BMW The Evolution of Diagnostic Equipment
Has BMW electrical architecture altered over the last decade, but so has got the gear to service them. The equipment has changed, the interfaces have changed and additionally the complexity of use and set up. In the 1990's, the Group Tester One (GT1) was introduced. There were a few versions, like DIS Plus (stationary set up), yet the GT1 is the most common and is what will probably be referenced here. The GT1 is a portable device which comprised a battery that is rechargeable. It has a touchscreen display for simple use. Early versions of Diagnostics also included applications called Coding, Programming & Individualization (CIP). So from exactly the same tool, you look up the best way to replace the component can Diagnose the issue and perform the needed initializations for the new part. Two interfaces were used: EDIC (yellow interface) as well as the OPS (orange interface). After variants of the OPS were called OPPS, since they carried added diagnostics and they were also yellowish, but much bigger compared to EDIC. Legitimate GT1s are about the portable touchscreen unit. There are many "cloned" units out there, adapted to work on a PC. Either genuine or cloned, the interfaces work the same and connect via an Ethernet port.
 Later versions of the GT1 applications removed CIP, and moved it to another computer (for storage), but still reachable from the GT1. This new applications was called Progman (brief for Program Manager). This new software featured all of the CIP functions and added new features like multiple car programming and double station programming for each automobile (DIAGBUS and MOST bus concurrently). The contents of ISIS are not so small, that dedicated servers are installed in the car dealer. A web-based version is available to the aftermarket to get fee. It are available at BMW's technology site. Together with the introduction of ISIS comes a brand new interface. Previous interfaces (EDIC & OPS) won't operate with ISIS. Since it entirely replaced GT1 & Progman ISIS consists of a few parts. The key part of ISIS that is used in the store is named "ISTA", which can be further broken down into two components: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
 GT1s could be located just about anywhere, including eBay for really economical. New Era of BMW Diesel Engine Features  realized the tool was readily cloned and sold worldwide. Many rates of security have been put in the creation of ISIS to prevent this, in online versions and both resident servers. This makes it considerably more challenging for non-dealer shops to work on the more recent cars. Whenever a car is programmed with the ISTA/P that is newest, it upgrades the program beyond the level of what Program can recognize. That means, once a car has been upgraded with ISTA/P, you can NEVER use Progman on it again, rendering the "cloned" versions useless on that special car. Also, when a new module is installed, the software that's pre-installed on that module can also be not older than what Program can recognize, which can stop the whole programming procedure, driving the car to be programmed by ISTA/P.
 So what does that mean for the BMW owner? As a result of the newer systems, many BMW owners can no longer repair the cars themselves. Many aftermarket stores are also sending the cars to dealerships as a result. However, not all aftermarket stores have fallen behind. There are a select few of BMW specialty shops that stay on top of manufacturer technology, to ensure no car is turned away! Make sure they can do ALL aspects of repair, including CIP and Diagnostics when buying place to service your BMW!
