Not simply has BMW electrical architecture changed over the last decade, but so has the equipment to service them. The device is different, the interfaces have changed plus the complexity of setup and make use of.
Early tools
Within the 1990’s, the Group Tester One (GT1) was introduced. There were a couple of versions, like DIS Plus (stationary setup), however the GT1 is regarded as the common and it is after that be referenced here. The GT1 can be a portable device which contained a chargeable battery. It has a touchscreen technology for quick use. It contained software for Diagnosing as well as had software called TIS (Technical Information Display) the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So from your same tool, you can Diagnose the problem, research how to switch the component after which carry out the needed initializations for the new part. Two interfaces were chosen: EDIC (yellow interface) along with the OPS (orange interface). Later versions in the OPS were called OPPS, since they carried additional diagnostics for the Byteflite system and they also were also yellow, but much bigger as opposed to EDIC. Authentic GT1s are saved to the portable touchscreen unit. There are numerous “cloned” units around, adapted to function on the PC. Either genuine or cloned, the interfaces work precisely the same and connect via an Ethernet port.
Later versions in the GT1 software removed CIP, and moved it to a separate computer (for storage), but nevertheless accessible from your GT1. This new software was called Progman (short for Program Manager). This new software contained every one of the CIP functions and added new features like multiple car programming and dual channel programming for each car (DIAGBUS and MOST bus simultaneously).
Third Generation equipment
Skip forward to about 2008 if the Third Generation (3G) of it technology premiered: ISIS. The valuables in ISIS are so large, that dedicated servers are set up in the dealership. An online version can be acquired on the aftermarket for a small charge, called OSS. It may be bmw ista. Together with the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS is made up of few parts, as it completely replaced GT1 & Progman. The main a part of ISIS utilized inside the shop is called “ISTA”, that may be further separated 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 very cheap. BMW seen that the tool was easily cloned and sold worldwide. Many amounts of security have already been put in the creation of ISIS to avoid this, both in resident servers and internet based versions. It is then much harder for non-dealer shops to function about the newer cars. You are likely to feel that since GT1 was discontinued in ’09, you can keep by using their for several more years before newer system became more available, however, BMW stayed a stride ahead! Every time a car is programmed with all the new ISTA/P, it upgrades the software program beyond the level of what Program can recognize. That means, each car continues to be updated with ISTA/P, you can NEVER use Progman onto it again, rendering the “cloned” versions useless on that particular car. Also, every time a new module is installed, the software program that is certainly pre-installed on that module is additionally newer when compared with Program can recognize, which can stay away from the entire programming process, forcing the vehicle to be programmed by ISTA/P.
Just what exactly does that mean for the BMW owner? On account of the newer systems, many BMW owners still can’t repair the cars themselves. Many aftermarket shops may also be sending the cars to dealerships because of this. However, don’t assume all aftermarket shops have fallen behind. There are a small selection of of BMW specialty shops that stay with top of manufacturer technology, so that no car is averted! While searching for a spot to service your BMW, make certain they can do Every aspect of repair, including Diagnostics and CIP!
