What year did Chrysler/Dodge start blocking access to OBD2 info?

My Bluedriver OBD2 dongle has no problem accessing the various computers and modules on my 2014 Durango. However, it can only read the basic OBD2 info on the wife's 2018 Durango. I have heard from various sources that Chrysler/Dodge did something to block access to anything other than the basic info in recent years.

Is this correct? And does any non-Chrysler OBD2 device access this information (and costs less than $1000+)?

I found that the basic code readers that the auto parts stores use don't pull any codes from my wife's 16. I bought an app for my phone called AlfaOBD, along with a Bluetooth OBD connector. Total I'm in for about 200 ish. It can read codes from any module, it works on any FCA product from 06 on, and you can even change some parameters. Look up the app on Google, it will give you all the info you need.

I recommend JScan

It’s only for FCA vehicles. Has the ability to change some things (i.e. LED drop when turn signals on), dashboard for live data, & only ~$60 between the VIN license & Bluetooth connector

Thanks, I`ll have to read up on scanners here. I`d prefer to use a scan tool, ie: Innova, Zurich, etc.

You can do LED drop from the settings in UConnect. Pretty much the only thing I have found JSCAN useful for changing things is enabling fog lights when high beams are activated. Not much else can be manipulated.

Gotcha. I haven’t explored it too much for DD. I feature I use the most is live data for the temperature readings.

JScan is extremely useful on my Wrangler (it allows use of the lockers in 2WD & 4H)

Well, an update:
1) What I was referring to is that automotive manufacturers are required to allow for capturing basic information related to OBD2 information regarding the check engine light, reading ENGINE codes, etc. Modern vehicles basically now have dozens of modules/computers in them (for example, there is a module per door just to control the door locks, power windows, etc.) but to access any trouble codes requires access to "enhanced codes" Older, cheaper OBD2 devices typically do not have the ability to read transmission, air bag, etc. modules and their trouble codes.
2) It turns out that my BlueDriver OBD2 device can indeed read these enhanced codes in the various modules. Mea culpa!

It turns out that my BlueDriver OBD2 device can indeed read these enhanced codes in the various modules of my 2018 in addition to my 2014.
