Coding a secondhand Airbag ECU, can anyone help please?

[tomjonesBT33]

found this on the internet:

Step by Step to edit VIN, Flash, Code to Default, Clear Errors and Start System Time of the Airbag Gateway Module.

INPA: UIF (User Information Field) Report
1-Open INPA>select your car model (E60)>Functional Jobs>F3 UIF
2-You'll see a list of all control units with their ZUSB number and VIN
3-Print to PDF the report.
4-Identify the ZUSB numbers without your VIN and copy from the PDF and close INPA

Reopening this thread.

I too need to code the VIN in a secondhand SBSR satellite pillar module.

My car is a 2004 2.5i e85.

I'm stuck on step 1 above. I have INPA 5.0.6 and when I select car model E85, Functional Jobs is not an option like it is for some of the other models, e.g., E60, E65, etc. So I choose IDENT / read-clear error/info memory e85 instead. But then <F3> UIF is not an option, again like it is for some other models.

How can I determine the ZUSB (or Assembly Number) for my SBSR85 module?

Thanks

I did this on my car a while ago and updated the guide to make it a bit more suitable for the e85:

Hopefully that will help

Quick update. Eventually took the z4 to the dealership to see if they could code it. They couldnt and it can't be done as the chassis number cannot be overwritten on the safety ecu. £900 for a new coded safety ecu fitted at the dealer!

Don't know about 'safety' ecu, but my understanding is dealers can't overwrite anything with INPA anyway - much more profit in selling a new unit. To overwrite modules I think you need a specialist with INPA+. But I may be wrong...

I had problems as well.

I've added my experience to this one: https://z4-forum.com/forum/viewtopic.php?f=3&t=37521
So possibly read the last post, then if you feel brave, follow this thread:

Sounds like a dealer :telloff:

Well I finally got the airbag light sorted last night. Thanks to all for the replies. I agree with a previous post that it's 'weird' not seeing the airbag light on.

The write up and google doc resources provided by TomR were a HUGE help. By looking thought the .HIS files, I finally figured out that the ECU family that I needed to use was SBR264, not SBSR85 which is what shows up in INPA and ISTA. Also, it was good to confirm that the ZUSB number is actually just the part number. There are varying opinions about that, which I've read, and since the e85 doesn't have the UIF <F3> feature in INPA to provide the nice table like you see for other models, it was very confusing until reading TomR's write-up.

I want to note that in WinKFP, when performing the update, I chose 'unverbalt' (unspoiled) versus the dash ' - ' Those were my only two options. I was not sure this was the right thing to do since I replaced my original part with a used SBSR module, but it worked. So may want to clarify that part of the write-up.

Now the car is ready for safety inspection!

Regards, Tom

Good job, gld you got it working

I'm going through the same issue right now with my 2004 2.5 with the right door module 6939763. The original module was timing out and throwing an error. Replaced with a second hand module with the same number but now receive incorrect chassis number fault. I can't find 6939763 in any of the .HIS files but the main module 6939810 is in the SIM85.his file. I'm not sure how to update other than trying to find older daten files, any help would be greatly appreciated.

If you’re using the same part number it will work... you just need to access the correct module and change the Vin. Can’t speak for the process as I didn’t do it personally, although it was done on my car. What programs are you using (and maybe someone else can help). Best of luck!

 

[waynoh]

The plan was to use WinKFP but when I select comfort mode\enter ZUSB and enter the part number I get error 704, assembly identification number not found.... I do also have INPA, NCS Expert/NCS Dummy, BMW Coding Tool and Tool32. Which is the easiest to use?

Thanks for responding.

I think the guy that did mine used Tool32. I'm sure he didn't search for the part number... the module was selected from menus or a dropdown. I know the module number of mine, because I used to search for it daily on various sites. 6935920.

How about searching for the module? "Control Unit Airbag" or "Safety Information Module" those are what Real OEM refer to them as...

 

[waynoh]

Many thanks KIS, I think I'm getting close, in Tool32 I opened STVR85.prg and double clicked on c_fg_lesen to read the information on the module, on the results window I can see the invalid VIN listed next to FG_NR. I confirmed this by opening STVL85.prg and seeing my VIN in that location. Hopefully all I need to do is write out the correct VIN to the module, restart the system time and clear the errors. I'm approaching this slowly so as not to mess anything up, will let you know the outcome, I'm very optimistic!

So that didn't work, trying to write my VIN to the STVR module is resulting in the error message:

error_ecu_conditions_not_correct_or_request_sequence_error

Back for more research.....

 

[tomjonesBT33]

waynoh - I searched through my /data directory and could not find your part number in any of my .HIS files. Before I got mine working, I did scour the web looking for older software versions to gather older daten and other files. Maybe give that a try...

 

[waynoh]

Tomjones20194 - Thanks I'e been scouring for days to no avail, still looking for older files, not even sure how old I would need.

Have you tried disconnecting and re-connecting the module? If there was any sort of water damage or rust build up then maybe the contacts aren't clean?

 

[waynoh]

Tools 32 communicates with the module, it returns information with the original VIN, INPA can also clear the error from the module. Tool32 is unable to write the correct VIN to the module and WinKFP doesn't have the correct part number ion the daten file. Is there anywhere to buy the correct daten file for the car?

 

[waynoh]

I'm beginning to think it could be a configuration problem or an issue with the cable, I tried updating with WinKFP and received the following errors. Does anyone have any thoughts?

 

[kis]

Reinstall the program (or maybe all 3 programs) and take it from there?

 

[tomjonesBT33]

waynoh - does INPA work correctly?
