Solution
1. Preparation
  • Tools Required: OBD-II scanner, multimeter, socket set
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
2. Advanced OBD-II Scanner Usage
  • Connect the advanced OBD-II scanner to the vehicle's diagnostic port.
  • Power on the vehicle without starting the engine.
  • Access live data and check for any manufacturer-specific codes that may not show on standard scanners.
3. Engine Ground Inspection
  • Locate all ground connections on the engine and chassis.
  • Clean any corroded connections with a wire brush and re-tighten to the manufacturer's specifications.
4. Battery Voltage Check
  • Set the multimeter to the DC voltage setting.
  • Connect the positive lead to the positive battery terminal and the negative lead to the negative terminal.
  • Ensure voltage is within the normal range; if not, check for battery or alternator issues.
5. ECU Reset
  • Disconnect the negative battery terminal using a socket wrench.
  • Wait for at least 10 minutes to ensure a full reset of the ECU.
  • Reconnect the negative terminal and ensure it is tight.
