Full Answer

  1. Disconnect the battery

    Park the vehicle in an open, dry location where the sound of the horn will not disturb others. Do not attempt this procedure when it is raining. Put on rubber gloves, open the hood, and disconnect both battery terminals.

  2. Drain the residual power

    Put on ear protection. Place the vehicle key in the ignition, turn on all of the lights, and honk the horn repeatedly. When the lights go off and the horn stops sounding, the vehicle has no remaining electrical power.

  3. Reconnect the battery

    Remove the key from the ignition, and reconnect the battery terminals. Verify that the positive cable connects to the positive terminal, and the negative cable is attached to the negative terminal. Close the hood, and remove the rubber gloves.

  4. Start the vehicle

    Start the vehicle, turn off the lights, and examine the console. If the check engine light is not illuminated, the reset was successful. If it remains lit, repeat the reset procedure.
