For my sake—and for others in the same situation—could those with firsthand experience share which BCMs are cross-compatible across different model years, with a focus on forward compatibility (for example, whether a 2015 can use a 2019 BCM, etc.) on 4th Gen and Classics?
There’s already a lot of discussion here, there and everywhere about swapping BCMs between 2013–2015 trucks to the 2016 or 2017 units for specific features and benefits. The goal here is to consolidate accurate information and clarify what works when using newer model years.
It’s already well-established that BCMs from 2013–2017 are interchangeable within that range—for instance:
* 2013 can go to 13, 14, 15, 16, 17.
* 2014 can go to 14, 15, 16, 17.
* 2015 can go to 15, 16, 17.
* 2016 can go to 16, 17.
* 2017 can go to 17.
Now for the real questions:
1.) Can a 2013 to 2017 swap to a 2018 or 2019-2024 Classic?
2.) Or even a 5th gen, 19-22 or 23-25?
3.) If so, would there be any more to the swap than the normal process well documented given 13-17 do not have the security like the 18+?
4.) If possible is there an issue with using a used vs new?
5.) If possible, does the process of writing the config file from the 13-17 to the 18+ still apply or would you just write the vin and then manually change all the configurations?
6.) Concerns with US vs Canada or any other country code? i.e. a Canadian truck swapping in a US one, vise versa?
7.) VehConfig 1: Country Code vs ECUConfig 3: Country of Destination?
For me personally I am wanting to confirm prior to making purchases on BCM's to solve compatibility issues I am experiencing with my 2015 with a 2016 BCM swap and a UConnect 5 12.1 radio, more specifically HVAC issues, everything else works fine or to be expected. I am in the United States and bought a used Canadian truck, so there is that aspect for me directly if that has any effect as I am wondering that if by swapping in either a classic BCM or even a 19-22 or going all in on the latest 23+ BCM would solve my issues or not or if those would even work when writing a 2015 config file to them. I simply cannot find anyone speaking to the 18+ BCM's in a 13-17 to help...
