CAS crash whilw programming

[jsg77]

hi everyone
i have to update dme on e84 because of a dtc. with j2534 cardaq plus 2 passtru adapter and ista/p directly from bmw website. because of a ppt adapter ista/p won't let me reflashing only one module i have to update all. when i'm reprogramming CAS i receive a overvolt message on ista/p (voltage over 15v) and a fail!!! after this ista was unable to reconnect to the car. now all the car was dead nothing is working without maybe parking lights.. i have ordered inpa k+dcan interface and try to reflash cas with winkfp and after the bar was at 100% i got error with code 2086 signature check failed. if i check programmation with inpa i have status 12 for cas and 255 for jbe. now part number on cas is weird yyy***** and vin is like WAAA00000000 or something!!! at this point i don't know what to do without buying a 1500$ cas module.
any help will greatly appreciated
thank you

You don't have to buy any module. This happens. Especially with improper chargers. Especially those horrible shop things on wheels.
It's recoverable, but keep in mind that a K+DCAN has the capacity of making some modules worse.

Flash JBE first, then flash cas (with key out) and every other module that is out.
Then code whole car.

To be fair, a new CAS is only around $350, but it wouldn't solve your problem.


I think a K+DCAN should be fine for all of E84 modules, though.



(I bricked my first module with a K+DCAN.)

I haven’t try to flash jbe. do you think it’s why I always got that error? I don’t want to brick jbe to!

[328 Power 04]

The jbe is already bricked.
It will need to be recovered first before you even try to reach anything else.
It recovers fine though.

[jsg77]

Do I need to turn uif on an update vin or it’s not necessary?

[328 Power 04]

Yes, UIF should be on, just in case.

Usually you can use the update flash function for this recovery. Winkfp will retrieve previous ZUSB just fine and do the lookup to get the new ZUSB by itself.

send me cas, car will start simple as that

I have been trying to contact you. You have another PM.

[jsg77]

I have reprogram jbe and now is programming states is 1 !! But still same error while programming CAS Signatures check failed and still in programming states 12

[328 Power 04]

What interface are you using currently? What program?

[jsg77]

K +dcan INPA câble and winkfp
I update zusb in confort mode and everything went well the bar goes to 100% and after I get error

[328 Power 04]

Sounds like the k+dcan failure that I was afraid of above.


You should try to use the J2534 with winkfp. This means configuring ediabas as std:passthrud.

Fixed

To expand on this, I think this is what I would do:

Go to C:\Program Files (x86)\BMW AG\PassThruD and copy these files to C:\Ediabas\bin

Then go to C:\ProgramData\BMW AG\PassThruD and copy "PassThruD.ini" to C:\Ediabas\bin

Then go to C:\Ediabas\bin, open Ediabas.ini, and change "interface = STD:OBD" to "interface = STD:passthrud"

See if it works from there. This is assuming you've been using the same computer with the D-CAN cable and the J2534 interface

[jsg77]

My ista/p is on another computer but I can install bmw passthrud an copy other files! Since my jbe is working maybe i can buy techinfo subscriptions try to reflash CAS with ista/p j-2534???

[jsg77]

Dosen’t seems to work with J2534
Error 300
First hw interface could not be initialized!
Ifh-0018 initialisation error
😢

[jsg77]

I have retry with ista/p and it ask me to switch ignition off but key is not on switch. And after I receive a fault (the voltage at terminal 15 could not be determined)
Can I switch terminal 15 with CAS that is not working!

[TerraPhantm]

That makes me wonder if the J2534 stuff can actually detect ignition status. BMW does it a little weirdly on D-CAN cars.

[jsg77]

Since the CAS is not working the terminal 15 and 30 are on on both tools INPA with k dcan and ista/ p on another computer! And key is not on the key fob

[328 Power 04]

If you are using K+Dcan with ista/p on another computer, I assume you using the emulator? The non-paid 'standalone' ista/p isn't built to run with K+dcan, so you have to use the emulator settings to emulate ignition on and off.

Unfortunately all of this would be easier if you have an ICOM you can borrow?
You seem to have good knowledge and friends around, so maybe someone has an ICOM?

Sorry I’m not clear! I’m French person and I do the best I can to write English!! But it’s kind of worst! Ok back to real things!!! I have one computer with winkfp and k +dcan and another one with ista/p that I run on bmw website and I have to pay for. Ista is set to ptt Interface and i use J2534 cardaq plus 2 . Both software on both computer give me terminal 15 with voltage without key on fob.
I have find a person that have ICOM. We should test it today.

[328 Power 04]

Your English is perfectly fine. Probably better than my 5 years of French from school.


I understood it as you were using the pirated ISTA-P with K+DCAN on emulator.

Let us know how it turns out!

Thank you!!
Ok we have try with ICOM and it’s not working! After we have removed CAS, open it and the guy have weld wire directly on it to extract data! And he told me the eprom data is corrupted!! How this is happened! I have reflash it with web based legal version of ista/p and now the guy have to try to unbrick the eprom! Is this can be only caused by my battery charger that is rising voltage around 15v while programming?

Hello, I have the same issue on 2008 E60. I try to update the DME as per customer request. I'm using ISTA P on line and CARDAQ-M J2534. CARDAQ-M is like CARDAQ-Plus and is listed by OEM BMW ISTA website as supported device. The ISTA automatically selects CAS when programming DME and there is no way around it. It started programming CAS and halfway trough it stopped. No communication with CAS anymore. No key being recognized and no key on. Car completely dead. So, it looks like I'll need new CAS or is there a way around it ???

I'd like to add I've done the same job with the same tools on other cars and had no issues.

Please let me know!

THANK YOU!

Problem solved, I found a company that can restore these modules. Just got it back, put it in and everything is back to normal. Couldn't be happier. Here is the link if someone needs this in the future https://www.precisionecu.com/collect...e-plug-n-drive
