OK if you don’t know what the (DIC) is it stands for Drivers information Center and I have one on my new truck but the problem I’m having is switching drivers the truck came with two sets of keys and keyless entry transmitters one is marked driver 1 and the other is driver 2 when you put each key in the ignition it is supposed to bring up the settings for each driver, but when I put driver 2 in it just said driver 1 and goes to my settings then I used the driver 2 key for a while it finally switched to driver 2, so the I put driver 1 back in and it still said driver 2, then the next time I went somewhere with the driver 1 key it said driver 1 like it should, now I’m trying to program some settings for driver 2 and it wont come off of driver 1. This is starting to frustrate me very badly since there is very limited info about this in the owners manual. If anyone has experience or any knowledge it would be greatly appreciated!
