Looking for others experience...my 17’ has had persistent U DTCs in the FCIM, after long research seems data overloads the FCIM and the U codes are thrown out. There are no physical issues everything works related to FCIM. Apparently there are updates for the strategy’s in the modules. Forscan shows multiple modules “latest known”
question 1. Forscan accurate with the latest known with my specific vehicle?
question 2. My dealer will not update modules unless a concern is present. While unlocking/remote starting my passenger and drivers mirror sometimes move to their limits and click until fob button, door lock/unlock or memory button touched. I can probably convince them to update those modules, but looking to get all the other modules updated to prevent the U code errors. So the question is, what are most dealers charging to update modules, one price for all or each module update cost?
