BMW Service Technology – The Progression of Diagnostic Tools

Not simply has BMW electrical architecture changed over the past decade, but so has got the equipment to service them. The gear changed, the interfaces have changed plus the complexity of setup and employ.

Early tools

In the 1990’s, the Group Tester One (GT1) was introduced. There are a number of versions, like DIS Plus (stationary setup), nevertheless the GT1 is easily the most common and is also what will be referenced here. The GT1 can be a portable device which contained a chargeable battery. It provides a touchscreen technology for easy use. It contained software for Diagnosing as well as had software called TIS (Technical Information Display) the actual Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So from your same tool, you might Diagnose the situation, lookup the way to switch the component and after that do the needed initializations to the new part. Two interfaces were utilised: EDIC (yellow interface) as well as the OPS (orange interface). Later versions with the OPS were called OPPS, because they carried additional diagnostics to the Byteflite system and so they were also yellow, but much wider than the EDIC. Authentic GT1s are saved to the portable touchscreen unit. There are several “cloned” units around, adapted to work with a PC. Either genuine or cloned, the interfaces work the same and repair through an Ethernet port.

Later versions with the GT1 software removed CIP, and moved it into a separate computer (for storage), but still accessible from your GT1. This new software was called Progman (short for Program Manager). This new software contained each of the CIP functions and added extra features like multiple car programming and dual channel programming for each car (DIAGBUS and a lot bus simultaneously).

Third Generation equipment

Skip ahead to around 2008 once the Third Generation (3G) of it technology premiered: ISIS. The valuables in ISIS are so large, that hosting are set up at the dealership. An online version is available on the aftermarket for a small charge, called OSS. It is usually bmw sport gearbox. Using the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS has a few parts, because it completely replaced GT1 & Progman. The main a part of ISIS that is used inside the shop is termed “ISTA”, which is often further divided into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s is found just about anywhere, including eBay for really cheap. BMW remarked that the tool was easily cloned and sold worldwide. Many degrees of security have been put in the growth of ISIS in order to avoid this, both in resident servers and internet-based versions. This makes it much harder for non-dealer shops to work for the newer cars. You are likely to feel that since the GT1 was discontinued in ’09, you might just keep using that for many more years before the newer system became more available, however, BMW stayed a pace ahead! Every time a car is programmed together with the new ISTA/P, it upgrades the program past the a higher level what Program can recognize. This means, once a car has become updated with ISTA/P, you’ll never use Progman on it again, rendering the “cloned” versions useless on that particular car. Also, whenever a new module is installed, the program that is certainly pre-installed on that module can be newer compared to what Program can recognize, which can stay away from the entire programming process, forcing the car to get programmed by ISTA/P.

What exactly does which means that to the BMW owner? Due to the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships as a result. However, not every aftermarket shops have fallen behind. There’s a limited number of BMW specialty shops that stick to surface of manufacturer technology, so that no car is turned away! When searching for a place to service your BMW, make sure they are able to do ALL aspects of repair, including Diagnostics and CIP!
