Hello and welcome to JustAnswer!

If you're seeing a message that the function is disabled it's due to failure being seen and a fault code setting. It's seeing an issue in a component that would prevent proper presafe operation.

While the problem does have to be prevent for testing there should have still been fault codes stored. Do you know what codes were stored?
