Not merely has BMW electrical architecture changed during the last decade, but so has the equipment to service them. The device has evolved, the interfaces have changed as well as the complexity of setup and make use of.

Early tools

In the 1990’s, the audience Tester One (GT1) was introduced. There are several versions, like DIS Plus (stationary setup), however the GT1 is among the most common and is also what will be referenced here. The GT1 can be a portable device which contained a rechargeable battery. It provides a touchscreen display screen for quick 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 from the same tool, you could Diagnose the situation, lookup how to switch the component then perform the needed initializations for that new part. Two interfaces were utilised: EDIC (yellow interface) along with the OPS (orange interface). Later versions with the OPS were called OPPS, simply because they carried additional diagnostics for that Byteflite system and so they were also yellow, but much wider compared to EDIC. Authentic GT1s are on the portable touchscreen unit. There are several “cloned” units available, adapted to function on the PC. Either genuine or cloned, the interfaces work the identical and connect via an Ethernet port.

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

Third Generation equipment

Fast forward to around 2008 if the Third Generation (3G) of kit was published: ISIS. The valuables in ISIS are very large, that web site hosting are installed on the dealership. A web-based version can be obtained for the aftermarket for their fee, called OSS. It may be code bmw m logo. Using the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS includes a few parts, mainly because it completely replaced GT1 & Progman. The key portion of ISIS which is used within the shop is termed “ISTA”, which is often further categorised into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s is found anywhere you want to, including eBay for very cheap. BMW realized that the tool was easily cloned and sold worldwide. Many amounts of security happen to be place into the growth of ISIS in order to avoid this, in both resident servers an internet-based versions. This will make it more difficult for non-dealer shops to function for the newer cars. One could think that since the GT1 was discontinued in ’09, you could keep using that for a number of more years prior to the newer system became more available, however, BMW stayed a pace ahead! Whenever a car is programmed with all the new ISTA/P, it upgrades the program after dark amount of what Program can recognize. Which means, when a car may be updated with ISTA/P, you cant ever use Progman into it again, rendering the “cloned” versions useless with that particular car. Also, when a new module is installed, the program that’s pre-installed with that module can also be newer than Program can recognize, which may stop the entire programming process, forcing the automobile 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 will also be sending the cars to dealerships therefore. However, not every aftermarket shops have fallen behind. There’s a limited number of BMW specialty shops that stick to the top of manufacturer technology, in order that no car is rejected! While searching for a place to service your BMW, be sure they could do ALL aspects of repair, including Diagnostics and CIP!
