Not merely has BMW electrical architecture changed throughout the last decade, but so has got the equipment to service them. The apparatus is different, the interfaces have changed as well as the complexity of setup and employ.
Early tools
In the 1990’s, the gang Tester One (GT1) was introduced. There was several versions, like DIS Plus (stationary setup), though the GT1 is regarded as the common and is what will be referenced here. The GT1 is a portable device which contained a rechargeable battery. It has a touchscreen technology for straightforward 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 could Diagnose the challenge, lookup how you can replace the component and then carry out the needed initializations for your new part. Two interfaces were chosen: EDIC (yellow interface) and also the OPS (orange interface). Later versions in the OPS were called OPPS, given that they carried additional diagnostics for your Byteflite system plus they were also yellow, but larger than the EDIC. Authentic GT1s take presctiption the portable touchscreen unit. There are lots of “cloned” units out there, adapted to function with a PC. Either genuine or cloned, the interfaces work precisely the same and correct with an Ethernet port.
Later versions in the GT1 software removed CIP, and moved it with a separate computer (for storage), but still 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 latest features like multiple car programming and dual channel programming for every car (DIAGBUS and MOST bus simultaneously).
Third Generation equipment
Skip ahead about 2008 in the event the Third Generation (3G) of equipment was launched: ISIS. The items in ISIS are really large, that dedicated servers are set up on the dealership. A web based version is available on the aftermarket for a small fee, called OSS. It may be bmw ista tutorial. Together with the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS has a few parts, since it completely replaced GT1 & Progman. The key portion of ISIS that is utilized in the shop is known as “ISTA”, which may be further categorised into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s is found just about anywhere, including eBay for cheap. BMW pointed out that the tool was easily cloned and sold worldwide. Many numbers of security have already been place into the development of ISIS in order to avoid this, in resident servers and internet based versions. This will make it more difficult for non-dealer shops to function around the newer cars. You are likely to feel that since GT1 was discontinued in 2009, you could just keep using for many more years prior to the newer system became more available, however, BMW stayed one step ahead! Whenever a car is programmed with the new ISTA/P, it upgrades the application beyond the a higher level what Program can recognize. Which means, once a car has been updated with ISTA/P, you cant ever use Progman onto it again, rendering the “cloned” versions useless with that particular car. Also, when a new module is installed, the application which is pre-installed with that module is also newer than Program can recognize, which may stay away from the entire programming process, forcing the auto to be programmed by ISTA/P.
Precisely what does this mean for your BMW owner? On account of the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops can also be sending the cars to dealerships as a result. However, its not all aftermarket shops have fallen behind. You can find a limited number of BMW specialty shops that stay on surface of manufacturer technology, to ensure no car is rejected! While searching for an area to service your BMW, be sure they are able to do ALL aspects of repair, including Diagnostics and CIP!
