Not only has BMW electrical architecture changed throughout the last decade, but so contains the equipment to service them. The apparatus is different, the interfaces have changed along with the complexity of setup and use.
Early tools
In the 1990’s, the audience Tester One (GT1) was introduced. There was a couple of versions, like DIS Plus (stationary setup), though the GT1 is among the most common which is after that be referenced here. The GT1 is often a portable device which contained a rechargeable battery. It provides a touchscreen display screen for easy use. It contained software for Diagnosing plus had software called TIS (Technical Information Display) the actual Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So through the same tool, you could Diagnose the challenge, search for the best way to replace the component and after that carry out the needed initializations to the new part. Two interfaces were utilized: EDIC (yellow interface) and the OPS (orange interface). Later versions in the OPS were called OPPS, simply because they carried additional diagnostics to the Byteflite system plus they were also yellow, but larger than the EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are numerous “cloned” units available, adapted to function on a PC. Either genuine or cloned, the interfaces work precisely the same and connect through an Ethernet port.
Later versions in the GT1 software removed CIP, and moved it into a separate computer (for storage), but still accessible through the GT1. This new software was called Progman (short for Program Manager). This new software contained all of the CIP functions and added new features like multiple car programming and dual channel programming per car (DIAGBUS and a lot bus simultaneously).
Third Generation equipment
Go forward to about 2008 when the Third Generation (3G) of kit was published: ISIS. The valuables in ISIS are really large, that web site hosting are installed with the dealership. An online version can be acquired on the aftermarket for their fee, called OSS. It could be bmw acceleration video. With all the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS is made up of few parts, since it completely replaced GT1 & Progman. The key part of ISIS utilized in the shop is termed “ISTA”, that may be further broken down into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s is available just about anyplace, including eBay for really cheap. BMW remarked that the tool was easily cloned and sold worldwide. Many amounts of security have already been placed into the creation of ISIS to avoid this, in the resident servers and internet based versions. This makes it more difficult for non-dealer shops to function about the newer cars. One could believe that since the GT1 was discontinued in 2009, you could just keep using for several more years before newer system became more available, however, BMW stayed a stride ahead! Every time a car is programmed together with the new ISTA/P, it upgrades the software at night a higher level what Program can recognize. Meaning, each car may be updated with ISTA/P, you’ll never use Progman into it again, rendering the “cloned” versions useless on that particular car. Also, every time a new module is installed, the software which is pre-installed on that module is also newer compared to what Program can recognize, which may pun intended, the entire programming process, forcing the vehicle to be programmed by ISTA/P.
So what does this mean to the BMW owner? Due to the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops may also be sending the cars to dealerships as a result. However, not every aftermarket shops have fallen behind. There is a select few of BMW specialty shops that stick to the surface of manufacturer technology, to ensure that no car is rejected! When searching for a place to service your BMW, make sure they are able to do ALL aspects of repair, including Diagnostics and CIP!
