BMW Service Technology – The Evolution of Diagnostic Equipment

Not only has BMW electrical architecture changed over the last decade, but so gets the equipment to service them. The device is different, the interfaces have changed along with the complexity of setup and use.

Early tools

Back in the 1990’s, the gang Tester One (GT1) was introduced. There was a couple of versions, like DIS Plus (stationary setup), though the GT1 is the most common which is what will be referenced here. The GT1 is a portable device which contained a rechargeable battery. It provides a touchscreen display screen for simple use. It contained software for Diagnosing and in addition 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 through the same tool, you can Diagnose the problem, research how to switch the component after which perform needed initializations for your new part. Two interfaces were utilized: EDIC (yellow interface) and also the OPS (orange interface). Later versions in the OPS were called OPPS, since they carried additional diagnostics for your Byteflite system and they were also yellow, but larger compared to the EDIC. Authentic GT1s take presctiption the portable touchscreen unit. There are numerous “cloned” units available, adapted to function on a PC. Either genuine or cloned, the interfaces work exactly the same and fasten through an Ethernet port.

Later versions in the GT1 software removed CIP, and moved it to a separate computer (for storage), but nevertheless accessible through the 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 quite a few bus simultaneously).

Third Generation equipment

Skip ahead about 2008 if the Third Generation (3G) of kit premiered: ISIS. The items in ISIS are extremely large, that dedicated servers are set up on the dealership. A web based version is available on the aftermarket for their fee, called OSS. It can be top 10 bmw videos. With the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS includes a few parts, because it completely replaced GT1 & Progman. The main portion of ISIS which is used within the shop is termed “ISTA”, which can be further divided into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s can be found just about anyplace, including eBay for inexpensive. BMW pointed out that the tool was easily cloned and sold worldwide. Many numbers of security have already been put in the development of ISIS to stop this, in both resident servers and online versions. This makes it more difficult for non-dealer shops to function for the newer cars. You are likely to think that considering that the GT1 was discontinued last year, you can keep using for a lot of more years before 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 application after dark amount of what Program can recognize. That means, once a car continues to be updated with ISTA/P, you can NEVER use Progman into it again, rendering the “cloned” versions useless with that particular car. Also, whenever a new module is installed, the application that’s pre-installed with that module is additionally newer than what Program can recognize, which can stay away from the entire programming process, forcing the car to become programmed by ISTA/P.

Just what exactly does which means that for your 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 as a result. However, its not all aftermarket shops have fallen behind. There are a small number of of BMW specialty shops that remain on the surface of manufacturer technology, in order that no car is beaten down! When searching for a location to service your BMW, ensure they can do ALL aspects of repair, including Diagnostics and CIP!
