Original RKE fob swap

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.

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?

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.

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.

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.

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).

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.
