Not just has BMW electrical architecture changed over the past decade, but so contains the equipment to service them. The gear has evolved, the interfaces have changed and also the complexity of setup and make use of.
Early tools
During the 1990’s, the Group Tester One (GT1) was introduced. There are a couple of versions, like DIS Plus (stationary setup), however the GT1 is regarded as the common which is after that be referenced here. The GT1 is a portable device which contained a chargeable battery. It has a touchscreen display screen 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 from the same tool, you can Diagnose the challenge, lookup how to replace the component and then perform needed initializations for the new part. Two interfaces were used: EDIC (yellow interface) and the OPS (orange interface). Later versions from the OPS were called OPPS, because they carried additional diagnostics for the Byteflite system and so they were also yellow, but larger than the EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are many “cloned” units on the market, adapted to work on a PC. Either genuine or cloned, the interfaces work exactly the same and connect with an Ethernet port.
Later versions from the GT1 software removed CIP, and moved it into a separate computer (for storage), but still accessible from the GT1. This new software was called Progman (short for Program Manager). This new software contained each of the CIP functions and added additional features like multiple car programming and dual channel programming for every car (DIAGBUS and many bus simultaneously).
Third Generation equipment
Skip ahead to around 2008 when the Third Generation (3G) of apparatus was published: ISIS. The contents of ISIS are very large, that web site hosting are set up with the dealership. An online version can be obtained for the aftermarket for a small fee, called OSS. It can be bmw kombi coding. Using the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS consists of a few parts, because it completely replaced GT1 & Progman. The main portion of ISIS that is used from the shop is called “ISTA”, which is often further divided into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s are available just about anyplace, including eBay for very 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, both in resident servers an internet-based versions. This makes it more difficult for non-dealer shops to work about the newer cars. You are likely to feel that considering that the GT1 was discontinued last year, you can just keep by using their for several more years before newer system became more available, however, BMW stayed a pace ahead! Whenever a car is programmed using the new ISTA/P, it upgrades the program past the level of what Program can recognize. That means, each car has become 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 which is pre-installed on that module can also be newer than what Program can recognize, which can stay away from the entire programming process, forcing the car to become programmed by ISTA/P.
Just what exactly does that mean for the BMW owner? As a result of the newer systems, many BMW owners can no longer repair the cars themselves. Many aftermarket shops can also be sending the cars to dealerships consequently. However, not all aftermarket shops have fallen behind. There is a limited number of BMW specialty shops that stick to the surface of manufacturer technology, to ensure no car is rejected! While looking for a spot to service your BMW, make sure they are able to do Every aspect of repair, including Diagnostics and CIP!
