Solution

1. Preparation

Tools Required: OBD-II scanner, basic socket set, multimeter, safety glasses, gloves.
Allow the engine to cool down before starting any work to prevent burns.

2. Address Engine or Electrical Issues

Step 1: If error codes indicate an electrical issue, disconnect the vehicle battery (negative terminal first) to avoid shorts.
Step 2: Inspect wiring harnesses for frayed or damaged insulation. Repair or replace any damaged wires.
Step 3: Check the alternator and starter connections for corrosion or loose connections. Clean and secure them as needed.

3. Check and Replace Fluids

Step 1: If fluid levels are low, identify the source of the leak (e.g., oil pan, coolant hoses). Repair the leak before adding new fluid.
Step 2: Replace any low or contaminated fluid, ensuring to use manufacturer-recommended types (e.g., 5W-20 oil, Dexcool coolant).

4. Brake System Inspection

Step 1: Inspect brake pads and rotors for excessive wear. Replace if necessary.
Step 2: Check the brake calipers for proper operation and no sticking. Lubricate and adjust as needed.

5. Reassemble and Reconnect

Step 1: Reconnect the battery, ensuring the negative terminal is connected last.
Step 2: Start the vehicle and observe for any further smells or warnings.
