The driver door module only effects window operation not RKE operation. This system has an antenna in the door that communicates with the WIN directly.

I believe you can switch door modules because they are told what the VIN is and do not require programming. However, just make sure it is the same part number as yours or it could be equipped differently and your window operation may not work right.

Could installing a different door with different internal parts(ie: DDM) to car create a dtc of "RKE fob giving off scrambled messages" and showing its original mileage as the mileage of the car the different door came from?

No. The DDM does not need to be programmed. If you install a door with all the components on it, it should be fine. The antenna is plug and play and the DDM does not require any programming. I have to stress if they are different part numbers from your stock ones then it will have performance issues. Otherwise you should be good.

So why would RKE Fob give off a Dtc code of "B1A09-fob 2 performance" with original miles and current miles - same as car used door came from?

Again, this has nothing to do with the DDM. Here is the testing for this code. I suspect you have an issue with this FOBIK. Basically this is just saying that the FOBIK is out of sync with the rolling code of the WIN.

Why would a scan report showing dtc of FOBIK display FOBIK's original mileage and current mileage that of the car the donor door module came from instead of mileage of car its for?

Can you get a picture of the scan report so I can see it?

The only thing I can think is the DDM had that code in it from the last vehicle and when it sets the code it gets the environmental data reported to it because it doesn't store mileage on its own. So most of that info is from other modules. Does the code clear or is it active and not clear?

Just get a picture of each of the pages for the scan report so I can see all the module info as well as the DTCs and data. Thanks

The thing is the donor DDM shows its original mileage as 4 miles prior to mileage of when it was installed and the current mileage for DDM is when scan report was done. It's on same scan report that FOBIK shows the donor car's mileage. How can that be?

Okay. I think I am going to need to see the scan report to get on the same page with you. I am intimately familiar with scan reports so I know what you are referring too but if I see it I am sure I will be able to explain it. You can just take pictures of it and upload them. You don't need to scan it to a computer or anything like that.

I am familiar with the scan report but not with what you are saying the mileage is different based on the previous vehicle. That is why I want to see it. In general the original mileage is when the code was first set and current mileage is when the scan report was pulled.

If the code is active, do you know if the code was active in the donor vehicle? I can't imagine this code is causing any issues but it is, have you driven the vehicle over 5 MPH and checked to see if it went stored? See attached. If it does not then you need to program all the keys to the vehicle.

I understand you don't have it but if you get a copy, I wouldn't mind seeing it and I can probably give you more detail.

Why would a FOBIK be affected by donor vehicle "active" DTC? If donor door module doesnt need to programmed if same part number?

What was changed in system to allow the 2013 door modules not need programmimg when being replaced but require the 2011 door module(s) be programmed when replaced? (As well as: why does the 2011 allowing only a single door module be replaced instead of both door modules at same time, in contrast to 2013 requiring both modules be replaced at same time?)

Are you able to clear the active DTC by driving the vehicle with this key?

If so, then there is nothing to worry about. As for programming a 2011 vs a 2013, this is no different. I am not sure where you are getting your info but I am not sure it is accurate. If you look at the info provided, the door modules are NOT programmed once they are flashed. So that means you install the door module in the vehicle and then you flash it with the software for that specific vehicle which tells the module how it is equipped. Once this is done, it does not have to be flashed again. However, if you install this in a vehicle that is not equipped the same then it may not function properly. However, as long as they are the same part number this will not be an issue because all the DDM is control the window operation.

As you can see in the service info, the DDM gets additional information provided to it by other modules via the CAN bus. This is where it is getting the mileage info.

I can't imagine any of this is causing an issue so again, are the windows operating since you put this module in and have you gotten the code stored? Please read the code info. This code doesn't not have anything to do with the DDM. It says that if the code remains active replace the key.

Thank you for your reply. No the fobik DTC remained active while driving as well as not updating its mileage. Now the dash will periodically state: "Fob not detected", even while driving. Also- car will unlock with fob but will not lock with fob. Plus the rear seats seem to be glued into position removing ability to access the transponder/ immobilizer easily. This seem odd to you? Why would someone go to the trouble doing that to someone elses car?

Also- if the DDM gets it's mileage info via the can bus from other modules, how come in the scan report it says that the original mileage is actually 4 miles less then the mileage on odometer of car when the donor DDM was installed? The other modules show correct mileage at same time as this.

Sounds like you need a new FOBIK.

I will need to see the scan report at this point. Again, I am sure I can explain it but you have asked the same question a few different times in different ways and I thought I was answering it, so maybe I am not understanding what you are referring to so I am going to need to see it.
