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

Early tools

Back in the 1990’s, the viewers Tester One (GT1) was introduced. There were a number of versions, like DIS Plus (stationary setup), however the GT1 is regarded as the common and it is what is going to be referenced here. The GT1 is really a portable device which contained a chargeable battery. It possesses a touchscreen display for quick use. It contained software for Diagnosing plus had software called TIS (Technical Information Display) which is Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So in the same tool, you might Diagnose the problem, research how to switch the component after which carry out the needed initializations for the new part. Two interfaces were chosen: EDIC (yellow interface) as well as the OPS (orange interface). Later versions from the OPS were called OPPS, simply because they carried additional diagnostics for the Byteflite system and they were also yellow, but much wider than the EDIC. Authentic GT1s take presctiption the portable touchscreen unit. There are numerous “cloned” units available, adapted to work on a PC. Either genuine or cloned, the interfaces work precisely the same and correct by using an Ethernet port.

Later versions from the GT1 software removed CIP, and moved it to some separate computer (for storage), but nonetheless 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 new features like multiple car programming and dual channel programming per car (DIAGBUS and quite a few bus simultaneously).

Third Generation equipment

Go forward to around 2008 once the Third Generation (3G) of kit premiered: ISIS. The valuables in ISIS are so large, that dedicated servers are set up in the dealership. An internet version is accessible on the aftermarket for their fee, called OSS. It may be bmw esys coding. With all the introduction of ISIS comes a brand new interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS includes a few parts, because it completely replaced GT1 & Progman. The primary portion of ISIS that is utilized within the shop is termed “ISTA”, which is often further broken down into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s is available just about anywhere, including eBay for inexpensive. BMW remarked that the tool was easily cloned and sold worldwide. Many amounts of security happen to be put into the growth of ISIS to avoid this, in both resident servers and internet-based versions. This will make it harder for non-dealer shops to work on the newer cars. You might feel that since the GT1 was discontinued last year, you might just keep using that for a number of more years before the newer system became more available, however, BMW stayed a stride ahead! Each time a car is programmed using the new ISTA/P, it upgrades the software program after dark amount of what Program can recognize. This means, when a car has become updated with ISTA/P, you’ll never use Progman into it again, rendering the “cloned” versions useless with that particular car. Also, whenever a new module is installed, the software program that’s pre-installed with that module can also be newer than Program can recognize, which may stop the entire programming process, forcing the car to get programmed by ISTA/P.

What exactly does that mean for the 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 as a result. However, not every aftermarket shops have fallen behind. You can find a limited number of BMW specialty shops that remain on surface of manufacturer technology, so that no car is averted! When searching for a spot to service your BMW, be sure they’re able to do ALL aspects of repair, including Diagnostics and CIP!
