Not simply has BMW electrical architecture changed during the last decade, but so contains the equipment to service them. The device is different, 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 was a number of versions, like DIS Plus (stationary setup), however the GT1 is the most common which is what’s going to be referenced here. The GT1 is really a portable device which contained a chargeable battery. It provides a touchscreen display screen for easy use. It contained software for Diagnosing and also had software called TIS (Technical Information Display) which is the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So from your same tool, you might Diagnose the challenge, lookup how to switch the component then perform the needed initializations for your new part. Two interfaces were utilized: EDIC (yellow interface) along with the OPS (orange interface). Later versions in the OPS were called OPPS, simply because they carried additional diagnostics for your Byteflite system plus they were also yellow, but much bigger as opposed to EDIC. Authentic GT1s take presctiption the portable touchscreen unit. There are several “cloned” units out there, adapted to be effective with a PC. Either genuine or cloned, the interfaces work precisely the same and correct by using an Ethernet port.
Later versions in the GT1 software removed CIP, and moved it with a separate computer (for storage), but nevertheless accessible from your GT1. This new software was called Progman (short for Program Manager). This new software contained all the CIP functions and added additional features like multiple car programming and dual channel programming for each car (DIAGBUS and quite a few bus simultaneously).
Third Generation equipment
Go forward to about 2008 in the event the Third Generation (3G) of equipment was launched: ISIS. The items in ISIS are extremely large, that web site hosting are set up on the dealership. A web-based version is available on the aftermarket for a small fee, called OSS. It may be bmw acceleration video. With the introduction of ISIS comes a brand new interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS consists of a few parts, since it completely replaced GT1 & Progman. The main a part of ISIS which is used from the shop is called “ISTA”, which may be further separated into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s are available just about anywhere, including eBay for cheap. BMW pointed out that the tool was easily cloned and sold worldwide. Many levels of security have already been put into the roll-out of ISIS in order to avoid this, in resident servers an internet-based versions. It is then much harder for non-dealer shops to be effective around the newer cars. You might believe since GT1 was discontinued in ’09, you might just keep by using their for many more years until the newer system became more available, however, BMW stayed one step ahead! Whenever a car is programmed together with the new ISTA/P, it upgrades the program after dark degree of what Program can recognize. This means, after a car has been updated with ISTA/P, you can NEVER use Progman onto it again, rendering the “cloned” versions useless on that particular car. Also, whenever a new module is installed, the program that is pre-installed on that module is also newer than Program can recognize, which can stay away from the entire programming process, forcing the car being programmed by ISTA/P.
So what does which means that for your BMW owner? Due to the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops are also sending the cars to dealerships therefore. However, not all aftermarket shops have fallen behind. There’s a small number of of BMW specialty shops that stick to the top of manufacturer technology, so that no car is averted! When looking for a place to service your BMW, be sure they’re able to do Every aspect of repair, including Diagnostics and CIP!
