I have a Jaguar XE 2017 and I have no communication with RFA and due to this I cannot turn on ign. I tried to write virgin data to bcm and even after then I cannot communicate with rfa or any other modules. I can communicate only with BCM IPC ABS modules. I have attached the DTC here in mail. Can anyone help me with this issue? I guess it need some bcm config in order for other modules to communicate.

 

Have you checked the power/ground/CAN at the RFA? It's possible the module just failed. Not sure what operation you ran on the BCM but that doesn't sound like it was a good idea. A failed RFA will not be fixed by configuration issues in the BCM, and rewriting a BCM with other theft relevant modules off the network could lock it up as well.

 

Vehicle needs a good working RFA/KVM for ignition to come on, no way around this.

Check and confirm wiring is good 100%, if that passes most likely its defective or water damaged. A new rfa/kvm from dealer is not expensive, or a used part and virginize it. As far keys, you can use your original keys if they are good, if not get two new dealer or aftermarket keys...

Put any ccf changes back to asbuilt original, dont make any changes you wont be able to get ignition.

Ccf settings is limited to how the engineers designed this platform, not everything you think of is possible with modifying ccf .
