  2. Turn the ignition key to “On,” but leave it in that position withoout starting your car’s engine.
  3. Using a paper clip or wire, jump the terminals by connecting the positive and negative connectors.
  4. The check engine light will blink codes. Count the number of blinks for the first digit of the code, wait for a short pause, then count the number of blinks for the second digit. Repeat this process for each code that is displayed.
