Not simply has BMW electrical architecture changed over the last decade, but so has the equipment to service them. The device has changed, the interfaces have changed as well as the complexity of setup and rehearse.
Early tools
In the 1990’s, the Group Tester One (GT1) was introduced. There was a couple of versions, like DIS Plus (stationary setup), nevertheless the GT1 is the most common which is after that be referenced here. The GT1 is really a portable device which contained a chargeable battery. It provides a touchscreen technology for easy use. It contained software for Diagnosing and also had software called TIS (Technical Information Display) which is Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So in the same tool, you can Diagnose the problem, research the best way to replace the component after which perform the needed initializations for that new part. Two interfaces were utilized: EDIC (yellow interface) as well as the OPS (orange interface). Later versions from the OPS were called OPPS, because they carried additional diagnostics for that Byteflite system and they were also yellow, but larger as opposed to EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are several “cloned” units available, adapted to be effective on the PC. Either genuine or cloned, the interfaces work precisely the same and correct through an Ethernet port.
Later versions from the GT1 software removed CIP, and moved it to a separate computer (for storage), but nonetheless accessible in the GT1. This new software was called Progman (short for Program Manager). This new software contained all of the CIP functions and added new features like multiple car programming and dual channel programming for each car (DIAGBUS and quite a few bus simultaneously).
Third Generation equipment
Fast forward to around 2008 in the event the Third Generation (3G) of kit was published: ISIS. The items in ISIS are so large, that server colocation are installed in the dealership. An internet version can be acquired towards the aftermarket for their fee, called OSS. It is usually top 10 bmw videos. With all the introduction of ISIS comes a whole new interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS has a few parts, mainly because it completely replaced GT1 & Progman. The key section of ISIS which is used inside the shop is termed “ISTA”, which can be further separated into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s can be found just about anywhere, including eBay for very cheap. BMW remarked that the tool was easily cloned and sold worldwide. Many degrees of security have been put in the development of ISIS to avoid this, in both resident servers and internet-based versions. This makes it harder for non-dealer shops to be effective on the newer cars. You are likely to feel that considering that the GT1 was discontinued during 2009, you can keep using that for many more years before the newer system became more available, however, BMW stayed one step ahead! Whenever a car is programmed with the new ISTA/P, it upgrades the program after dark degree of what Program can recognize. Which means, when a car may be updated with ISTA/P, you may never use Progman on it again, rendering the “cloned” versions useless with that particular car. Also, when a new module is installed, the program that’s pre-installed with that module can be newer than what Program can recognize, which could pun intended, the entire programming process, forcing the vehicle being programmed by ISTA/P.
What exactly does this mean for that BMW owner? As a result of the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops are also sending the cars to dealerships consequently. However, don’t assume all aftermarket shops have fallen behind. There is a small number of of BMW specialty shops that stay with surface of manufacturer technology, to ensure that no car is rejected! While searching for an area to service your BMW, make sure they are able to do ALL aspects of repair, including Diagnostics and CIP!
