Not simply has BMW electrical architecture changed throughout the last decade, but so has got the equipment to service them. The apparatus is different, the interfaces have changed along with the complexity of setup and use.
Early tools
Back in the 1990’s, the Group Tester One (GT1) was introduced. There are a few versions, like DIS Plus (stationary setup), though 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 plus 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 in the same tool, you might Diagnose the challenge, look up how you can switch the component and after that do the needed initializations for your new part. Two interfaces were utilised: 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 so they were also yellow, but much larger compared to the EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are many “cloned” units on the market, adapted to be effective with a PC. Either genuine or cloned, the interfaces work exactly the same and repair through an Ethernet port.
Later versions with the GT1 software removed CIP, and moved it with a separate computer (for storage), but still 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 forward to about 2008 in the event the Third Generation (3G) of kit was published: ISIS. The contents of ISIS are extremely large, that hosting are set up with the dealership. An online version can be obtained to the aftermarket for their fee, called OSS. It is usually bmw kombi coding. With all the introduction of ISIS comes a whole new interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS has a few parts, as it completely replaced GT1 & Progman. The principle part of ISIS that is used in the shop is termed “ISTA”, which can be further separated into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s can be found almost anyplace, including eBay for inexpensive. BMW seen that the tool was easily cloned and sold worldwide. Many degrees of security happen to be place into the development of ISIS to stop this, in the resident servers and online versions. It is then much harder for non-dealer shops to be effective about the newer cars. One could believe that since the GT1 was discontinued in 2009, you might keep using that for several more years until the newer system became more available, however, BMW stayed a stride ahead! When a car is programmed together with the new ISTA/P, it upgrades the software beyond the amount of what Program can recognize. Meaning, each car has been updated with ISTA/P, you can NEVER use Progman into it again, rendering the “cloned” versions useless with that particular car. Also, each time a new module is installed, the software that is certainly pre-installed with that module is also newer than Program can recognize, which can steer clear of the entire programming process, forcing the vehicle being programmed by ISTA/P.
So what does that mean for your BMW owner? As a result of the newer systems, many BMW owners can’t repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships consequently. However, don’t assume all aftermarket shops have fallen behind. You can find a small number of of BMW specialty shops that stay with surface of manufacturer technology, to ensure that no car is rejected! When looking for an area to service your BMW, make certain they can do Every aspect of repair, including Diagnostics and CIP!
