Not merely has BMW electrical architecture changed over the last decade, but so has got the equipment to service them. The device is different, the interfaces have changed plus the complexity of setup and employ.
Early tools
In the 1990’s, the viewers Tester One (GT1) was introduced. There were a couple of 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 a portable device which contained a rechargeable battery. It possesses a touchscreen display screen for simple use. It contained software for Diagnosing and in addition 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 through the same tool, you can Diagnose the problem, lookup how you can switch the component after which perform needed initializations to the new part. Two interfaces were used: EDIC (yellow interface) along with the OPS (orange interface). Later versions in the OPS were called OPPS, given that they carried additional diagnostics to the Byteflite system plus they were also yellow, but much wider compared to the EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are lots of “cloned” units on the market, adapted to function over a PC. Either genuine or cloned, the interfaces work precisely the same and fasten with an Ethernet port.
Later versions in the GT1 software removed CIP, and moved it to a separate computer (for storage), however 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 latest features like multiple car programming and dual channel programming for each car (DIAGBUS and a lot bus simultaneously).
Third Generation equipment
Fast forward to around 2008 in the event the Third Generation (3G) of kit was launched: ISIS. The items in ISIS are so large, that server colocation are set up at the dealership. An internet version can be obtained towards the aftermarket for a small charge, called OSS. It is usually itoolradar. Together with 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 key portion of ISIS utilized in the shop is called “ISTA”, that may be further broken down into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s is available almost anyplace, including eBay for really cheap. BMW realized that the tool was easily cloned and sold worldwide. Many numbers of security happen to be place into the growth of ISIS to prevent this, in the resident servers an internet-based versions. This makes it more difficult for non-dealer shops to function around the newer cars. You might believe that considering that the GT1 was discontinued during 2009, you can keep using that for a number of more years before 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 level of what Program can recognize. Meaning, when a car continues to be updated with ISTA/P, you cant ever use Progman onto it again, rendering the “cloned” versions useless on that particular car. Also, whenever a new module is installed, the application that is pre-installed on that module can be newer than what Program can recognize, which may steer clear of the entire programming process, forcing the auto being programmed by ISTA/P.
Precisely what does this mean to the BMW owner? As a result of the newer systems, many BMW owners still can’t repair the cars themselves. Many aftermarket shops are also sending the cars to dealerships as a result. However, don’t assume all aftermarket shops have fallen behind. There is a small selection of of BMW specialty shops that stay on top of manufacturer technology, to ensure no car is rejected! When looking for an area to service your BMW, make sure they could do ALL aspects of repair, including Diagnostics and CIP!
