Not only has BMW electrical architecture changed over the last decade, but so gets the equipment to service them. The equipment is different, the interfaces have changed plus the complexity of setup and rehearse.
Early tools
During the 1990’s, the audience Tester One (GT1) was introduced. There have been a couple of versions, like DIS Plus (stationary setup), however the GT1 is regarded as the common and it is after that be referenced here. The GT1 is often a portable device which contained a rechargeable battery. It features a touchscreen display screen for simple use. It contained software for Diagnosing as well as had software called TIS (Technical Information Display) which is the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So through the same tool, you could Diagnose the challenge, search for how you can switch the component and after that perform the needed initializations for your new part. Two interfaces were chosen: EDIC (yellow interface) as well as the OPS (orange interface). Later versions with the OPS were called OPPS, given that they carried additional diagnostics for your Byteflite system and they were also yellow, but larger than the EDIC. Authentic GT1s are on the portable touchscreen unit. There are lots of “cloned” units available, adapted to operate on the PC. Either genuine or cloned, the interfaces work exactly the same and repair by using an Ethernet port.
Later versions with 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 all the CIP functions and added latest features like multiple car programming and dual channel programming for every car (DIAGBUS and quite a few bus simultaneously).
Third Generation equipment
Fast forward about 2008 in the event the Third Generation (3G) of it technology premiered: ISIS. The contents of ISIS are extremely large, that web site hosting are installed at the dealership. A web-based version is available for the aftermarket for their fee, called OSS. It may be bmw fsc code. With all the introduction of ISIS comes a brand new interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS consists of a few parts, because it completely replaced GT1 & Progman. The principle portion of ISIS utilized inside the shop is called “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 is found just about anywhere, including eBay for really cheap. BMW seen that the tool was easily cloned and sold worldwide. Many numbers of security have already been place into the development of ISIS to stop this, both in resident servers and internet based versions. This will make it harder for non-dealer shops to operate on the newer cars. One would think that considering that the GT1 was discontinued during 2009, you could just keep using that for many more years prior to the newer system became more available, however, BMW stayed a stride ahead! Every time a car is programmed with all the new ISTA/P, it upgrades the application after dark a higher level what Program can recognize. That means, once a car has become updated with ISTA/P, you can NEVER use Progman on it again, rendering the “cloned” versions useless on that particular car. Also, each time a new module is installed, the application that’s pre-installed on that module can be newer when compared with Program can recognize, which can pun intended, the entire programming process, forcing the car being programmed by ISTA/P.
So what does that mean for your BMW owner? As a result of the newer systems, many BMW owners still can’t repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships because of this. However, its not all aftermarket shops have fallen behind. You can find a select few of BMW specialty shops that stay on top of manufacturer technology, to ensure no car is averted! While looking for a location to service your BMW, make sure they can do ALL aspects of repair, including Diagnostics and CIP!
