Not only has BMW electrical architecture changed during the last decade, but so has got the equipment to service them. The equipment has changed, the interfaces have changed as well as the complexity of setup and employ.
Early tools
In the 1990’s, the gang Tester One (GT1) was introduced. There was a number of versions, like DIS Plus (stationary setup), even so the GT1 is the most common which is what is going to be referenced here. The GT1 is a portable device which contained a chargeable battery. It provides a touchscreen technology for easy use. It contained software for Diagnosing plus had software called TIS (Technical Information Display) the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So through the same tool, you can Diagnose the situation, research the way to switch the component then perform the needed initializations to the new part. Two interfaces were used: EDIC (yellow interface) and the OPS (orange interface). Later versions of the OPS were called OPPS, given that they carried additional diagnostics to the Byteflite system and they were also yellow, but larger compared to EDIC. Authentic GT1s take presctiption the portable touchscreen unit. There are many “cloned” units on the market, adapted to function on the PC. Either genuine or cloned, the interfaces work precisely the same and connect with an Ethernet port.
Later versions of the GT1 software removed CIP, and moved it to some 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 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
Go forward to around 2008 once the Third Generation (3G) of it technology premiered: ISIS. The belongings in ISIS are really large, that server colocation are set up on the dealership. An online version is accessible for the aftermarket for their fee, called OSS. It is usually bmw software update. With all the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS consists of a few parts, because it completely replaced GT1 & Progman. The key portion of ISIS that is used in the shop is called “ISTA”, which may be further broken down into a double edged sword: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s are available just about anyplace, including eBay for inexpensive. BMW remarked that the tool was easily cloned and sold worldwide. Many numbers of security have already been place into the development of ISIS to stop this, both in resident servers and internet-based versions. It is then more difficult for non-dealer shops to function for the newer cars. You are likely to feel that since the GT1 was discontinued in ’09, you can keep by using their for a number of more years prior to the newer system became more available, however, BMW stayed a measure ahead! When a car is programmed using the new ISTA/P, it upgrades the software program beyond the degree of what Program can recognize. This means, when a car has become updated with ISTA/P, you can NEVER use Progman about it again, rendering the “cloned” versions useless on that particular car. Also, whenever a new module is installed, the software program which is pre-installed on that module is also newer than Program can recognize, that may steer clear of the entire programming process, forcing the auto to be programmed by ISTA/P.
Precisely what does that mean to the BMW owner? Due to the newer systems, many BMW owners can’t repair the cars themselves. Many aftermarket shops can also be sending the cars to dealerships because of this. However, not all aftermarket shops have fallen behind. There’s a select few of BMW specialty shops that stay with the surface of manufacturer technology, to ensure that no car is turned away! When searching for a location to service your BMW, make certain they’re able to do Every aspect of repair, including Diagnostics and CIP!
