Solution

1. Preparation

Tools Required: Safety gloves, safety glasses, ratchet set, OBD-II scanner.
Allow the engine to cool down before starting work.
Park the vehicle on a flat surface and engage the parking brake.

2. Inspect Engine Oil

Sub-steps:
- Remove the engine oil dipstick and wipe it clean.
- Reinsert the dipstick and remove it again to check the oil level.
- If the oil is low or appears burnt, proceed to change the oil.
Safety Warning: Hot oil can cause burns; let the engine cool before handling.

3. Change Engine Oil (if necessary)

Sub-steps:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug and allow the old oil to drain completely.
- Replace the drain plug and torque to manufacturer specifications.
- Remove the old oil filter using an oil filter wrench. Install a new oil filter, lubricating the rubber gasket with new oil.
- Fill the engine with the appropriate type and amount of new oil.
Torque Specification: Refer to the owner’s manual for drain plug torque values.

4. Check Electrical System

Sub-steps:
- Inspect all visible wiring for signs of wear, fraying, or melting.
- Repair or replace any damaged wiring or connectors identified during the inspection.
Tools Required: Electrical tape, heat shrink tubing, or new wiring as needed.

5. Inspect Transmission Fluid

Sub-steps:
- Locate the transmission dipstick and pull it out.
- Check the fluid level and condition; if burnt, prepare to change the transmission fluid.
Safety Warning: Transmission fluid can be hot; proceed with caution.

6. Change Transmission Fluid (if necessary)

Sub-steps:
- Follow the manufacturer’s recommendations for draining and replacing transmission fluid.
- Make sure to replace the transmission filter if applicable.
- Refill with the recommended type of transmission fluid.
