Not just has BMW electrical architecture changed over the past decade, but so gets the equipment to service them. The equipment changed, the interfaces have changed along with the complexity of setup and make use of.

Early tools

Within the 1990’s, the audience Tester One (GT1) was introduced. There are a few versions, like DIS Plus (stationary setup), even so the GT1 is regarded as the common and it is what is going to be referenced here. The GT1 is a portable device which contained a rechargeable battery. It possesses a touchscreen technology for simple use. It contained software for Diagnosing and in addition 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 from your same tool, you may Diagnose the situation, search for how to replace the component after which perform the needed initializations to the new part. Two interfaces were utilised: EDIC (yellow interface) along with the OPS (orange interface). Later versions of the OPS were called OPPS, simply because they carried additional diagnostics to the Byteflite system and so they were also yellow, but much larger than the EDIC. Authentic GT1s are saved to the portable touchscreen unit. There are numerous “cloned” units on the market, adapted to be effective over a PC. Either genuine or cloned, the interfaces work precisely the same and fasten with an Ethernet port.

Later versions of the GT1 software removed CIP, and moved it with a separate computer (for storage), but nonetheless accessible from your 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 each car (DIAGBUS and a lot bus simultaneously).

Third Generation equipment

Go forward to around 2008 if the Third Generation (3G) of apparatus was published: ISIS. The contents of ISIS are so large, that server colocation are installed in the dealership. A web-based version can be obtained on the aftermarket for their fee, called OSS. It can be bmw m steering. With the introduction of ISIS comes a brand new interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS includes a few parts, mainly because it completely replaced GT1 & Progman. The principle part of ISIS utilized from the shop is known as “ISTA”, which may be further broken down into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s are available just about anywhere, including eBay for cheap. BMW realized that the tool was easily cloned and sold worldwide. Many numbers of security have been placed into the development of ISIS to stop this, both in resident servers and internet-based versions. Labeling will help you more difficult for non-dealer shops to be effective on the newer cars. One would believe that since GT1 was discontinued last year, you may just keep using that for many more years before newer system became more available, however, BMW stayed a pace ahead! Each time a car is programmed with the new ISTA/P, it upgrades the application after dark amount of what Program can recognize. Which means, each car has become updated with ISTA/P, you may never use Progman about it again, rendering the “cloned” versions useless on that particular car. Also, every time a new module is installed, the application that’s pre-installed on that module can also be newer when compared with Program can recognize, that may pun intended, the entire programming process, forcing the auto being programmed by ISTA/P.

What exactly does that mean to the BMW owner? As a result of the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships because of this. However, its not all aftermarket shops have fallen behind. There is a small number of of BMW specialty shops that stick to top of manufacturer technology, to ensure no car is beaten down! While searching for a location to service your BMW, ensure they’re able to do ALL aspects of repair, including Diagnostics and CIP!
