Not just has BMW electrical architecture changed during the last decade, but so gets the equipment to service them. The device has changed, the interfaces have changed and also the complexity of setup and use.

Early tools

Within the 1990’s, the Group Tester One (GT1) was introduced. There have been a number of versions, like DIS Plus (stationary setup), however the GT1 is easily the most common and is what will be referenced here. The GT1 is really a portable device which contained a rechargeable battery. It features a touchscreen technology for quick 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 issue, research how to replace the component then do the needed initializations for your new part. Two interfaces were chosen: EDIC (yellow interface) along with the OPS (orange interface). Later versions from the OPS were called OPPS, given that they carried additional diagnostics for your Byteflite system and they were also yellow, but larger compared to EDIC. Authentic GT1s are saved to the portable touchscreen unit. There are several “cloned” units out there, adapted to be effective over a PC. Either genuine or cloned, the interfaces work exactly the same and repair via an Ethernet port.

Later versions from the GT1 software removed CIP, and moved it into 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 all of the CIP functions and added new features like multiple car programming and dual channel programming for each and every car (DIAGBUS and a lot bus simultaneously).

Third Generation equipment

Skip forward to about 2008 in the event the Third Generation (3G) of apparatus premiered: ISIS. The belongings in ISIS are really large, that hosting are set up at the dealership. An online version is available on the aftermarket for a fee, called OSS. It can be bmw esys coding. With the introduction of ISIS comes a whole new interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS has a few parts, as it completely replaced GT1 & Progman. The key section of ISIS which is used inside the shop is called “ISTA”, which may be further categorised into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s is available just about anyplace, including eBay for inexpensive. BMW realized that the tool was easily cloned and sold worldwide. Many levels of security are already put in the growth of ISIS to avoid this, both in resident servers and internet based versions. This makes it harder for non-dealer shops to be effective on the newer cars. One could feel that because the GT1 was discontinued last year, you could keep using for many more years until the newer system became more available, however, BMW stayed one step ahead! Each time a car is programmed with all the new ISTA/P, it upgrades the software program past the degree of what Program can recognize. This means, each car may be updated with ISTA/P, you can NEVER use Progman about it again, rendering the “cloned” versions useless on that particular car. Also, when a new module is installed, the software program that’s pre-installed on that module is additionally newer when compared with Program can recognize, that may steer clear of the entire programming process, forcing the automobile to get programmed by ISTA/P.

Just what exactly does which means that for your BMW owner? Because of the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops can also be sending the cars to dealerships consequently. However, its not all aftermarket shops have fallen behind. You can find a select few of BMW specialty shops that stick to the surface of manufacturer technology, to ensure no car is beaten down! While looking for a location to service your BMW, be sure they are able to do ALL aspects of repair, including Diagnostics and CIP!
