Not just 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 plus the complexity of setup and use.
Early tools
In the 1990’s, the gang Tester One (GT1) was introduced. There have been a couple of versions, like DIS Plus (stationary setup), though the GT1 is regarded as the common which is what’s going to be referenced here. The GT1 is really a portable device which contained a rechargeable battery. It provides a touchscreen technology for quick use. It contained software for Diagnosing plus 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 through the same tool, you can Diagnose the issue, look up how you can switch the component and after that perform the needed initializations to the new part. Two interfaces were used: EDIC (yellow interface) along with the OPS (orange interface). Later versions in the OPS were called OPPS, simply because they carried additional diagnostics to the Byteflite system and they also were also yellow, but larger compared to the EDIC. Authentic GT1s are saved to the portable touchscreen unit. There are lots of “cloned” units on the market, adapted to work on a PC. Either genuine or cloned, the interfaces work the same and repair via an Ethernet port.
Later versions in the GT1 software removed CIP, and moved it into a separate computer (for storage), however accessible through the GT1. This new software was called Progman (short for Program Manager). This new software contained all of the CIP functions and added extra features like multiple car programming and dual channel programming per car (DIAGBUS and a lot bus simultaneously).
Third Generation equipment
Skip ahead to around 2008 once the Third Generation (3G) of equipment was published: ISIS. The valuables in ISIS are very large, that server colocation are set up on the dealership. An online version can be obtained towards the aftermarket for a small charge, called OSS. It could be itoolradar. With all the introduction of ISIS comes a new interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS has a few parts, since it completely replaced GT1 & Progman. The primary portion of ISIS utilized inside the shop is named “ISTA”, which can be further divided into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s is available just about anywhere, including eBay for inexpensive. BMW realized that the tool was easily cloned and sold worldwide. Many levels of security happen to be put in the roll-out of ISIS in order to avoid this, in the resident servers and internet based versions. This makes it more difficult for non-dealer shops to work for the newer cars. One would feel that considering that the GT1 was discontinued in 2009, you can just keep using that for many more years before newer system became more available, however, BMW stayed a stride ahead! When a car is programmed together with the new ISTA/P, it upgrades the software program past the amount of what Program can recognize. Which means, when a car has become updated with ISTA/P, you’ll never use Progman onto it again, rendering the “cloned” versions useless on that particular car. Also, every time a new module is installed, the software program that is certainly pre-installed on that module is also newer than Program can recognize, which could steer clear of the entire programming process, forcing the vehicle to get programmed by ISTA/P.
Just what exactly does which means that to the BMW owner? As a result 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 consequently. However, don’t assume all aftermarket shops have fallen behind. There are a small number of of BMW specialty shops that remain on the top of manufacturer technology, to ensure that no car is rejected! When looking for a spot to service your BMW, make certain they are able to do ALL aspects of repair, including Diagnostics and CIP!
