Not simply has BMW electrical architecture changed throughout the last decade, but so contains the equipment to service them. The equipment is different, the interfaces have changed and also the complexity of setup and make use of.
Early tools
Back in the 1990’s, the viewers Tester One (GT1) was introduced. There are a number of versions, like DIS Plus (stationary setup), though the GT1 is among the most common and it is after that be referenced here. The GT1 is often a portable device which contained a rechargeable battery. It provides a touchscreen technology for straightforward use. It contained software for Diagnosing and also had software called TIS (Technical Information Display) the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So through the same tool, you might Diagnose the situation, search for the way to replace the component and then perform the needed initializations for the new part. Two interfaces were used: EDIC (yellow interface) and also the OPS (orange interface). Later versions of the OPS were called OPPS, since they carried additional diagnostics for the Byteflite system and so they were also yellow, but much larger compared to the EDIC. Authentic GT1s take presctiption the portable touchscreen unit. There are many “cloned” units on the market, adapted to be effective on a PC. Either genuine or cloned, the interfaces work precisely the same and correct through an Ethernet port.
Later versions of the GT1 software removed CIP, and moved it to a separate computer (for storage), but nevertheless 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 new features like multiple car programming and dual channel programming for every car (DIAGBUS and quite a few bus simultaneously).
Third Generation equipment
Skip forward about 2008 if the Third Generation (3G) of equipment was published: ISIS. The items in ISIS are very large, that dedicated servers are installed in the dealership. An online version can be acquired on the aftermarket for a small charge, called OSS. It can be bmw ista. Using the introduction of ISIS comes a new interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS includes a few parts, because it completely replaced GT1 & Progman. The main section of ISIS which is used in the shop is termed “ISTA”, which is often further categorised into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s is available anywhere you want to, including eBay for really cheap. BMW realized that the tool was easily cloned and sold worldwide. Many amounts of security have already been put in the growth of ISIS to stop this, both in resident servers and internet based versions. This makes it much harder for non-dealer shops to be effective on the newer cars. You might believe that since GT1 was discontinued during 2009, you might keep using that for many more years prior to the newer system became more available, however, BMW stayed a pace ahead! When a car is programmed with all the new ISTA/P, it upgrades the software at night a higher level what Program can recognize. This means, each 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 software that’s pre-installed on that module is also newer when compared with Program can recognize, which could steer clear of the entire programming process, forcing the vehicle to become programmed by ISTA/P.
Just what exactly does this mean for the BMW owner? On account of the newer systems, many BMW owners can’t repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships as a result. However, not every aftermarket shops have fallen behind. There are a select few of BMW specialty shops that stay with the top of manufacturer technology, to ensure that no car is beaten down! When looking for a place to service your BMW, be sure they could do ALL aspects of repair, including Diagnostics and CIP!
