Not merely has BMW electrical architecture changed during the last decade, but so contains the equipment to service them. The apparatus has evolved, the interfaces have changed plus the complexity of setup and employ.
Early tools
In the 1990’s, the viewers Tester One (GT1) was introduced. There were a couple of versions, like DIS Plus (stationary setup), even so the GT1 is easily the most common and it is what’s going to be referenced here. The GT1 is often a portable device which contained a chargeable battery. It provides a touchscreen technology for simple use. It contained software for Diagnosing as well as had software called TIS (Technical Information Display) which is the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So from the same tool, you could Diagnose the situation, look up the best way to switch the component after which do the needed initializations for that new part. Two interfaces were utilised: EDIC (yellow interface) and also the OPS (orange interface). Later versions in the OPS were called OPPS, given that they carried additional diagnostics for that Byteflite system plus they were also yellow, but much bigger as opposed to EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are lots of “cloned” units on the market, adapted to function on a PC. Either genuine or cloned, the interfaces work precisely the same and fasten through an Ethernet port.
Later versions in the GT1 software removed CIP, and moved it to some separate computer (for storage), however accessible from 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 quite a few bus simultaneously).
Third Generation equipment
Skip forward to around 2008 when the Third Generation (3G) of apparatus was published: ISIS. The items in ISIS are so large, that server colocation are set up in the dealership. A web-based version can be acquired for the aftermarket for a small fee, called OSS. It may be bmw kombi coding. Together with the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS has a few parts, since it completely replaced GT1 & Progman. The key a part of ISIS utilized in the shop is termed “ISTA”, which is often further separated into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s is found almost anyplace, including eBay for very cheap. BMW pointed out that the tool was easily cloned and sold worldwide. Many degrees of security are already placed into the growth of ISIS to stop this, in the resident servers and internet-based versions. This makes it harder for non-dealer shops to function on the newer cars. You might believe that because the GT1 was discontinued in 2009, you could keep using for a lot of more years before the newer system became more available, however, BMW stayed a measure ahead! When a car is programmed together with the new ISTA/P, it upgrades the application after dark a higher level what Program can recognize. Meaning, after a car continues to be updated with ISTA/P, you cant ever use Progman on it again, rendering the “cloned” versions useless with that particular car. Also, every time a new module is installed, the application that is pre-installed with that module is additionally newer than what Program can recognize, which may stay away from the entire programming process, forcing the auto to get programmed by ISTA/P.
So what does that mean for that BMW owner? Because of the newer systems, many BMW owners still can’t repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships consequently. However, not all aftermarket shops have fallen behind. There is a small number of of BMW specialty shops that stay with top of manufacturer technology, to ensure no car is turned away! When searching for a place to service your BMW, make certain they could do ALL aspects of repair, including Diagnostics and CIP!
