BMW Service Technologies - The Evolution of Diagnostic Tools

Not only has BMW electrical architecture altered above inpa , but so has the tools to service them. The products has altered, the interfaces have transformed and also the complexity of setup and use.

Early equipment

Back again in the 1990's, the Group Tester A single (GT1) was introduced. There were a number of variations, like DIS Additionally (stationary set up), even so the GT1 is the most frequent and is what will be referenced below. The GT1 is a portable unit which contained a rechargeable battery. It has a touchscreen show for effortless use. It contained application for Diagnosing and also had software program referred to as TIS (Specialized Information Screen) which is the Support & Mend Information. Early variations of Diagnostics also contained software known as Coding, Programming & Individualization (CIP). So from the exact same resource, you could Diagnose the dilemma, look up how to change the ingredient and then execute the essential initializations for the new portion. Two interfaces ended up utilised: EDIC (yellow interface) and the OPS (orange interface). Later on variations of the OPS were named OPPS, since they carried further diagnostics for the Byteflite technique and they ended up also yellow, but a lot bigger than the EDIC. Reliable GT1s are on the portable touchscreen unit. There are numerous "cloned" units out there, adapted to perform on a Pc. Either genuine or cloned, the interfaces operate the very same and hook up by way of an Ethernet port.

Later on variations of the GT1 application taken out CIP, and moved it to a independent laptop (for storage), but nevertheless available from the GT1. This new software was called Progman (limited for Plan Manager). This new application contained all of the CIP features and added new functions like multiple car programming and twin channel programming for every single vehicle (DIAGBUS and MOST bus concurrently).

Third Generation products

Fast forward to about 2008 when the 3rd Generation (3G) of products was released: ISIS. The contents of ISIS are so massive, that committed servers are put in at the dealership. An online version is accessible to the aftermarket for a payment, called OSS. It can be discovered at BMW's tech internet site. With the introduction of ISIS comes a new interface, referred to as ICOM. Previous interfaces (EDIC & OPS) is not going to work with ISIS. ISIS is composed of a handful of elements, given that it completely replaced GT1 & Progman. The main portion of ISIS that is used in the store is named "ISTA", which can be additional broken down into two elements: ISTA/D for Diagnosing cars and ISTA/P for Coding, Programming & Individualization.


GT1s can be located just about anyplace, which includes eBay for really low cost. BMW understood that the resource was effortlessly cloned and offered worldwide. Several levels of protection have been place into the generation of ISIS to avoid this, in each resident servers and on-line versions. This tends to make it considerably more difficult for non-supplier outlets to work on the newer cars. A single would feel that considering that the GT1 was discontinued in 2009, you could just maintain utilizing that for several far more many years right up until the more recent method became more accessible, even so, BMW stayed a single action forward! Each time a auto is programmed with the new ISTA/P, it updates the application over and above the stage of what Plan can acknowledge. That signifies, when a automobile has been current with ISTA/P, you can By no means use Progman on it once more, rendering the "cloned" versions useless on that certain automobile. Also, when a new module is installed, the software that is pre-mounted on that module is also newer than what Program can recognize, which can end the whole programming approach, forcing the car to be programmed by ISTA/P.

So what does that indicate for the BMW proprietor? As a result of the more recent programs, numerous BMW house owners can no longer repair the autos by themselves. Several aftermarket retailers are also sending the autos to dealerships as a consequence. Even so, not all aftermarket stores have fallen driving. There are a decide on handful of of BMW specialty retailers that continue to be on leading of company engineering, so that no auto is turned absent! When searching for a place to support your BMW, make certain they can do ALL facets of fix, like Diagnostics and CIP!
