Not only has BMW electrical architecture changed over the last decade, but so has got the equipment to service them. The apparatus has changed, the interfaces have changed as well as the complexity of setup and rehearse.
Early tools
During the 1990’s, the gang Tester One (GT1) was introduced. There are a couple of versions, like DIS Plus (stationary setup), though the GT1 is the most common which is after that be referenced here. The GT1 is really a portable device which contained a chargeable battery. It features 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 could Diagnose the challenge, look up the best way to switch the component and after that perform the needed initializations for that new part. Two interfaces were utilised: EDIC (yellow interface) and the OPS (orange interface). Later versions with the OPS were called OPPS, because they carried additional diagnostics for that Byteflite system and they were also yellow, but much larger than the EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are lots of “cloned” units available, adapted to operate on a PC. Either genuine or cloned, the interfaces work precisely the same and fasten via an Ethernet port.
Later versions with the GT1 software removed CIP, and moved it with 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 all the CIP functions and added extra features like multiple car programming and dual channel programming for each and every car (DIAGBUS and MOST bus simultaneously).
Third Generation equipment
Skip ahead to about 2008 in the event the Third Generation (3G) of apparatus premiered: ISIS. The items in ISIS are so large, that dedicated servers are set up with the dealership. A web-based version is accessible for the aftermarket for a small fee, called OSS. It could be bmw diagnostic software. Together 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, since it completely replaced GT1 & Progman. The principle portion of ISIS utilized from the shop is named “ISTA”, which is often further separated into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s are available just about anywhere, including eBay for inexpensive. BMW realized that the tool was easily cloned and sold worldwide. Many amounts of security are already place into the development of ISIS to avoid this, in both resident servers and internet-based versions. It is then more difficult for non-dealer shops to operate around the newer cars. You are likely to believe that because the GT1 was discontinued during 2009, you could keep using that for several more years before newer system became more available, however, BMW stayed a pace ahead! When a car is programmed with all the new ISTA/P, it upgrades the software program past the a higher level what Program can recognize. Meaning, each car has become updated with ISTA/P, you’ll never use Progman onto it again, rendering the “cloned” versions useless on that particular car. Also, each time a new module is installed, the software program that’s pre-installed on that module is also newer than Program can recognize, which can stay away from the entire programming process, forcing the auto being programmed by ISTA/P.
What exactly does which means that for that BMW owner? On account of the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops may also be sending the cars to dealerships consequently. However, its not all aftermarket shops have fallen behind. There’s a limited number of BMW specialty shops that stay with top of manufacturer technology, in order that no car is rejected! While looking for a place to service your BMW, make certain they are able to do ALL aspects of repair, including Diagnostics and CIP!
