Not simply has BMW electrical architecture changed over the past decade, but so contains the equipment to service them. The equipment has changed, the interfaces have changed plus the complexity of setup and employ.
Early tools
Back in the 1990’s, the gang Tester One (GT1) was introduced. There were several versions, like DIS Plus (stationary setup), however the GT1 is easily the most common and is after that be referenced here. The GT1 is often a portable device which contained a chargeable battery. It possesses a touchscreen display screen for easy 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 through the same tool, you may Diagnose the situation, lookup how to switch the component then perform the needed initializations for your new part. Two interfaces were used: EDIC (yellow interface) as well as the OPS (orange interface). Later versions with the OPS were called OPPS, because they carried additional diagnostics for your Byteflite system and they were also yellow, but much bigger compared to the EDIC. Authentic GT1s are on the portable touchscreen unit. There are numerous “cloned” units available, adapted to operate on a PC. Either genuine or cloned, the interfaces work precisely the same and correct through an Ethernet port.
Later versions with the GT1 software removed CIP, and moved it to a separate computer (for storage), but still 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 latest features like multiple car programming and dual channel programming for every car (DIAGBUS and MOST bus simultaneously).
Third Generation equipment
Skip ahead to about 2008 when the Third Generation (3G) of equipment was published: ISIS. The items in ISIS are extremely large, that hosting are installed in the dealership. A web-based version is accessible towards the aftermarket for a small fee, called OSS. It may be bmw ista. 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, because it completely replaced GT1 & Progman. The principle section of ISIS that is utilized from the shop is called “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 anywhere you want to, including eBay for cheap. BMW pointed out that the tool was easily cloned and sold worldwide. Many amounts of security happen to be put in the roll-out of ISIS to avoid this, in resident servers and online versions. Labeling will help you more difficult for non-dealer shops to operate for the newer cars. You are likely to feel that considering that the GT1 was discontinued in ’09, you may just keep using that for a lot of more years until the newer system became more available, however, BMW stayed one step ahead! Every time a car is programmed using the new ISTA/P, it upgrades the application past the amount of what Program can recognize. Meaning, each car has been updated with ISTA/P, you may never use Progman on it again, rendering the “cloned” versions useless on that particular car. Also, whenever a new module is installed, the application which is pre-installed on that module is additionally newer compared to what Program can recognize, that may stop the entire programming process, forcing the automobile being programmed by ISTA/P.
So what does this mean for your BMW owner? Due to the newer systems, many BMW owners still can’t repair the cars themselves. Many aftermarket shops are also sending the cars to dealerships therefore. However, don’t assume all aftermarket shops have fallen behind. You can find a limited number of BMW specialty shops that stick to top of manufacturer technology, to ensure no car is turned away! While looking for a spot to service your BMW, make certain they can do Every aspect of repair, including Diagnostics and CIP!
