Not simply has BMW electrical architecture changed over the last decade, but so has the equipment to service them. The device is different, the interfaces have changed as well as the complexity of setup and use.
Early tools
During the 1990’s, the audience Tester One (GT1) was introduced. There were several versions, like DIS Plus (stationary setup), however the GT1 is regarded as the common and is after that be referenced here. The GT1 is often a portable device which contained a rechargeable battery. It provides a touchscreen display screen for straightforward 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 through the same tool, you could Diagnose the problem, lookup the way to switch the component and then perform the needed initializations for your new part. Two interfaces were chosen: EDIC (yellow interface) and the OPS (orange interface). Later versions in the OPS were called OPPS, simply because they carried additional diagnostics for your Byteflite system and so they were also yellow, but much wider compared to EDIC. Authentic GT1s are on the portable touchscreen unit. There are lots of “cloned” units out there, adapted to be effective over a PC. Either genuine or cloned, the interfaces work the same and correct with an Ethernet port.
Later versions in the GT1 software removed CIP, and moved it with a separate computer (for storage), but nevertheless accessible through 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 MOST bus simultaneously).
Third Generation equipment
Go forward to around 2008 once the Third Generation (3G) of equipment was released: ISIS. The valuables in ISIS are so large, that dedicated servers are set up at the dealership. A web-based version can be obtained towards the aftermarket for a small charge, called OSS. It is usually itoolradar. Using the introduction of ISIS comes a new interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS includes a few parts, as it completely replaced GT1 & Progman. The key section of ISIS that is utilized from the shop is named “ISTA”, that may be further separated into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s can be found almost anyplace, including eBay for really cheap. BMW remarked that the tool was easily cloned and sold worldwide. Many amounts of security have already been put in the roll-out of ISIS to stop this, in both resident servers an internet-based versions. This makes it harder for non-dealer shops to be effective on the newer cars. You might believe that since GT1 was discontinued during 2009, you could keep using for several more years before newer system became more available, however, BMW stayed a measure ahead! Every time a car is programmed together with the new ISTA/P, it upgrades the application after dark a higher level what Program can recognize. Meaning, when a car has been updated with ISTA/P, you cant ever use Progman onto it again, rendering the “cloned” versions useless with that particular car. Also, every time a new module is installed, the application that is certainly pre-installed with that module is additionally newer than what Program can recognize, which can stop the entire programming process, forcing the vehicle to get programmed by ISTA/P.
Just what exactly does that mean for your BMW owner? Because of the newer systems, many BMW owners can no longer repair the cars themselves. Many aftermarket shops can also be sending the cars to dealerships because of this. However, not every aftermarket shops have fallen behind. There are a select few of BMW specialty shops that stick to top of manufacturer technology, to ensure no car is rejected! While searching for an area to service your BMW, be sure they could do Every aspect of repair, including Diagnostics and CIP!
