PCM Replacement

One of my jeeps (JK 2007 X) had a problem passing SMOG.
Went to dealer and they said that PCM need to be replaced, that power module inside failed.

And here is the shocker - they quote $1500 for PCM module and $2300 total with labor.

How hard is to replace PCM? (I guess it is pretty simple, plug-out and plug-in)
I see I can get it for ~$400.
What are the reliable sources for PCM?

Are PCMs and ECUs Different components? if not, replacing the PCM should take 20 minutes tops. I'm not sure the location on a '07, but on my '13 it is right in the open and only has a couple of bolts and two cable packs. IMG_2175.jpeg

PCM is essentially your fuse box. Power control module. It's not terrible to get out but it's not a 20 min R&R.

ECM or PCM? I think that term is used inter-changeable for 'computer box'.
I will get to dealership tomorrow to confirm what they are talking about.

I wonder if they talk about TIPM, the guy one the phone started to talk about power module, and than about computer ....

The issue is every manufacturer has their own acronym. I may have had that mixed up.
ECM- engine control module. (Engine only)
TCM- trans control module. (Trans only)
PCM- Power train control module. (Engine and trans.

PDM- Power Distribution module. (Fuse box)
TIPM- think this is Total Integrated Power Module (overpriced fuse box)

I was thinking PDM not PCM

UPDATE:

Confirmed - its PCM - 05150466AA - which needs to be replaced.
Apparently PCM is not sending correct signals to evap purge selenoid and that's generating bunch of 'check engine codes' and 'EVA' trigger is not clearing.

I will look for new/refurbished PCM and install myself ... no way to pay $2500 (part & labor) to dealer for it.
