The Evolution Of Diagnostic Equipment

The Evolution Of Diagnostic Equipment

Not has BMW electrical architecture changed over the last decade, but so comes with the equipment to service all of. 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. There were a few versions, like DIS Plus (stationary setup), explain to you GT1 is the most common and precisely what will be referenced here. The GT1 is a portable device which contained a rechargeable wide variety. It has a touchscreen display for easy purposes. It contained software for Diagnosing and also had software called TIS (Technical Information Display) which is 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 carry out the 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 fix 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 new features like multiple car programming and dual channel programming for every car (DIAGBUS and over bus simultaneously).

Third Generation equipment

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


GT1s can be found close to anywhere, including eBay for very cheap. BMW realized how the tool was easily cloned and sold worldwide. Many levels of security are usually put in the creation of ISIS steer clear of this, inside resident servers and online versions. Abandon it much harder for non-dealer shops to work on the newer vehicles. One would think that since the GT1 was discontinued in 2009, you could just keep using that for several more years until the newer system became more available, however, BMW stayed one step ahead! Every car is programmed with the new ISTA/P, it upgrades the software beyond the of what Program can recognize. That means, really car is updated with ISTA/P, you are NEVER use Progman on the cover again, rendering the "cloned" versions useless on any particular one car. Also, when the brand new module is installed, computer software that is pre-installed on that module is also newer than what Program can recognize, that is stop the actual programming process, forcing difficulties to be programmed by ISTA/P.

So what does that mean for the BMW pet owner? As a reaction of the newer systems, many BMW owners can lengthier repair the cars themselves. Many aftermarket shops are also sending individuals to dealerships as an effect. However, not all aftermarket shops have fallen behind. Many a select few of BMW specialty shops that stay on top of manufacturer technology, so that no car is averted! When interested in a in order to service your BMW, make sure they can do ALL involving repair, including Diagnostics and CIP!
