BMW Services Technological innovation - The Evolution of Diagnostic Gear

Not only has BMW electrical architecture transformed in excess of the final decade, but so has the tools to service them. The gear has changed, the interfaces have altered and also inpa of set up and use.

Early tools

Again in the 1990's, the Group Tester A single (GT1) was introduced. There have been a few versions, like DIS Plus (stationary set up), even so the GT1 is the most frequent and is what will be referenced below. The GT1 is a transportable system which contained a rechargeable battery. It has a touchscreen show for straightforward use. It contained software program for Diagnosing and also experienced application known as TIS (Complex Details Show) which is the Support & Restore Data. Early versions of Diagnostics also contained software program called Coding, Programming & Individualization (CIP). So from the identical tool, you could Diagnose the issue, seem up how to exchange the element and then execute the essential initializations for the new component. Two interfaces ended up used: EDIC (yellow interface) and the OPS (orange interface). Later versions of the OPS have been referred to as OPPS, considering that they carried added diagnostics for the Byteflite method and they were also yellow, but much greater than the EDIC. Genuine GT1s are on the transportable touchscreen device. There are numerous "cloned" units out there, tailored to function on a Computer. Possibly real or cloned, the interfaces work the very same and link through an Ethernet port.

Later on versions of the GT1 software removed CIP, and moved it to a individual computer (for storage), but even now accessible from the GT1. This new computer software was known as Progman (quick for Software Supervisor). This new software contained all of the CIP features and extra new features like several vehicle programming and dual channel programming for each vehicle (DIAGBUS and MOST bus concurrently).

Third Era products

Quick ahead to about 2008 when the 3rd Generation (3G) of products was introduced: ISIS. The contents of ISIS are so massive, that focused servers are installed at the dealership. An online version is accessible to the aftermarket for a price, named OSS. It can be located at BMW's tech internet site. With the introduction of ISIS comes a new interface, named ICOM. Previous interfaces (EDIC & OPS) will not likely function with ISIS. ISIS consists of a few parts, considering that it entirely replaced GT1 & Progman. The major element of ISIS that is employed in the shop is referred to as "ISTA", which can be even more damaged down into two areas: ISTA/D for Diagnosing autos and ISTA/P for Coding, Programming & Individualization.


GT1s can be identified just about wherever, including eBay for very low cost. BMW understood that the instrument was very easily cloned and sold around the world. Several ranges of security have been set into the creation of ISIS to avert this, in the two resident servers and on the internet variations. This makes it significantly tougher for non-supplier retailers to perform on the more recent automobiles. A single would feel that given that the GT1 was discontinued in 2009, you could just keep utilizing that for a number of much more a long time until the more recent program became more accessible, nevertheless, BMW stayed a single action forward! Whenever a automobile is programmed with the new ISTA/P, it upgrades the software program outside of the stage of what Software can understand. That means, when a automobile has been up to date with ISTA/P, you can By no means use Progman on it again, rendering the "cloned" variations useless on that particular auto. Also, when a new module is set up, the software program that is pre-set up on that module is also more recent than what System can understand, which can stop the entire programming approach, forcing the car to be programmed by ISTA/P.

So what does that suggest for the BMW operator? As a result of the more recent programs, several BMW proprietors can no more time restore the vehicles them selves. Numerous aftermarket outlets are also sending the automobiles to dealerships as a consequence. Nevertheless, not all aftermarket retailers have fallen guiding. There are a pick handful of of BMW specialty shops that remain on leading of producer engineering, so that no vehicle is turned away! When seeking for a place to services your BMW, make sure they can do ALL elements of restore, such as Diagnostics and CIP!
