Not simply has BMW electrical architecture changed during the last decade, but so has the equipment to service them. The gear changed, the interfaces have changed along with the complexity of setup and make use of.

Early tools

Within the 1990’s, the viewers Tester One (GT1) was introduced. There was a few versions, like DIS Plus (stationary setup), though the GT1 is regarded as the common and is also what will be referenced here. The GT1 can be a portable device which contained a chargeable battery. It features a touchscreen display for quick use. It contained software for Diagnosing and in addition 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 could Diagnose the problem, lookup the way to replace the component and then do the needed initializations for that new part. Two interfaces were used: EDIC (yellow interface) along with the OPS (orange interface). Later versions from the OPS were called OPPS, since they carried additional diagnostics for that Byteflite system and so they were also yellow, but larger as opposed to EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are lots of “cloned” units on the market, adapted to be effective over a PC. Either genuine or cloned, the interfaces work the same and repair via an Ethernet port.

Later versions from the GT1 software removed CIP, and moved it into a separate computer (for storage), but nonetheless 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 forward to around 2008 when the Third Generation (3G) of equipment was published: ISIS. The contents of ISIS are really large, that dedicated servers are installed in the dealership. An internet version is available towards the aftermarket for a fee, called OSS. It is usually bmw connected drive. Using the introduction of ISIS comes a new 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 primary portion of ISIS that is utilized from the shop is called “ISTA”, which can be further separated 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 inexpensive. BMW realized that the tool was easily cloned and sold worldwide. Many amounts of security happen to be put into the creation of ISIS in order to avoid this, in both resident servers and online versions. It is then more difficult for non-dealer shops to be effective on the newer cars. One would feel that since GT1 was discontinued during 2009, you could just keep by using their for a lot of more years before the newer system became more available, however, BMW stayed one step ahead! Each time a car is programmed with all the new ISTA/P, it upgrades the software program beyond the degree of what Program can recognize. Which means, each car has become updated with ISTA/P, you’ll 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 that is certainly pre-installed with that module is additionally newer than Program can recognize, which may steer clear of the entire programming process, forcing the car to become programmed by ISTA/P.

Just what exactly does this mean for that BMW owner? On account of the newer systems, many BMW owners still can’t repair the cars themselves. Many aftermarket shops are also sending the cars to dealerships as a result. However, its not all aftermarket shops have fallen behind. There are a select few of BMW specialty shops that remain on the surface of manufacturer technology, to ensure no car is averted! When looking for a location to service your BMW, make sure they are able to do Every aspect of repair, including Diagnostics and CIP!
