Not only has BMW electrical architecture changed over the past decade, but so has the equipment to service them. The apparatus has changed, the interfaces have changed along with the complexity of setup and make use of.
Early tools
Back in the 1990’s, the Group Tester One (GT1) was introduced. There was a number of versions, like DIS Plus (stationary setup), though the GT1 is the most common and is also what is going to be referenced here. The GT1 is a portable device which contained a chargeable battery. It has a touchscreen display for straightforward use. It contained software for Diagnosing plus 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 the same tool, you may Diagnose the problem, research how to switch the component and after that carry out the needed initializations for that new part. Two interfaces were utilised: EDIC (yellow interface) along with the OPS (orange interface). Later versions in the OPS were called OPPS, given that they carried additional diagnostics for that Byteflite system and they also were also yellow, but larger as opposed to EDIC. Authentic GT1s take presctiption the portable touchscreen unit. There are numerous “cloned” units available, adapted to function over a PC. Either genuine or cloned, the interfaces work precisely the same and fasten through an Ethernet port.
Later versions in 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 the CIP functions and added extra features like multiple car programming and dual channel programming for every car (DIAGBUS and many bus simultaneously).
Third Generation equipment
Go forward about 2008 once the Third Generation (3G) of kit was released: ISIS. The valuables in ISIS are so large, that web site hosting are installed in the dealership. An online version is accessible towards the aftermarket for a small charge, called OSS. It could be bmw acceleration video. With all the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS is made up of few parts, as it completely replaced GT1 & Progman. The main portion of ISIS that is utilized within the shop is named “ISTA”, which can be further broken down into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s are available almost anyplace, including eBay for very cheap. BMW seen that the tool was easily cloned and sold worldwide. Many numbers of security have been placed into the growth of ISIS in order to avoid this, in resident servers and internet based versions. This will make it much harder for non-dealer shops to function on the newer cars. You are likely to think that because the GT1 was discontinued last year, you may just keep using that for several more years before newer system became more available, however, BMW stayed a pace ahead! Whenever a car is programmed with all the new ISTA/P, it upgrades the software program at night degree of what Program can recognize. That means, each car has been updated with ISTA/P, you can NEVER use Progman about it again, rendering the “cloned” versions useless with that particular car. Also, every time a new module is installed, the software program which is pre-installed with that module can also be newer compared to what Program can recognize, which may steer clear of the entire programming process, forcing the automobile to become programmed by ISTA/P.
Precisely what does this mean for that BMW owner? Due to the newer systems, many BMW owners can no longer repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships as a result. However, not all aftermarket shops have fallen behind. There’s a small number of of BMW specialty shops that stay with the surface of manufacturer technology, so that no car is beaten down! While looking for a location to service your BMW, make sure they can do ALL aspects of repair, including Diagnostics and CIP!
