Not only has BMW electrical architecture changed throughout the last decade, but so has the equipment to service them. The gear has changed, the interfaces have changed along with the complexity of setup and rehearse.

Early tools

During the 1990’s, the Group Tester One (GT1) was introduced. There were a few versions, like DIS Plus (stationary setup), though the GT1 is regarded as the common and is also 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 plus 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 situation, look up the best way to replace the component and after that perform the needed initializations for your new part. Two interfaces were utilized: EDIC (yellow interface) and also the OPS (orange interface). Later versions from the OPS were called OPPS, given that they carried additional diagnostics for your Byteflite system and so they were also yellow, but much wider as opposed to EDIC. Authentic GT1s are saved to the portable touchscreen unit. There are lots of “cloned” units out there, adapted to operate on a PC. Either genuine or cloned, the interfaces work exactly the same and repair with an Ethernet port.

Later versions from the GT1 software removed CIP, and moved it to 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 every one of the CIP functions and added new features like multiple car programming and dual channel programming per car (DIAGBUS and a lot bus simultaneously).

Third Generation equipment

Skip forward to around 2008 once the Third Generation (3G) of apparatus was launched: ISIS. The belongings in ISIS are extremely large, that hosting are installed on the dealership. A web-based version can be acquired towards the aftermarket for a small charge, called OSS. It may be bmw girls. With all the introduction of ISIS comes a new interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS consists of a few parts, mainly because it completely replaced GT1 & Progman. The main a part of ISIS which is used inside the shop is named “ISTA”, which may be further categorised into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s are available anywhere you want to, including eBay for inexpensive. BMW realized that the tool was easily cloned and sold worldwide. Many numbers of security are already put into the creation of ISIS to avoid this, in resident servers an internet-based versions. This makes it more difficult for non-dealer shops to operate about the newer cars. One would think that since GT1 was discontinued in 2009, you can just keep using that for several more years until the newer system became more available, however, BMW stayed one step ahead! Every time a car is programmed using the new ISTA/P, it upgrades the application past the a higher level what Program can recognize. This means, after a car continues to be updated with ISTA/P, you can NEVER use Progman about it again, rendering the “cloned” versions useless on that particular car. Also, whenever a new module is installed, the application which is pre-installed on that module can be newer than Program can recognize, which may steer clear of the entire programming process, forcing the car to get programmed by ISTA/P.

What exactly does that mean for your BMW owner? Due to the newer systems, many BMW owners still can’t 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’s a small number of of BMW specialty shops that remain on surface of manufacturer technology, to ensure no car is averted! When searching for a spot to service your BMW, ensure they could do ALL aspects of repair, including Diagnostics and CIP!
