Not simply has BMW electrical architecture changed throughout the last decade, but so has got the equipment to service them. The apparatus has changed, the interfaces have changed as well as the complexity of setup and make use of.
Early tools
Within the 1990’s, the viewers Tester One (GT1) was introduced. There was a few versions, like DIS Plus (stationary setup), though the GT1 is regarded as the common and it is what is going to be referenced here. The GT1 can be a portable device which contained a rechargeable battery. It has a touchscreen display screen for straightforward use. It contained software for Diagnosing as well as had software called TIS (Technical Information Display) the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So from your same tool, you may Diagnose the problem, lookup how to replace the component and then carry out the needed initializations for the new part. Two interfaces were used: EDIC (yellow interface) and also the OPS (orange interface). Later versions with the OPS were called OPPS, because they carried additional diagnostics for the Byteflite system and they were also yellow, but much wider as opposed to EDIC. Authentic GT1s take presctiption the portable touchscreen unit. There are lots of “cloned” units out there, adapted to operate on the PC. Either genuine or cloned, the interfaces work the same and repair by using an Ethernet port.
Later versions with the GT1 software removed CIP, and moved it into a separate computer (for storage), however accessible from your 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 quite a few bus simultaneously).
Third Generation equipment
Go forward to around 2008 once the Third Generation (3G) of apparatus premiered: ISIS. The valuables in ISIS are very large, that dedicated servers are set up with the dealership. A web-based version can be obtained for the aftermarket for a fee, called OSS. It may be bmw connected drive. With all the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS has a few parts, because it completely replaced GT1 & Progman. The key portion of ISIS utilized inside the shop is called “ISTA”, which is often further divided into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s are available just about anyplace, including eBay for cheap. BMW realized that the tool was easily cloned and sold worldwide. Many degrees of security are already put in the roll-out of ISIS to stop this, both in resident servers and online versions. This will make it harder for non-dealer shops to operate on the newer cars. One would think that because the GT1 was discontinued during 2009, you may just keep using that for many more years until the newer system became more available, however, BMW stayed a stride ahead! Whenever a car is programmed with the new ISTA/P, it upgrades the software program at night degree of what Program can recognize. Which means, once a car continues to be updated with ISTA/P, you cant ever use Progman into it again, rendering the “cloned” versions useless on that particular car. Also, each time a new module is installed, the software program which is pre-installed on that module can also be newer compared to what Program can recognize, which could steer clear of the entire programming process, forcing the automobile to get programmed by ISTA/P.
So what does which means that for the BMW owner? Because of the newer systems, many BMW owners cannot repair the cars themselves. Many aftermarket shops may also be sending the cars to dealerships because of this. However, its not all aftermarket shops have fallen behind. You can find a select few of BMW specialty shops that stay on surface of manufacturer technology, to ensure that no car is rejected! When looking for a place to service your BMW, be sure they’re able to do Every aspect of repair, including Diagnostics and CIP!
