BMW Service Technology – The Development of Diagnostic Gear

Posted on by

Not just has BMW electrical architecture changed during the last decade, but so gets the equipment to service them. The gear has evolved, the interfaces have changed as well as the complexity of setup and use.

Early tools

Back in the 1990’s, the viewers Tester One (GT1) was introduced. There were several versions, like DIS Plus (stationary setup), even so the GT1 is easily the most common and it is what will be referenced here. The GT1 can be a portable device which contained a chargeable battery. It features a touchscreen display for straightforward use. It contained software for Diagnosing and in addition had software called TIS (Technical Information Display) which is the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So in the same tool, you may Diagnose the situation, look up the best way to switch the component then carry out the needed initializations for the new part. Two interfaces were used: EDIC (yellow interface) and the OPS (orange interface). Later versions of the OPS were called OPPS, given that they carried additional diagnostics for the Byteflite system plus they were also yellow, but much larger compared to the EDIC. Authentic GT1s are saved to the portable touchscreen unit. There are many “cloned” units out there, adapted to be effective with a PC. Either genuine or cloned, the interfaces work the identical and repair via an Ethernet port.

Later versions of the GT1 software removed CIP, and moved it into a separate computer (for storage), however accessible in the GT1. This new software was called Progman (short for Program Manager). This new software contained each of the CIP functions and added latest features like multiple car programming and dual channel programming for every car (DIAGBUS and a lot bus simultaneously).

Third Generation equipment

Fast forward to about 2008 in the event the Third Generation (3G) of apparatus was released: ISIS. The valuables in ISIS are so large, that dedicated servers are installed with the dealership. An internet version is accessible on the aftermarket for a small fee, called OSS. It is usually code bmw m logo. With all the introduction of ISIS comes a new interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS has a few parts, mainly because it completely replaced GT1 & Progman. The primary part of ISIS that is used from the shop is termed “ISTA”, which is often further divided into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s is available just about anyplace, including eBay for cheap. BMW pointed out that the tool was easily cloned and sold worldwide. Many numbers of security have been put in the creation of ISIS to prevent this, in resident servers and internet based versions. This will make it harder for non-dealer shops to be effective around the newer cars. You are likely to believe that considering that the GT1 was discontinued in ’09, you may just keep using for a lot of more years until the newer system became more available, however, BMW stayed a pace ahead! Whenever a car is programmed together with the new ISTA/P, it upgrades the software at night amount of what Program can recognize. That means, when a car may be updated with ISTA/P, you cant ever use Progman into it again, rendering the “cloned” versions useless on that particular car. Also, every time a new module is installed, the software that is certainly pre-installed on that module can be newer than Program can recognize, which could pun intended, the entire programming process, forcing the automobile to get programmed by ISTA/P.

What exactly does that mean for the BMW owner? Due to the newer systems, many BMW owners can’t repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships therefore. However, not all aftermarket shops have fallen behind. You can find a select few of BMW specialty shops that remain on surface of manufacturer technology, in order that no car is turned away! While searching for an area to service your BMW, be sure they could do Every aspect of repair, including Diagnostics and CIP!
