The warning did not warrant a failure and any irregularities in such and similar systems can deteriorate very fast. Instead of taking the risk of further flight to Chicago, the flight crew decided to divert to the nearest henceforth major airport, which was Denver with highly developed emergency facilities.
Those are just some examples of such diversions of which the safety-first culture that commercial aviation promotes testifies.
