Not merely has BMW electrical architecture changed over the past decade, but so contains the equipment to service them. The gear has changed, the interfaces have changed as well as the complexity of setup and use.
Early tools
Back in the 1990’s, the audience Tester One (GT1) was introduced. There was a few versions, like DIS Plus (stationary setup), however the GT1 is among the most common which is what will be referenced here. The GT1 is often a portable device which contained a rechargeable battery. It possesses a touchscreen display for simple use. It contained software for Diagnosing and in addition 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 in the same tool, you might Diagnose the problem, look up how you can switch the component and then do the needed initializations for your new part. Two interfaces were utilised: EDIC (yellow interface) along with the OPS (orange interface). Later versions from the OPS were called OPPS, since they carried additional diagnostics for your Byteflite system and so they were also yellow, but much bigger as opposed to EDIC. Authentic GT1s are on the portable touchscreen unit. There are lots of “cloned” units available, adapted to function with a PC. Either genuine or cloned, the interfaces work precisely the same and repair with an Ethernet port.
Later versions from the GT1 software removed CIP, and moved it to a separate computer (for storage), but still accessible in the GT1. This new software was called Progman (short for Program Manager). This new software contained every one of the CIP functions and added additional features like multiple car programming and dual channel programming for every car (DIAGBUS and many bus simultaneously).
Third Generation equipment
Fast forward to around 2008 in the event the Third Generation (3G) of equipment was launched: ISIS. The belongings in ISIS are so large, that dedicated servers are set up on the dealership. An online version can be obtained to the aftermarket for a small charge, called OSS. It may be bmw idrive coding. Using the introduction of ISIS comes a whole new interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS is made up of few parts, mainly because it completely replaced GT1 & Progman. The principle section of ISIS that is used within the shop is named “ISTA”, which is often further categorised into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s is available just about anyplace, including eBay for really cheap. BMW realized that the tool was easily cloned and sold worldwide. Many amounts of security happen to be placed into the creation of ISIS to prevent this, in both resident servers and internet-based versions. This makes it more difficult for non-dealer shops to function for the newer cars. You are likely to believe that since GT1 was discontinued in 2009, you might just keep using for several more years until the newer system became more available, however, BMW stayed a measure ahead! When a car is programmed together with the new ISTA/P, it upgrades the software at night level of what Program can recognize. This means, once a car continues to be updated with ISTA/P, you’ll never use Progman on it again, rendering the “cloned” versions useless on that particular car. Also, each time a new module is installed, the software which is pre-installed on that module can be newer than what Program can recognize, which could stop the entire programming process, forcing the automobile to get programmed by ISTA/P.
So what does this mean for your BMW owner? Due to the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships as a result. However, its not all aftermarket shops have fallen behind. You can find a small selection of of BMW specialty shops that remain on surface of manufacturer technology, so that no car is turned away! While looking for a place to service your BMW, be sure they are able to do ALL aspects of repair, including Diagnostics and CIP!
