Not simply has BMW electrical architecture changed over the last decade, but so gets the equipment to service them. The gear changed, the interfaces have changed along with the complexity of setup and make use of.
Early tools
Back in the 1990’s, the gang Tester One (GT1) was introduced. There were a number of versions, like DIS Plus (stationary setup), even so the GT1 is easily the most common and is what is going to be referenced here. The GT1 is really a portable device which contained a rechargeable battery. It has a touchscreen display for simple use. It contained software for Diagnosing and in addition 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 the same tool, you may Diagnose the issue, search for how to replace the component and then perform needed initializations for your new part. Two interfaces were utilized: EDIC (yellow interface) as well as the OPS (orange interface). Later versions with the OPS were called OPPS, since they carried additional diagnostics for your Byteflite system and they were also yellow, but much bigger compared to EDIC. Authentic GT1s are on the portable touchscreen unit. There are several “cloned” units available, adapted to work over a PC. Either genuine or cloned, the interfaces work the same and repair with an Ethernet port.
Later versions with the GT1 software removed CIP, and moved it to some separate computer (for storage), however accessible from 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 and every car (DIAGBUS and many bus simultaneously).
Third Generation equipment
Skip forward to around 2008 once the Third Generation (3G) of equipment premiered: ISIS. The valuables in ISIS are really large, that server colocation are installed with the dealership. An online version can be acquired for the aftermarket for a fee, called OSS. It can be bmw videos. With all the introduction of ISIS comes a 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 a part of ISIS that is used in the shop is termed “ISTA”, that may be further separated 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 very cheap. BMW realized that the tool was easily cloned and sold worldwide. Many numbers of security have been put into the growth of ISIS to stop this, both in resident servers and internet based versions. This will make it more difficult for non-dealer shops to work around the newer cars. You are likely to believe considering that the GT1 was discontinued during 2009, you may just keep using for a lot of more years until the newer system became more available, however, BMW stayed a stride ahead! When a car is programmed using the new ISTA/P, it upgrades the program at night a higher level what Program can recognize. This means, when a car has become updated with ISTA/P, you’ll never use Progman on it again, rendering the “cloned” versions useless on that particular car. Also, whenever a new module is installed, the program that is certainly pre-installed on that module is additionally newer than Program can recognize, which could stop the entire programming process, forcing the automobile to be programmed by ISTA/P.
So what does this mean for your BMW owner? As a result of the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops can also be sending the cars to dealerships because of this. However, don’t assume all aftermarket shops have fallen behind. There’s a limited number of BMW specialty shops that stay on the surface of manufacturer technology, to ensure no car is beaten down! When searching for a location to service your BMW, make certain they could do ALL aspects of repair, including Diagnostics and CIP!
