Solution
1. Preparation
  • Ensure the vehicle is parked on a level surface.
  • Turn off the ignition and ensure all electrical components are turned off.
  • Gather necessary tools: OBD-II scanner, socket wrench set, and possibly a multimeter if further electrical diagnostics are needed.
2. Addressing Underlying Issues
  • Use the OBD-II scanner to retrieve any diagnostic trouble codes (DTCs).
  • If codes indicate issues, perform repairs as necessary (e.g., replacing a faulty sensor, fixing a vacuum leak).
  • Clear codes using the scanner if repairs are made.
3. Resetting the Check Engine Light

  • Disconnect Negative Battery Terminal:

    • Locate the negative terminal on the vehicle's battery.
    • Use a socket wrench to loosen the bolt and remove the negative cable.
    • Wait for approximately 5-10 minutes to allow the vehicle's computer to reset.

  • Reconnect Negative Battery Terminal:

    • Reattach the negative cable to the battery terminal.
    • Tighten the bolt securely with the socket wrench.
4. Verify Reset
  • Turn the ignition to the "On" position without starting the engine.
  • Observe the check engine light; it should illuminate briefly and then turn off.
  • Start the engine and verify that the check engine light remains off during operation.
