Not just has BMW electrical architecture changed during the last decade, but so contains the equipment to service them. The equipment has changed, the interfaces have changed and also the complexity of setup and employ.
Early tools
In the 1990’s, the viewers Tester One (GT1) was introduced. There were a few versions, like DIS Plus (stationary setup), though the GT1 is easily the most common and is what is going to be referenced here. The GT1 is a portable device which contained a rechargeable battery. It features a touchscreen technology for straightforward use. It contained software for Diagnosing plus 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 in the same tool, you can Diagnose the situation, research how you can switch the component and after that do 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, because they carried additional diagnostics for your Byteflite system plus they were also yellow, but larger as opposed to EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are lots of “cloned” units available, adapted to function with a PC. Either genuine or cloned, the interfaces work exactly the same and connect through an Ethernet port.
Later versions in the GT1 software removed CIP, and moved it to some separate computer (for storage), but nevertheless accessible in the GT1. This new software was called Progman (short for Program Manager). This new software contained each of the CIP functions and added extra features like multiple car programming and dual channel programming for every car (DIAGBUS and quite a few bus simultaneously).
Third Generation equipment
Skip ahead about 2008 if the Third Generation (3G) of it technology was launched: ISIS. The valuables in ISIS are extremely large, that server colocation are installed on the dealership. A web based version can be acquired towards the aftermarket for a fee, called OSS. It can be bmw acceleration video. With the introduction of ISIS comes a whole new interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS includes a few parts, since it completely replaced GT1 & Progman. The primary part of ISIS that is utilized in the shop is known as “ISTA”, that may be further broken down into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s is found almost anyplace, including eBay for really cheap. BMW seen that the tool was easily cloned and sold worldwide. Many levels of security have already been put in the creation of ISIS in order to avoid this, in the resident servers an internet-based versions. This will make it much harder for non-dealer shops to function for the newer cars. You are likely to believe since GT1 was discontinued in 2009, you can keep using for a number of more years before newer system became more available, however, BMW stayed a stride ahead! When a car is programmed using the new ISTA/P, it upgrades the software program past the degree of what Program can recognize. That means, when a car continues to be updated with ISTA/P, you cant ever use Progman onto it again, rendering the “cloned” versions useless with that particular car. Also, every time a new module is installed, the software program which is pre-installed with that module can also be newer compared to what Program can recognize, that may stay away from the entire programming process, forcing the car to be programmed by ISTA/P.
So what does that mean for your BMW owner? As a result of the newer systems, many BMW owners can no longer repair the cars themselves. Many aftermarket shops can also be sending the cars to dealerships consequently. However, not every aftermarket shops have fallen behind. There is a select few of BMW specialty shops that remain on surface of manufacturer technology, to ensure that no car is turned away! When looking for a spot to service your BMW, ensure they could do ALL aspects of repair, including Diagnostics and CIP!
