Thanks for the info Urban! I hear you about purchasing spares, good idea.
As I started to have issues with the BCM I was a bit surprised there wasn't a sticky thread with definitive information about the BCM's in XF's. As we inch closer to owning 20-year-old vehicles and have to rely on parts from junkyards, it would be good to at least have some solid information about what to look for regarding specific version (base, limited coupe, limited convertible, SRT coupe, and convertible) based on year.

If you feel up to it, perhaps we can get some posts with the info from BCM and car (year/model).

Cheers bud.

Edit: I also plan to have a look at my old BCM to see if there is anything I can re-solder to get the driver's window functionality working again. If anyone has tried to repair a bcm, it would be good to hear about the effort.

 

You were right bud...it was a date indicator. Makes me feel better now since all my other numbers match. We'll see on Friday.

 

One more thought on this and I don't know the answer, just throwing it out there.
Could there be 4 different BCM's for the N/A
-Roadster AT
-Roadster MN
-Coupe AT
-Coupe MN
I'm not sure if the transmission needs to be factored in when purchasing used BCM. The SRT were only available in Automatic so only need to confirm Coupe or Roadster.
I hope the part that arrives on Friday provides you with the fix, Keep us posted.

I think the only way to know for sure that you will be getting a BCM that will have all the same programmed functions as the original one on your car is to find one that was removed from a U.S model Limited Auto Trans Crossfire. I do think the transmission is a programmed factor on a NA BCM. (Clutch switch input to allow it to crank on start or shift lever in P or N on automatics)
It is the programming of the BCM that matters as all the used replacements on ebay carry the same part number as the original. Even a new replacement from Chrysler if you could get one would have to be programmed to the different functions on your car.
I believe you are more likely to get one from ebay that will match to your car considering the bigger number of U.S model Limited Auto Trans cars vs others

 

I hear you and it's a crapshoot looking for something online because not all the listings have the donor car model listed nor the Vins (some do but not all). The seller I"m buying from is in Wisconsin, so at least US-based. If it doesn't work at least I can return it (confirmed with the seller before I bought it).

Unfortunately, it's just one of those things we're going to deal with as the car gets older.

 

I wonder with a DRB 3/emulator can you reprogram a used BCM to make it work?

 

You could even reprogram your original BCM and turn off functions like TPMS or switch from active to fixed spoiler. It shows up on the screen as a menu of functions that you can turn on/off or even change parameters on some cars. Never had the opportunity to use a Chrysler DBR or an emulator but i have used other manufacturers tools and it is fun to see all the possibilities it give you.

 

Well, gentlemen, I received the new BCM earlier today, swapped out the old one and it works perfectly. Driver side window works flawlessly as do all other things connected to the BCM. Not to count my chickens before they hatch, I'll reserve a complete declaration of victory until after a few days. Thanks for all your help!

 

Good news. thanks for the update.

 

Good to hear it all worked out..

 

How did you install it? Did you put the car in the accessory position like others have so the car can learn the BCM?

 

Ron,
It's really just a plug and play install. I undid the top section of the BCM with all the wire connectors attached. Removed the remaining BCM body, put in the new one. Reconnected the top section, put the power plug back into the bcm, and reconnected the battery. Turned the key to the "on" position (not running) and waited 60 seconds - this is apparently how the car and the BCM sync up. That was all there was to it. As I said above, all the numbers matched on the Old and New BCM except for the last five in the TEMIC, but I think we all agree that was the build date (for the BCM) and it was very close to the original.

I didn't have to do anything special. I've tried all the windows and the seats, spoiler, lights, radio....everything seems to be working on day 1.5.

 

Wow, I didn’t even know you had to wait 60 seconds to sync it. When I swapped mine I plugged everything jumped in and turned the key and fired it up. No waiting, Oops

Mine works perfectly too.

 

Urban,
I don't know if it's required or not (guess you're proof it's not) but I read somewhere in a BCM replacement thread that waiting 30-60 secs with the key in the "on" position was required. This is another reason it would be good to have a sticky thread about the BCM repair and/or replacement so we can get all this information verified and in order.

 

Thank my friend, thanks for the help and good to hear from you!

 

I think you are thinking about a new SKREEM module being installed. I got one as a spare, put it in and started the car, it ran fine so I left it in.

 

I think that's right, but I figured better safe than, it couldn't hurt. Alls well that ends well.
