How can I tell if a flash has been done?

I was reading about TSB#08 082 16 which has to do with trailer brakes not being recognized.

How can I tell if this has been applied?

Heading out for a 3k mile trip in a couple of weeks, I want to make sure I have trailer brakes.

The vehicle Must be connected to Dealer account or Tech Account VIA WITech, it will search for updates, when 1 is available a lighting bolt will be shown on the modules Icon.

So is the Witech a gizmo I need to buy?

Just go to the dealer, the service advisor can check your truck in the service drive for any updates your truck needs, quick and easy.....the Witech is a high dollar scanner used by the dealer techs.

Yes, an expensive gizmo with an even more expensive subscription to Tech Authority to make it work. Have the dealer check and perform any updates so if something goes wrong it is their issue.
