Are the BCM or body control modules the same for all crossfires or is there a difference between the SRT and the base and limited models?

would like to know because mine might be bad.

 

I could be wrong here, but I was under the impression that at the minimum there is indeed a difference between SRT and limited/base because of the retractable spoiler.....

 

I believe you are correct.... and I also believe that the VIN is coded into the BCM, like the ECU....

 

Did yiou ever get an anwer on this? If not, I can tell you that they are indeed different. I found out after replacing the BCM from my SRT-6 with a BCM from a conventional XFire.
I bought the BCM online from a parts guy - Chrysler price was stupid, and they would not guarantee the part. Installation of second BCM fixed the original problem - passenger window stopped working - but a new problem cropped up. At 80 mph, car now started to chirp. Why, because the BCM was looking for a signal from the retractable spoiler that it had been raised. Since there was no spoiler feedback to the BCM, i now hear CHIRP CHIRP CHIRP above 80 mph. Sort of spoils the driving experience on the freeway.

The only way to fix this issue may be to have the BCM reprogrammed at the Crhysler dealer with SRT6 codes using a TekII device. Unless someone out there has one, and is willing to give this a whirl.

 

Did you have to have the VIN programmed into the new BCM or was it just a plug and play?? Inquiring minds want to know....

 

Nothing extraordinary with the VIN. Installed BCM into the car using the procedure described on the AllDataDIY website for the Crossfire SRT-6. Turned on the key for 1 min before starting the car. BCM did its job perfectly - even sentry key remotes - no need to reprogram BCM at the dealer, which would have cost $100 for installation + $100 for programming.

 

Thanks... that sounds like it uses that first minute to sync up with the ECU and then all is fine...... cool!

 

jmlasker -


Did you buy your BCM as a used part online or at a junkyard? Did you just make sure you were buying one that came from a same model year Limited or ???

 

Good luck getting a response on a 6-year old thread!

 

Nope they are definitely not all the same... There are all kinds of variations. Different software etc...
I had a issue with mine last year.
I purchased one that almost matched. It fixed my problems but now the spoiler stays up and Bas esp light is always on... Hence you should get one with a perfect match to have a hope in hell lol. There are 5 sets of numbers on a Bcm. I would get one that is a perfect match...
I now found one that is a perfect match.. I should get it in a week or so and will install it and see it will make everything like new... Or not... I will let you know when I do... My previous one that I bought had 4 sets that were the same and one set that was slightly off.. I took a chance and bought it.. It worked for me for last summer but I want to get my spoiler working properly etc... So here's to hoping with the exact match....

 

So................. Trying to fit a LTD BCM into an SRT-6 with the objective of putting a fully-functional deployment skateboard spoiler on appears to be just fools gold then...... Maybe I get the spoiler to work great but then the windows wont roll down when I'm done?


I'm starting to get the picture here...

 

The #'s are usually the same on all of them - I could only find 2 different part #'s but they need to be from the right car. I tried an SRT coupe on my Ltd roadster. The car ran fine and the windows etc worked but the spoiler and roof didn't work.

 

Here is a photo of my original Bcm.
You need more than just a match for the Part number at the top staring with the A. From what I've figured out you also need to match the number beside the Temic and the HW and SW need to match, I assume that's the hardware and software numbers. And also match the number with the W in it.
The one that I currently have in is an exact match to everything except for the 03W38, the one I have in I believe is a 03W42 and it still isn't the right one, so know I bought one with an identical match to everything.. We will see how that works out.

So are you looking to put a retractable spoiler on your srt? If so I don't think that I would mess with your Bcm as it may cause you a bunch of other issues software wise.. Perhaps have it manually retract with a switch or figure a way to have it deploy during certain speed conditions etc.. Using another external controller or Plc ( programable logic controller) using ladder logic that you can easily program and work it out that way without using any of the cars systems.

 

Forgot to add the pic in the previous post

 

Hello MM04, I know this is an old post but I'm chasing an issue with my car and it seems it's coming from the BCM. I've seen posts here about replacing the BCM and how the numbers should match but I do not see anything that specifies what the numbers on the BCM mean. I found a used BCM which has all the same numbers except for the last 5 on the TEMIC. Mine is 04W06 and the replacement one is 03W40, everything else matches.

How did your BCMreplacement work out?

FYI my BCM numbers are as follows:

A193 820 00 26 [01]
TEMIC 00005357 04W06
HW:46/02 SW:27/03

Hopefully you still look at the forum and have some insight for me and others.

Thanks!

 

That’s the oil grade it uses………😉
Could that be the date it was made in some form?

 

Heya OH80 good to hear from you.
Hehe...I've considered dates but in the various BCMs I've looked at I've seen numbers higher than 30 in this group of numbers so but I'm not sure it means a date. I just can't seem to find any references anywhere that define what those numbers actually mean. I'll keep looking. I bought the bcm anyway for $60 bucks (they've dropped in price since last year) I'll post up if it works.

[update] My XF's build date is March '04 so that doesn't match the numbers on my BCM.
Hope you're well my friend. Cheers.

 

Hello Dave,
Parts suppliers use the week number and year to indicate the date parts were made. Example HW: 52/03 for the last week of 2003. In this example the part should be found installed on a 2004 or 2005 model year car manufactured in 2004 calendar year.
I'm also thinking that HW could be referencing hardware built date and SW for software release date.
IMO the BCM (Hardware) is the same. The only difference is the way they are programmed or reprogrammed, for example power operated or fixed spoiler, Auto or Manual Transmission, Fog lights or not DRL and other difference between Base, Limited and SRT and regulations in different parts of the world..
I hope all is well with you and the XF.

 

Heya MI!
Ah, ok that makes sense. As I said my car was built in March of 04 and those were the only numbers that don't match the BCM I found on eBay. It will be here on Friday so we'll know if it solves the issue then.

So good to hear from you otherwise! All is good here, I moved a couple of years back away from the DC area to Delaware (farm country). Loving the next to zero traffic
I'm slowly replacing parts on the XF as needed, but otherwise, she's in good shape. I replaced the steering damper this weekend that tightened things up a bit and the little plastic clip that attached to the oil filter housing on the engine. Broke off when replacing the serpentine belt. Got both the Damper and Clip from Needswings (glad they still have some XF parts inventory).
Cheers and thanks for the info!

 

I’ve cloned my NA roadster into an SRT
I removed the speed deployed spoiler and swapped with a fixed wing

Initially retained original NA BCM. windows worked and top went down everything was fine go for a spin and All good. But when it came time to put the roof back up

press the top button and Beep beep beep was all that happened.
had to turn off car, restart and then could cycle the roof back up

I looked into the switch limiters and just couldn’t work it out.

In the event I need something in the future I had purchased a spare set of electronic from a wrecked SRT roadster.
ecu
bcm
skreem
ring
keys etc

Went to the part stash, dug out the BCM from the SRT and replaced my existing NA BCM

took me 5-10 min. Reconnected the battery and gave it a try. Problem fixed, top goes up and down and not waiting for a signal from a spoiler that’s been removed.

no programming required

I believe that there are 4 different BCM
2 - NA roadster and coupe
2 - SRT roadster and coupe

The 04 and SE models might also be different
