Not simply has BMW electrical architecture changed throughout the last decade, but so gets the equipment to service them. The apparatus has changed, the interfaces have changed along with the complexity of setup and rehearse.
Early tools
Back in the 1990’s, the Group Tester One (GT1) was introduced. There are a few versions, like DIS Plus (stationary setup), nevertheless the GT1 is easily the most common and it is what will be referenced here. The GT1 is a portable device which contained a rechargeable battery. It provides a touchscreen technology for simple use. It contained software for Diagnosing plus had software called TIS (Technical Information Display) the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So through the same tool, you could Diagnose the problem, research the best way to replace the component after which perform the needed initializations to the new part. Two interfaces were utilized: EDIC (yellow interface) along with the OPS (orange interface). Later versions with the OPS were called OPPS, given that they carried additional diagnostics to the Byteflite system and they also were also yellow, but much wider than the EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are several “cloned” units around, adapted to function on the PC. Either genuine or cloned, the interfaces work precisely the same and correct with an Ethernet port.
Later versions with the GT1 software removed CIP, and moved it to a separate computer (for storage), but nonetheless accessible through the 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 every car (DIAGBUS and quite a few bus simultaneously).
Third Generation equipment
Fast forward to around 2008 when the Third Generation (3G) of equipment premiered: ISIS. The valuables in ISIS are very large, that web site hosting are installed at the dealership. A web based version can be acquired on the aftermarket for a small charge, called OSS. It could be top 10 bmw videos. With the introduction of ISIS comes a new 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 primary part of ISIS that is used in the shop is known as “ISTA”, that may be further separated into two parts: 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 amounts of security have been placed into the creation of ISIS to prevent this, in both resident servers and online versions. Labeling will help you more difficult for non-dealer shops to function about the newer cars. One would believe that since GT1 was discontinued in 2009, you could keep by using their for many more years before the 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 beyond the level of what Program can recognize. This means, after a car has been updated with ISTA/P, you can NEVER use Progman onto it again, rendering the “cloned” versions useless with that particular car. Also, each time a new module is installed, the application which is pre-installed with that module is also newer when compared with Program can recognize, which could steer clear of the entire programming process, forcing the auto to get programmed by ISTA/P.
Precisely what does this mean to the BMW owner? On account of the newer systems, many BMW owners still can’t repair the cars themselves. Many aftermarket shops can also be sending the cars to dealerships because of this. However, not all aftermarket shops have fallen behind. You can find a select few of BMW specialty shops that remain on top of manufacturer technology, to ensure no car is rejected! When looking for a place to service your BMW, make certain they can do Every aspect of repair, including Diagnostics and CIP!
