How does the auto inhibit switch work?

I have an Auto that starts in Drive.

It was thought that the car may have had a manual ecu fitted at some time, but it has been T4’d by Jules who confirmed this is not the case. He has confirmed a correct auto ecu all correctly matched to the car, and suspects the auto inhibit switch may be faulty.

These are quite expensive so i wondered at first if anyone knows how they work, because the display in the message centre correctly shows the status of the gear lever, and knows that it is in Drive, yet still allows the engine to start.

So does the switch have 2 switch outputs in it? Does anyone know how to test one with a multimeter perhaps?

I believe this is the switch in question..
