I am in a remotely similar situation with my BMW. I may need to swap out the ABS/DSC control unit that bolts to the ABS hydraulic unit. They are coded to the car. In order to use a new part or even a junk yard part, I will have to recode it.
In the BMW world, I can do this by ordering an INPA (USB to OBD2 port cable) on Amazon which will come with the BMW INPA software as well as the NCS Expert software (the former lets you read all of the codes (OBD2, ABS, SRS etc) and with the latter, you can flip the DRL bits or even recode an ECU.
Something for the Jeep surely exists, even if it is still dealer only.
