I have a 2000 dodge ram 2500 and it wont shift gears so I plugged in my code reader to see if it would pull up any codes and now there is no power to the port
My car has 160000 miles.
My car has an automatic transmission.
Often, this is caused by a blown fuse in the battery power circuit of the OBD port. It is pin #16 that is B+ on all modern vehicles, such as yours. It appears as though this is fuse #12 on your vehicle, which is a 10 amp fuse. This is located in the engine compartment junction box.
If this fuse is not the problem, I suggest you have a trained professional diagnose and repair this problem for you. The team at YourMechanic is an excellent option for an inspection of your shifting issue since we make house calls.
