Good Afternoon/evening/night

I have my 2011 XJR I bought used for cheap. It had 1 key and wasn't programmed properly as when I ran verify key in SDD v131, it shows no programmed keys. I do have a 60AMP Batt booster hooked up and Green Batt symbol in SDD

So I bought 2 more New keys and ran the Security - Replace faulty/lost keys, and was able to program the 2 new and the one that came un-programmed with it and they will unlock and lock the car and shows program successful to a point as it fails on the verify the keys when it tries to turn the ignition on and the Smart Key not Found pops up. Tried the emergency key location on the left dash under the trunk buttons but it doesn't recognize them.

I have read several posts that say the KVM needs to be programmed as new and then the BCM/IPC programmed as new to sync the new remotes.

So I ran Program KVM as new, it completed, then recovered keys, then re-added them, then I ran Security - Immobilization and it fails with " failed to write security identifier".

So I checked for DTC and had this


It says to try programming BCM as new, so tried that and

It resolves parts successfully, asks if module has been replaced, and I tell it no "red x"
then it reads info from current module
then it says to replace module and then I click ok then it says this



also tried again, and after it said replace module, I removed battery power for 30 sec , then hooked back up, then told it to continue and same error. Also tried in engineering mode and same error.

Not sure what to do now, what I read else where said the BCM needed to be "flashed" as virgin new but I don't know how to do it in SDD. Note I tried in SDD 160 as well and same issue.

Thank You for any help.

 

did you try answering yes to the cjb being replaced

sdd is so child proofed it makes you want to punch the wall

 

Yes, I went back I tried it both ways and with versions 131 and 160 of SDD and same error. I have made another laptop with version 150 I'll try, I'll likely get same error.

 

Was finally able to get it working.

Had to unplug the ABS module, there was weird errors for invalid data from abs module in DTC's so thought that may be interfering with data on the Can Bus.

Yanked ABS, then from SDD 131 , I was able to Program IPC as new, then BCM as New and everything started working, then plugged ABS module back in and it was working as well.

 

UPDATE! Got car started.....and now has turned into a headgasket job, or worse. Won't be able to know for sure until I get the heads off.
