The Evolution Of Diagnostic Equipment

Simply has BMW electrical architecture changed over the last decade, but so gets equipment to service all of. The equipment has changed, the interfaces have changed additionally the complexity of setup and use.

Early tools

Back in the 1990's, the Group Tester One (GT1) was introduced. Had been a few versions, like DIS Plus (stationary setup), however the GT1 is essentially the most common and precisely what will be referenced here. The GT1 is a portable device which contained a rechargeable battery. It has a touchscreen technology for easy gain the benefits of. It contained software for Diagnosing and also had software called TIS (Technical Information Display) which could be the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So from the same tool, you could Diagnose the problem, look up the best way to replace the component and then perform needed initializations for your new part. Two interfaces were used: EDIC (yellow interface) and the OPS (orange interface). Later versions of the OPS were called OPPS, since they carried additional diagnostics for the Byteflite system and these were also yellow, but much bigger as compared to the EDIC. Authentic GT1s are on the portable touchscreen piece. There are many "cloned" units out there, adapted to have a PC. Either genuine or cloned, the interfaces work the same and fasten via an Ethernet port.

Later versions of your GT1 software removed CIP, and moved it to other computer (for storage), but still accessible from the GT1. This new software was called Progman (short for Program Manager). This new software contained each of the CIP functions and added extra features like multiple car programming and dual channel programming for every car (DIAGBUS and most bus simultaneously).

Third Generation equipment

Fast to about 2008 when 3rd Generation (3G) of equipment was released: ISIS. The contents of ISIS are so large, that dedicated servers are installed at the card dealer. An online version is for purchase to the aftermarket with regard to fee, called OSS. It might probably be discovered at BMW's tech website. With the introduction of ISIS comes a new interface, called ICOM. Previous interfaces (EDIC & OPS) won't along with ISIS. ISIS consists of a few parts, since it entirely replaced GT1 & Progman. The main part of ISIS with regard to used as shop referred to as "ISTA", may be further broken on to two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.


GT1s could be found such as anywhere, including eBay lengthy cheap. BMW realized how the tool was easily cloned and sold worldwide. Many levels of security have been put into the creation of ISIS to stop this, in both resident servers and online versions. This makes it harder for non-dealer shops perform on the newer toys. One would think that since the GT1 was discontinued in 2009, you may just keep using that for several more years until the newer system became more available, however, BMW stayed one step ahead! Whenever a car is programmed i'm able to new ISTA/P, it upgrades the software beyond stage of what Program can recognize. That means, once a car has been updated with ISTA/P, you can NEVER use Progman on the griddle again, rendering the "cloned" versions useless on that car. Also, when a module is installed, computer software that is pre-installed on that module is also newer than Program can recognize, which stop total programming process, forcing the vehicle to be programmed by ISTA/P.

So can that mean for the BMW person? As a response to the newer systems, many BMW owners can extended repair scenario themselves. Many aftermarket shops are also sending folks to dealerships as an outcome. However, not every aftermarket shops have fallen behind. There are a bunch a limited number of of BMW specialty shops that continue to top of manufacturer technology, so that no car is turned away! When interested in a place to service your BMW, confident that they can carry out ALL associated with repair, including Diagnostics and CIP!
