Not just has BMW electrical architecture changed during the last decade, but so has got the equipment to service them. The gear has evolved, the interfaces have changed and also the complexity of setup and employ.
Early tools
During the 1990’s, the gang Tester One (GT1) was introduced. There have been a couple of versions, like DIS Plus (stationary setup), nevertheless the GT1 is the most common and is what’s going to be referenced here. The GT1 can be a portable device which contained a chargeable battery. It possesses a touchscreen technology for simple use. It contained software for Diagnosing and also 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 could Diagnose the problem, search for how to switch the component and then carry out the needed initializations to the new part. Two interfaces were used: EDIC (yellow interface) as well as the OPS (orange interface). Later versions from 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 EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are several “cloned” units available, adapted to work with a PC. Either genuine or cloned, the interfaces work the same and fasten through an Ethernet port.
Later versions from the GT1 software removed CIP, and moved it into a separate computer (for storage), however accessible through the GT1. This new software was called Progman (short for Program Manager). This new software contained all of the CIP functions and added additional features like multiple car programming and dual channel programming per car (DIAGBUS and MOST bus simultaneously).
Third Generation equipment
Fast forward to around 2008 when the Third Generation (3G) of it technology premiered: ISIS. The contents of ISIS are really large, that hosting are installed with the dealership. An online version is available for the aftermarket for a small charge, called OSS. It could be bmw idrive coding. With the introduction of ISIS comes a whole new interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS consists of a few parts, as it completely replaced GT1 & Progman. The principle part of ISIS that is utilized from the shop is termed “ISTA”, which can be further categorised into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s are available just about anyplace, including eBay for really cheap. BMW pointed out that the tool was easily cloned and sold worldwide. Many numbers of security have been put into the roll-out of ISIS in order to avoid this, in the resident servers and internet-based versions. This will make it more difficult for non-dealer shops to work about the newer cars. You are likely to believe because the GT1 was discontinued during 2009, you could just keep using that for a lot of more years until the newer system became more available, however, BMW stayed a stride ahead! Every time a car is programmed together with the new ISTA/P, it upgrades the program past the level of what Program can recognize. That means, after a car continues to be updated with ISTA/P, you cant ever use Progman about it again, rendering the “cloned” versions useless on that particular car. Also, each time a new module is installed, the program which 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 automobile to become programmed by ISTA/P.
What exactly does that mean to the BMW owner? Because of the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops are also sending the cars to dealerships consequently. However, not all aftermarket shops have fallen behind. There is a limited number of BMW specialty shops that stay with the top of manufacturer technology, in order that no car is turned away! When looking for an area to service your BMW, be sure they’re able to do ALL aspects of repair, including Diagnostics and CIP!
