Not really has BMW electrical architecture changed over the last decade, but so comes with the equipment to service the whole bunch. The equipment has changed, the interfaces have changed and also the complexity of setup and use.

Early tools

Back in the 1990's, the Group Tester One (GT1) was introduced. Have been a few versions, like DIS Plus (stationary setup), explain to you GT1 is one of the most common and just what will be referenced here. The GT1 is a portable device which contained a rechargeable wide variety. It has a touchscreen display for easy employ. It contained software for Diagnosing and also had software called TIS (Technical Information Display) which may 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 ways 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 people also yellow, but much bigger compared to a EDIC. Authentic GT1s are on the portable touchscreen element. There are many "cloned" units out there, adapted to look at 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 a separate 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 every single car (DIAGBUS and most bus simultaneously).

Third Generation equipment

Fast toward about 2008 when 3rd workout Generation (3G) of equipment was released: ISIS. The contents of ISIS are so large, that dedicated servers are installed at the casino dealer. An online version is for sale to the aftermarket to put together a fee, called OSS. It may well be purchased at BMW's tech website. Using the introduction of ISIS comes a new interface, called ICOM. Previous interfaces (EDIC & OPS) won't use ISIS. ISIS consists of just a few parts, since it entirely replaced GT1 & Progman. The main part of ISIS will be used as shop is named a "ISTA", which be further broken into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s could be found essential because of anywhere, including eBay for very cheap. BMW realized how the tool was easily cloned and sold worldwide. Many levels of security tend to be put in the creation of ISIS to prevent this, inside resident servers and online versions. This is it harder for non-dealer shops function with on the newer cars. One would find that since the GT1 was discontinued in 2009, others just keep using that for several more years until the newer system became more available, however, BMW stayed one step ahead! In case 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 may be updated with ISTA/P, may do NEVER use Progman on it again, rendering the "cloned" versions useless on that exact car. Also, when a module is installed, the software that is pre-installed on that module is also newer than Program can recognize, may stop total programming process, forcing the car to be programmed by ISTA/P.

So what does that mean for the BMW person? As a result of the newer systems, many BMW owners can a lot more repair the cars themselves. Many aftermarket shops are also sending folks to dealerships as an outcome. However, not every aftermarket shops have fallen behind. Number of obvious a limited number of BMW specialty shops that adhere to top of manufacturer technology, so that no car is turned away! When looking for a place to service your BMW, certain that you they can carry out ALL regarding repair, including Diagnostics and CIP!
