Not merely has BMW electrical architecture changed throughout the last decade, but so contains the equipment to service them. The gear has evolved, the interfaces have changed plus the complexity of setup and make use of.
Early tools
During the 1990’s, the audience Tester One (GT1) was introduced. There was a number of versions, like DIS Plus (stationary setup), nevertheless the GT1 is the most common and is also what’s going to be referenced here. The GT1 is really a portable device which contained a rechargeable battery. It features a touchscreen display for straightforward use. It contained software for Diagnosing plus 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 in the same tool, you might Diagnose the situation, look up how you can replace the component and then perform needed initializations for your new part. Two interfaces were utilized: EDIC (yellow interface) and also the OPS (orange interface). Later versions of the OPS were called OPPS, since they carried additional diagnostics for your Byteflite system plus they were also yellow, but larger as opposed to EDIC. Authentic GT1s are saved to the portable touchscreen unit. There are numerous “cloned” units around, adapted to operate on a PC. Either genuine or cloned, the interfaces work the identical and correct by using an Ethernet port.
Later versions of the GT1 software removed CIP, and moved it with a separate computer (for storage), but still accessible in the 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 per car (DIAGBUS and many bus simultaneously).
Third Generation equipment
Skip ahead to about 2008 if the Third Generation (3G) of it technology was launched: ISIS. The belongings in ISIS are very large, that server colocation are installed with the dealership. An online version can be acquired to the aftermarket for a small fee, called OSS. It is usually bmw software update. Together with the introduction of ISIS comes a whole new interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS is made up of few parts, because it completely replaced GT1 & Progman. The principle section of ISIS which is used inside the shop is termed “ISTA”, which can be further separated into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s can be found anywhere you want to, including eBay for really cheap. BMW realized that the tool was easily cloned and sold worldwide. Many degrees of security happen to be put in the creation of ISIS in order to avoid this, both in resident servers and internet-based versions. Labeling will help you more difficult for non-dealer shops to operate for the newer cars. One would believe that because the GT1 was discontinued in ’09, you might keep using for a number of more years until the newer system became more available, however, BMW stayed one step ahead! Every time a car is programmed with all the new ISTA/P, it upgrades the program beyond the level of what Program can recognize. Meaning, each car has been updated with ISTA/P, you may never use Progman on it again, rendering the “cloned” versions useless on that particular car. Also, every time a new module is installed, the program that’s pre-installed on that module is also newer than what Program can recognize, which may steer clear of the entire programming process, forcing the automobile to become programmed by ISTA/P.
Precisely what does which means that for your BMW owner? Because of the newer systems, many BMW owners still can’t repair the cars themselves. Many aftermarket shops are also sending the cars to dealerships as a result. However, don’t assume all aftermarket shops have fallen behind. You can find a select few of BMW specialty shops that remain on surface of manufacturer technology, to ensure no car is beaten down! When looking for a spot to service your BMW, make sure they are able to do ALL aspects of repair, including Diagnostics and CIP!
