.
4. Refill the engine with fresh oil as per manufacturer specifications (typically 0W-20 for this model).
5. Torque the drain plug to the specified value (typically 20 lb-ft).

3. Check and Refill Coolant

Sub-steps:
1. Inspect the coolant reservoir and radiator for leaks.
2. If the coolant level is low, top it off with the appropriate type (typically Honda Genuine Coolant).
3. Inspect hoses for cracks or wear; replace if necessary.

4. Inspect Brake System

Sub-steps:
1. Remove the wheel and inspect the brake pads and rotors for excessive wear.
2. Replace worn brake pads and ensure calipers are functioning correctly.
3. Clean any debris or burnt material from the brake components using brake cleaner.

5. Electrical Inspection

Sub-steps:
1. Inspect wiring and connectors in the engine bay for signs of damage or melting.
2. Use a multimeter to check for any shorts in the electrical system.
3. Repair or replace damaged wiring as needed.
