Not simply has BMW electrical architecture changed throughout the last decade, but so gets the equipment to service them. The gear has changed, the interfaces have changed and also the complexity of setup and use.
Early tools
In the 1990’s, the Group Tester One (GT1) was introduced. There are a number of versions, like DIS Plus (stationary setup), nevertheless the GT1 is regarded as the common and is also what’s going to be referenced here. The GT1 is often a portable device which contained a rechargeable battery. It possesses 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 could Diagnose the issue, lookup the way to switch the component then carry out the needed initializations for the new part. Two interfaces were utilised: EDIC (yellow interface) and also the OPS (orange interface). Later versions with the OPS were called OPPS, because they carried additional diagnostics for the Byteflite system plus they were also yellow, but much bigger compared to the EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are several “cloned” units around, adapted to function on the PC. Either genuine or cloned, the interfaces work the same and repair through an Ethernet port.
Later versions with the GT1 software removed CIP, and moved it to some separate computer (for storage), but nonetheless accessible through 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 each car (DIAGBUS and MOST bus simultaneously).
Third Generation equipment
Go forward about 2008 in the event the Third Generation (3G) of equipment premiered: ISIS. The items in ISIS are very large, that server colocation are set up at the dealership. A web-based version can be acquired on the aftermarket for a small fee, called OSS. It is usually bmw ista tutorial. Together with the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS has a few parts, because it completely replaced GT1 & Progman. The principle part of ISIS that is used from 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 is available just about anyplace, including eBay for very cheap. BMW seen that the tool was easily cloned and sold worldwide. Many levels of security have already been place into the roll-out of ISIS to stop this, in resident servers and internet based versions. This makes it more difficult for non-dealer shops to function about the newer cars. One could feel that since the GT1 was discontinued last year, you could just keep using that for a lot of more years prior to the newer system became more available, however, BMW stayed a measure ahead! When a car is programmed using the new ISTA/P, it upgrades the software beyond the amount of what Program can recognize. That means, each car has been updated with ISTA/P, you’ll never use Progman about it again, rendering the “cloned” versions useless on that particular car. Also, whenever a new module is installed, the software that is certainly pre-installed on that module can be newer when compared with Program can recognize, which can stop the entire programming process, forcing the vehicle to get programmed by ISTA/P.
What exactly does this mean for the BMW owner? Due to the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops can also be sending the cars to dealerships as a result. However, don’t assume all aftermarket shops have fallen behind. There’s a small selection of of BMW specialty shops that stick to surface of manufacturer technology, to ensure no car is averted! While looking for a place to service your BMW, make sure they could do ALL aspects of repair, including Diagnostics and CIP!
