Not simply has BMW electrical architecture changed during the last decade, but so contains the equipment to service them. The gear has changed, the interfaces have changed as well as the complexity of setup and use.
Early tools
Back in the 1990’s, the audience Tester One (GT1) was introduced. There have been several versions, like DIS Plus (stationary setup), nevertheless the GT1 is regarded as the common and it is after that be referenced here. The GT1 is a portable device which contained a rechargeable battery. It features a touchscreen display screen for straightforward 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 might Diagnose the situation, look up how you can replace the component after which do the needed initializations for that new part. Two interfaces were used: EDIC (yellow interface) and the OPS (orange interface). Later versions of the OPS were called OPPS, because they carried additional diagnostics for that Byteflite system and so they were also yellow, but much wider as opposed to EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are numerous “cloned” units out there, adapted to be effective with a PC. Either genuine or cloned, the interfaces work precisely the same and fasten by using an Ethernet port.
Later versions of the GT1 software removed CIP, and moved it with a separate computer (for storage), but nevertheless accessible from the GT1. This new software was called Progman (short for Program Manager). This new software contained each of the CIP functions and added new features like multiple car programming and dual channel programming for every car (DIAGBUS and MOST bus simultaneously).
Third Generation equipment
Go forward about 2008 when the Third Generation (3G) of apparatus premiered: ISIS. The valuables in ISIS are really large, that dedicated servers are set up on the dealership. A web based version can be obtained to the aftermarket for a fee, called OSS. It may be bmw ilevel. With the introduction of ISIS comes a new interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS is made up of few parts, because it completely replaced GT1 & Progman. The key portion of ISIS utilized in the shop is known as “ISTA”, which can be 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 really cheap. BMW realized that the tool was easily cloned and sold worldwide. Many numbers of security have been put into the development of ISIS in order to avoid this, both in resident servers an internet-based versions. It is then harder for non-dealer shops to be effective about the newer cars. You are likely to feel that since GT1 was discontinued in 2009, you might just keep using that for a lot of more years before newer system became more available, however, BMW stayed one step ahead! Whenever a car is programmed with all the new ISTA/P, it upgrades the software past the level of what Program can recognize. Meaning, when a car has been updated with ISTA/P, you cant ever use Progman about it again, rendering the “cloned” versions useless with that particular car. Also, when a new module is installed, the software which is pre-installed with that module is additionally newer when compared with Program can recognize, which could steer clear of the entire programming process, forcing the vehicle to be programmed by ISTA/P.
So what does this mean for that BMW owner? On account of the newer systems, many BMW owners still can’t repair the cars themselves. Many aftermarket shops may also be sending the cars to dealerships therefore. However, not all aftermarket shops have fallen behind. There’s a limited number of BMW specialty shops that stay on top of manufacturer technology, in order that no car is rejected! While looking for a place to service your BMW, make certain they could do Every aspect of repair, including Diagnostics and CIP!
