Not only has BMW electrical architecture changed over the last decade, but so has the equipment to service them. The equipment is different, the interfaces have changed and also the complexity of setup and make use of.
Early tools
Back in the 1990’s, the gang Tester One (GT1) was introduced. There was several versions, like DIS Plus (stationary setup), however the GT1 is easily the most common and is also what will be referenced here. The GT1 is a portable device which contained a chargeable battery. It provides a touchscreen display for easy use. It contained software for Diagnosing and also 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 might Diagnose the situation, look up how to replace the component after which perform needed initializations for that new part. Two interfaces were used: EDIC (yellow interface) as well as the OPS (orange interface). Later versions with the OPS were called OPPS, simply because they carried additional diagnostics for that Byteflite system and they were also yellow, but larger than the EDIC. Authentic GT1s take presctiption the portable touchscreen unit. There are numerous “cloned” units out there, adapted to operate on the PC. Either genuine or cloned, the interfaces work the identical and fasten via an Ethernet port.
Later versions from the GT1 software removed CIP, and moved it to some separate computer (for storage), but nevertheless accessible from your 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 for each and every car (DIAGBUS and MOST bus simultaneously).
Third Generation equipment
Go forward about 2008 once the Third Generation (3G) of equipment was launched: ISIS. The valuables in ISIS are extremely large, that dedicated servers are installed on the dealership. An online version is available towards the aftermarket for a small charge, called OSS. It could be found at bmw rheingold 40122 standalone psdzdata 4.01 22. With all 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, since it completely replaced GT1 & Progman. The primary section of ISIS that is utilized inside the shop is named “ISTA”, which can be further broken down into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s is found just about anywhere, including eBay for really cheap. BMW remarked that the tool was easily cloned and sold worldwide. Many degrees of security have already been placed into the creation of ISIS to stop this, in the resident servers and online versions. It is then harder for non-dealer shops to work on the newer cars. One could think that since the GT1 was discontinued in ’09, you can keep by using their for several 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 past the degree of what Program can recognize. Meaning, when a car may be updated with ISTA/P, you’ll never use Progman onto it again, rendering the “cloned” versions useless on that particular car. Also, whenever a new module is installed, the program which is pre-installed with that module is also newer than what Program can recognize, which may steer clear of the entire programming process, forcing the vehicle to become programmed by ISTA/P.
So what does which means that for your BMW owner? Due to the newer systems, many BMW owners can’t repair the cars themselves. Many aftermarket shops may also be sending the cars to dealerships consequently. However, don’t assume all aftermarket shops have fallen behind. There’s a limited number of BMW specialty shops that stick to the surface of manufacturer technology, to ensure that no car is averted! When looking for a location to service your BMW, ensure they can do ALL aspects of repair, including Diagnostics and CIP!
One such shop is Auto Specialties of Lake Norman: Auto Specialties of Lake Norman. Should you be looking at a potential shops website, search for signs they will have the most recent equipment. BMW Repair Shops that can’t “do it all” can often cause increased time and cost after they discover everything has been incorrectly diagnosed or parts installed now need programmed or initialized.
