BMW Service Technology – The Development of Diagnostic Tools

Not just has BMW electrical architecture changed over the past decade, but so has the equipment to service them. The apparatus has changed, the interfaces have changed plus the complexity of setup and employ.

Early tools

Within the 1990’s, the viewers Tester One (GT1) was introduced. There have been a couple of versions, like DIS Plus (stationary setup), though the GT1 is easily the most common which is what will be referenced here. The GT1 is a portable device which contained a rechargeable battery. It has a touchscreen display for quick use. It contained software for Diagnosing as well as 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 from the same tool, you could Diagnose the issue, look up how to replace the component and then perform the needed initializations for the new part. Two interfaces were utilized: EDIC (yellow interface) as well as the OPS (orange interface). Later versions of the OPS were called OPPS, simply because they carried additional diagnostics for the Byteflite system and they also were also yellow, but much wider as opposed to EDIC. Authentic GT1s are on the portable touchscreen unit. There are lots of “cloned” units out there, adapted to operate over a PC. Either genuine or cloned, the interfaces work the identical and fasten by using an Ethernet port.

Later versions of the GT1 software removed CIP, and moved it with a separate computer (for storage), but nevertheless 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 extra features like multiple car programming and dual channel programming for each and every car (DIAGBUS and quite a few bus simultaneously).

Third Generation equipment

Skip forward to about 2008 when the Third Generation (3G) of kit was released: ISIS. The items in ISIS are very large, that web site hosting are installed with the dealership. A web-based version can be acquired towards the aftermarket for a fee, called OSS. It can be bmw acceleration video. Using the introduction of ISIS comes a brand new interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS consists of a few parts, as it completely replaced GT1 & Progman. The principle portion of ISIS that is utilized within 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 are available almost anyplace, including eBay for inexpensive. BMW remarked that the tool was easily cloned and sold worldwide. Many numbers of security have already been put into the creation of ISIS in order to avoid this, both in resident servers and online versions. This makes it much harder for non-dealer shops to operate on the newer cars. One would believe since the GT1 was discontinued in ’09, you could keep by using their for a number of more years before newer system became more available, however, BMW stayed a measure ahead! Each time a car is programmed with all the new ISTA/P, it upgrades the software program beyond the level of what Program can recognize. This means, after a car may be updated with ISTA/P, you cant ever use Progman onto it again, rendering the “cloned” versions useless with that particular car. Also, whenever a new module is installed, the software program that is certainly pre-installed with that module can also be newer than what Program can recognize, which could steer clear of the entire programming process, forcing the car to be programmed by ISTA/P.

What exactly does this mean for the BMW owner? Because of the newer systems, many BMW owners still can’t repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships therefore. However, its not all aftermarket shops have fallen behind. There is a select few of BMW specialty shops that stick to the top of manufacturer technology, to ensure no car is rejected! While looking for a place to service your BMW, be sure they could do Every aspect of repair, including Diagnostics and CIP!
