The code you pull up is from the steering wheel. The flash code you need is off the engine light. You can call International but unless you get the right person you wont get a answer. The easiest thing to do is start and run the engine until warm. Take a heat gun point it at the exhaust manifold and read what cylinder reads cold. That will be the problem cylinder.
