U1000 on Gateway Module

[tnut55]

I am working on a 2103 Nissan Pathfinder Platinum (daughter's car). I have the judder code, a handful of PAST U1000 codes on various modules and a CURRENT code on the Gateway Module. Every connector I have looked at is immaculate as are the grounds. Fuses I have checked are OK too. But I have not checked everything. The car tuns fine and besides the judder code, I am most concerned about clearing the U1000 first. The only real problem is that the car will drop to limp mode with a MAF sensor code occasionally if she tries to accel too hard like in passing or a rapid decel. I think the car may have Inteligent Cruise Control but it does not report the module. I can reset the codes but of course the judder code comes right back as does the CURRENT code for the gateway module. I don't currently have the car but will tomorrow. I am just looking for a direction. It has a new battery and good, clean battery terminals. Alternator works and I don't believe there is a problem with power. I know there is a TSB on the gateway losing its mind but I don't have CONSULT, only X431 PROS Elite.

I know this is a difficult issue because it could almost be literally anything. So here is a more direct question that I hope someone can answer.

There is a TSB regarding this year Pathfinder regarding the CAN Gateway losing its mind and before replacing it, it should be reconfigured (as opposed to programmed) to tell it what modules are actually in the car. This is to e done manually, not scan the module and write it back.

The problem is that I don't know if the Launch ProS Elite can do this. I can see where other modules can be addressed but not the CAN Gateway specifically. Has anybody run across this?
