Not simply has BMW electrical architecture changed throughout the last decade, but so gets the equipment to service them. The apparatus changed, the interfaces have changed plus the complexity of setup and employ.

Early tools

During the 1990’s, the viewers Tester One (GT1) was introduced. There was a couple of versions, like DIS Plus (stationary setup), even so the GT1 is the most common and is what is going to be referenced here. The GT1 is often a portable device which contained a chargeable battery. It possesses a touchscreen technology for simple use. It contained software for Diagnosing and in addition 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 can Diagnose the problem, search for the way to switch the component and then perform the needed initializations for that new part. Two interfaces were utilised: EDIC (yellow interface) and the OPS (orange interface). Later versions in the OPS were called OPPS, simply because they carried additional diagnostics for that Byteflite system plus they were also yellow, but larger than the EDIC. Authentic GT1s take presctiption the portable touchscreen unit. There are several “cloned” units out there, adapted to function with a PC. Either genuine or cloned, the interfaces work exactly the same and fasten by using an Ethernet port.

Later versions in the GT1 software removed CIP, and moved it into 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 all the CIP functions and added new features like multiple car programming and dual channel programming for every car (DIAGBUS and many bus simultaneously).

Third Generation equipment

Fast forward to about 2008 when the Third Generation (3G) of apparatus was published: ISIS. The items in ISIS are very large, that dedicated servers are set up on the dealership. A web-based version is accessible towards the aftermarket for a fee, called OSS. It is usually bmw navigation package. 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, mainly because it completely replaced GT1 & Progman. The main section of ISIS which is used inside the shop is termed “ISTA”, which may be further categorised into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s are available anywhere you want to, including eBay for really cheap. BMW seen that the tool was easily cloned and sold worldwide. Many amounts of security are already placed into the development of ISIS to avoid this, in resident servers and online versions. This will make it much harder for non-dealer shops to function about the newer cars. One could believe that since GT1 was discontinued in ’09, you can keep by using their for a lot of more years before the 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 program after dark degree of what Program can recognize. This means, when a car continues to be updated with ISTA/P, you cant ever use Progman on it again, rendering the “cloned” versions useless on that particular car. Also, whenever a new module is installed, the program that’s pre-installed on that module is also newer compared to what Program can recognize, that may pun intended, the entire programming process, forcing the auto to be programmed by ISTA/P.

Just what exactly does which means that for that BMW owner? Due to the newer systems, many BMW owners can no longer repair the cars themselves. Many aftermarket shops may also be sending the cars to dealerships because of this. However, not all aftermarket shops have fallen behind. There are a small selection of of BMW specialty shops that stick to the surface of manufacturer technology, to ensure that no car is averted! When looking for a place to service your BMW, make sure they’re able to do ALL aspects of repair, including Diagnostics and CIP!
