Trying to unlock the CAS
New to bmw coding. Have Snap-On Passthru3 by DrewTechnologies. Using ISTA-P was able to access the vehicle info and see the module tree. It started to determine action plan and said below voltage. After closing session and hooking a constant power source the car is completely locked. Nothing works but the hazard lights. Still have power at the DLC but nothing else energizes. Pretty sure I bricked the CAS. Downloaded INPA. I can get ISTA to work but keeps asking for the VO. Can I connect INPA via the passthru or does it require a USB cable? Or can someone help me with the VO for the car? It's a 2008 328xi KX92479

We have had a number of people come here after bricking there car
with non BMW software. You get can get bricks with Ista P a lot of times with K/d can cable to. Start with functional jobs in Inpa and see if you can read the ECU's publish the results here. USB Cables are of no use on a e90 for programming. Everything is done though a Icom or K/D can cable hooked to the OBD. Or are you talking about a K/D can cable hooked to a PC? https://www.e90post.com/forums/showthread.php?t=1661945 https://www.e90post.com/forums/showthread.php?t=1663940 Whats a DLC Whats a passthough Everything is done through the OBD 2 connector . Also bimmergeek.net Inpa and ista D downloads are known good downloads. Last edited by ctuna; 11-30-2019 at 11:53 PM.. |

The DLC (data link connector) is the OBD2 port. A passthru is CAN enabled communication tool hooked to a PC which is basically the same as ICOM but can be used for programming virtually any brand vehicle. I was using BMW paid subscription ISTA-P provided by BMWTIS. But now that something happened and it bricked I'm trying to use INPA to read the other modules. I can't get INPA to see the car, I don't think its configured for the passthru. Came here to see if anyone knows how to link them?

Inpa will work for reading with a cheap K/D can cable .
You have to follow the setup procedures that come with the downloads to get it to work it's not plug and play. The procedures are not that difficult though. Not recommended for Ista P though some have used it. Power Supply needed for Ista P because it does the whole car and is a big battery drain. However the Bimmergeeks.net Cable and there downloads are recommended because they have a better cable and there downloads are proven to work. FRM modules are known to blow during programming no matter what you use. Not likely anybody will no how to setup that adapter You could try comparing to the parameters in the Inpa setup procedures. https://www.bimmergeeks.net/store Last edited by ctuna; 12-01-2019 at 01:32 PM.. |

When you can with ISTA are modules showing Red (not responding) or Blue (programming abort). If it's blue then you can recover them via winkfp.
Use ISTA+ by the way not ISTA/P and use a kdcan cable since your cable I think is giving you some issues |

You can use either a K/D can cable or an Icom cable for Ista D and P
but its recommended to use and Icom cable with Ista P. Some people come out OK with a K/D can cable on Ista P but it seems like kind of a toss up if it will work . Icom cable actually has memory and processor I believe. Its been noted the a K/D can cable will not program Most Bus Modules on cars made after 3/07 Cables are described in the second to last link. Most people here use the K/D can cable and are only modifying one module at a time. What were you trying to do ? Usually just updating the software in the car does not produce much in noticeable results. diagnostic manual ista/inpa https://bimmerprofs.com/diagnostics-inpa-part-1/ https://www.google.com/url?sa=t&rct=...xo19teM9vkTF-C https://www.google.com/url?sa=t&rct=...7x8H3pN8h1fMuF https://www.bimmerforums.com/forum/s...-P-actually-do https://www.google.com/url?sa=t&rct=...lkXEhlQYy4i9Nb |

You'll need to: 1) install BMW Standard tools (I gather you've done this already) 2) download BMW-specific files from the device manufacturer or search for "BMW PTT driver" 3) Install BMW PTT files in the /EDIABAS/Bin directory 4) Edit ediabas.ini to change STD:OBD to STD:Passthru (or whatever the driver software installation suggests) But honestly, there are a bunch of gotchas in that process and I would not bother. Just buy a $45 DCAN cable from www.bimmergeeks.net and be done with it. You'll be running the same set up as everyone else on this forum and everyone can help you from there. BTW, in case this is not clear to you, your passthru is not "basically the same as ICOM", the latter of which has several interfaces. ICOM-B connects through the DLC (OBDII port) like most J2534 devices and DCAN cables. ICOM-A connects through the MOST (Media Oriented Systems Transport) bus. It is often reported that ICOM-A is required to program some MOST bus modules, like the CCC/CIC. For your J2534 device, a MOST bus interface has to be purchased separately. This consideration is irrelevant to the CAS of course. EDIT: BMW-PTT is from BMW. So you need two driver sets, a device specific one from the manufacturer and one from BMW for EDIABAS. Sorry don't have a link for BMW-PTT Last edited by dpaul; 12-08-2019 at 07:36 AM.. |

Thanks for the advice and sorry for the delayed responses. My customer ended up towing it to the dealer. They told him the CAS module was bad and charged nearly $1k to replace it. Pretty certain it could have been unbricked had he given me the time. But not my car or money.

I appreciate the fact that you've provided an update - not so many bother, so props for that.
Just for the record, you're asking for trouble using ISTA-P without the interface (ICOM-A) that it expects. ISTA-P is very inflexible and its action plan likely included programming and coding a number of modules in the vehicle - you cannot confine it to a single module. The bottom line is you damaged your customer's CAS module in some way, whether it was because of a low voltage during programming, the use of ISTA-P with an inappropriate interface or some other reason. Although you feel "pretty certain" that you could have resurrected given time, with all due respect it seems clear that you do not have the experience to make such a claim or the necessary tools to deal with the fallout. I would suggest a deep dive into programming and coding (these are two different things if you were not aware) on this site. And stay away from ISTA-P |

This guy has great video's on all aspects of the car including
the best section on coding and using ista d p , Dr Gini and all the standard tools programs. I urge you to look at his video on ista p . He tells you what all the pitfalls are and even how to control ista p to do individual modules. Botton line is no ista p without icom and a stabilizing power supply. His video on Dr Gini is also very enlightening. He has many coding and DIY video's https://www.nathansbmwworkshop.com/b...or-dean-videos |
