Original RKE fob swap

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.

So the replacement driver door module does not need to be initialized/programmed to system/ECU If same part number?

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?

And the FOBIK DTC is active.

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 not trying to be difficult sorry. But i don't have it on me right now.. if you know what i am referring to, can you please explain it ? Thank you for your help.

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?

Why would FOBIK be displaying donor car mileage instead if donor door module?

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.

Again - apologies if im not clear enough. I do not have the scan report on me. I do not know how my questions are the same , my last question was regarding a totally different situation with the DDM not FOBIK. What i need is possible reasons why a module would or could display these readings and why?. If you cannot help me, could you please refer me to someone who might? Thank you for all your help thus far, much appreciated .

If you look at the attachment, this is a vehicle that had a code with the mileage recorded. The original odometer value is the first time this code was set. The Most recent odometer value is the last time the code was set. The purpose of these mileages is so the one diagnosing the vehicle can determine about how many miles it may take to replicate the issue.

If your DDM module is showing the mileage from the last vehicle, that is because whatever code you are reviewing was set in that vehicle. The only time the environmental data is recorded is when there is a code set.

I wanted to see the scan report so I can be sure this is what you are talking about. If it is then the mileage was recorded the first time the code was set and then the '"Most Recent" mileage is set each time the code is reset. If the code is only set one time then this mileage will be the same as it is in the example attached. If the code is Active, then goes stored, then goes active again, it will keep the original mileage from the first time it set, then record most recent mileage at the next time it set.

Thank you for your response. What about the RKE FOBIK showing the other cars mileage? As original and current mileage? If what your saying is true about mileage and DTC's - then would that indicate that the Fobik is from the other car as well as the DDM?

I am not sure I understand. This is why I am asking to see the scan report. I get that you don't have it but I feel like I am answering your question about the mileage but then you ask it again. Where is the RKE FOBIK showing the other cars mileage? On the scan report under the code for the FOBIK in environmental data? If this is the case then this is because the code was set in the other car. So now that you installed it in this car the module had that data in it.

What module is the code set in? Then DDM? If the key was from the other vehicle then it would not start your vehicle. I think you are confusing the function of the DDM with other systems. The DDM only operates the window function and communicates with the other modules. It doesn't actually control the RKE function.

What do we have to do to get the scan report? Was the report pulled from a dealer? Can you give me the last 8 of your VIN?

The DDM was the only module pulled from the other vehicle . The RKE Fob is supposed to be the original, but is showing different mileage than any other module including the DDM. The DDM from the other car that was installed onto my car, shows my car's mileage . But, the RKE Fob shows the same mileage for original mileage and current mileage , that of the other car- that it supposedly didn't come from. So my question is: how can the RKE Fob for my car be showing the other car's mileage if the DDM does not have anything to do with the Fob and doesn't need to be programmed ( same part number) and it , itself , is not showing the mileage of the car it came from?
Is that clear enough? Apologies if i am not making it understandable, i don't mean to.

I need to see the report because the terms you are using are what I think are not making sense. I am not sure how the RKE FOB has any mileage or where you are seeing this. This is the key that you use to start the vehicle and not a module so I am not sure what you are seeing with mileage next to it.

If you give me the last eight of your VIN I may be able to pull the report if you had it done at a dealer.

No apologies needed. We just aren't on the same page but we will get there. Once I can see the report, I think all questions will be answered.

Apologies again, its the WCM module that set the DTC: "key fob 2 performance" with the other car's milleage. So sorry i did not mention that.

Okay. I figured that last night when I woke up thinking about this one. So that means we are getting closer. Now can you tell me what the mileage was for each line of original mileage and most recent mileage. Then tell me what the mileage was on the donor vehicle and the current mileage on your vehicle? With that information I think we can make sense of all this.

Just to recap, I need 4 things:

1. Original mileage from the WCM of the RKE code from the scan report.
2. Most recent mileage from the report.
3. Donor vehicle mileage.
4. Current mileage of your vehicle.

Original mileage of WCM : 93650.
Current mileage of WCM: 93650.
Donor vehicle mileage: 93650.
Current mileage of my vehicle: 112789.

Okay. So you are sure that the DDM was the only module used from this other vehicle? The reason I ask is the DDM does not retain the mileage. However, this RKE code was not even set in the DDM, it would have been set in the WCM. This means the only way the WCM would know what the mileage was of the other vehicle, is if it was in the other vehicle.

So just to try and recap. You swapped the DDM from another vehicle and had a DTC in the WCM for the key performance and this was the mileage data that you found on the scan report? If this is the case, then the WCM wound not get the mileage from the DDM because the DDM has no way of knowing what the mileage is. Again it's only function is window operation and it does not need mileage for that.

So the WCM would have to be from the other vehicle as well. Thank you so much, that is what i was thinking too. You have been an enormous help.

If the PCM is throwing a "no communication with radio" -DTC, does that mean the radio will not work while driving ?

What does it require when installing a used WCM into another vehicle? Would it automatically work with car's PCM, TCM and ECU?

Would the PEM work with anothee car's WCM?

No. The PCM no communication with Radio is very common to see. Basically this means at some point the PCM was expecting to see something from the radio and it didn't get the proper "response" from the radio. I have seen these codes active and the only way you know it was checking the codes. These communication errors alone do not effect the operation of the individual component. It simply says the two modules did not communicate properly. Its like a poor cell phone connection. Both phones are still working, they just can't talk to each other.

If the WIN/WCM was used from another vehicle then yes it would need to be programmed to the PCM because the info is backed up in the PCM. This would be an easy process as it just needs the WIN replaced function and program the keys, then the PEM (passive entry) replace function (if equipped).

Would replacing drivers side outer door handle require replacing WCM, FOBIK and PEM?

If the driver side door outer handle's wiring harness was damaged or broken, would that require replacing the WCM? And /or would that cause the other cars mileage to show on scan report if the wiring harness to the outer door handle was from other car ?

No. The door handles are inputs only to the passive entry module and can be replaced with no programming. Basically the antenna in the door senses the programmed key is within range. The PEM tells the BCM that when your hand goes onto the handle it is ok to unlock the door. So this means the handle is only a sensor and does not require any programming.

Thank you very much you have been very helpful.

What if the wiring harness to the door handle was damaged, would that require or be easier to just replace the WCM?
