Not merely has BMW electrical architecture changed during the last decade, but so gets the equipment to service them. The device has changed, the interfaces have changed along with the complexity of setup and employ.
Early tools
Within the 1990’s, the viewers Tester One (GT1) was introduced. There was several versions, like DIS Plus (stationary setup), though the GT1 is easily the most common which is what is going to be referenced here. The GT1 is really a portable device which contained a chargeable battery. It has a touchscreen display for straightforward use. It contained software for Diagnosing and also 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 could Diagnose the situation, lookup the best way to replace the component and then carry out the needed initializations to the new part. Two interfaces were utilized: EDIC (yellow interface) and the OPS (orange interface). Later versions of the OPS were called OPPS, because they carried additional diagnostics to the Byteflite system and they were also yellow, but much larger compared to the EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are numerous “cloned” units available, adapted to be effective with a PC. Either genuine or cloned, the interfaces work the identical and connect with an Ethernet port.
Later versions of the GT1 software removed CIP, and moved it to some separate computer (for storage), but nonetheless accessible from the GT1. This new software was called Progman (short for Program Manager). This new software contained all of the CIP functions and added extra features like multiple car programming and dual channel programming for every car (DIAGBUS and MOST bus simultaneously).
Third Generation equipment
Fast forward to around 2008 once the Third Generation (3G) of kit was launched: ISIS. The valuables in ISIS are extremely large, that hosting are set up at the dealership. An internet version can be obtained for the aftermarket for their fee, called OSS. It may be bmw diagnostic software. With all the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS includes a few parts, as it completely replaced GT1 & Progman. The primary section of ISIS utilized within the shop is called “ISTA”, which may be further broken down 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 very cheap. BMW pointed out that the tool was easily cloned and sold worldwide. Many amounts of security are already placed into the development of ISIS to stop this, in both resident servers and online versions. This will make it much harder for non-dealer shops to be effective on the newer cars. You are likely to feel that since GT1 was discontinued in ’09, you could keep using for many 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 program after dark amount of what Program can recognize. Meaning, once a car may be updated with ISTA/P, you can NEVER use Progman on it again, rendering the “cloned” versions useless on that particular car. Also, when a new module is installed, the program that’s pre-installed on that module can also be newer than what Program can recognize, which could stay away from the entire programming process, forcing the automobile being programmed by ISTA/P.
Precisely what does which means that to the 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 consequently. However, don’t assume all aftermarket shops have fallen behind. There’s a limited number of BMW specialty shops that stick to surface of manufacturer technology, so that no car is turned away! While searching for a location to service your BMW, be sure they can do Every aspect of repair, including Diagnostics and CIP!
