Not simply has BMW electrical architecture changed over the past decade, but so contains the equipment to service them. The device is different, the interfaces have changed as well as the complexity of setup and employ.

Early tools

In the 1990’s, the gang Tester One (GT1) was introduced. There were a number of versions, like DIS Plus (stationary setup), nevertheless the GT1 is among the most common and is also after that be referenced here. The GT1 is a portable device which contained a chargeable battery. It provides a touchscreen display screen for straightforward use. It contained software for Diagnosing and also had software called TIS (Technical Information Display) the actual Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So from the same tool, you may Diagnose the situation, look up the way to switch the component after which perform needed initializations for your new part. Two interfaces were utilized: EDIC (yellow interface) and also the OPS (orange interface). Later versions from the OPS were called OPPS, simply because they carried additional diagnostics for your Byteflite system and so they were also yellow, but much larger as opposed to EDIC. Authentic GT1s are on the portable touchscreen unit. There are many “cloned” units out there, adapted to be effective over a PC. Either genuine or cloned, the interfaces work precisely the same and fasten by using 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 every one of the CIP functions and added new features like multiple car programming and dual channel programming for each car (DIAGBUS and many bus simultaneously).

Third Generation equipment

Skip ahead about 2008 in the event the Third Generation (3G) of equipment was published: ISIS. The belongings in ISIS are really large, that hosting are set up at the dealership. An internet version is available towards the aftermarket for a fee, called OSS. It can be bmw navigation update. Using the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS is made up of few parts, as it completely replaced GT1 & Progman. The key a part of ISIS that is used in the shop is named “ISTA”, that may be further divided into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s are available almost anyplace, including eBay for inexpensive. BMW realized that the tool was easily cloned and sold worldwide. Many numbers of security happen to be placed into the development of ISIS to stop this, in the resident servers and online versions. Labeling will help you much harder for non-dealer shops to be effective for the newer cars. One would believe that because the GT1 was discontinued in ’09, you may keep by using their for several more years until the newer system became more available, however, BMW stayed a measure ahead! Whenever a car is programmed together with the new ISTA/P, it upgrades the software past the degree of what Program can recognize. That means, after a car continues to be updated with ISTA/P, you may never use Progman into it again, rendering the “cloned” versions useless on that particular car. Also, each time a new module is installed, the software that’s pre-installed on that module can be newer than Program can recognize, which can stay away from the entire programming process, forcing the auto to get programmed by ISTA/P.

Just what exactly does that mean for your BMW owner? Due to the newer systems, many BMW owners still can’t repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships because of this. However, not every aftermarket shops have fallen behind. You can find a small number of of BMW specialty shops that remain on surface of manufacturer technology, to ensure no car is averted! When looking for an area to service your BMW, make certain they are able to do Every aspect of repair, including Diagnostics and CIP!
