Not merely has BMW electrical architecture changed over the past decade, but so has got the equipment to service them. The apparatus has evolved, the interfaces have changed and also the complexity of setup and employ.
Early tools
Within the 1990’s, the audience 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 it is what’s going to 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 the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So from the same tool, you can Diagnose the situation, look up the best way to switch the component after which do the needed initializations to the new part. Two interfaces were utilised: EDIC (yellow interface) and also the OPS (orange interface). Later versions in the OPS were called OPPS, given that they carried additional diagnostics to the Byteflite system and they were also yellow, but much wider compared to the EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are several “cloned” units out there, adapted to function over a PC. Either genuine or cloned, the interfaces work the same and correct via an Ethernet port.
Later versions in the GT1 software removed CIP, and moved it into a separate computer (for storage), however accessible from the GT1. This new software was called Progman (short for Program Manager). This new software contained all the CIP functions and added extra 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 if the Third Generation (3G) of it technology was launched: ISIS. The contents of ISIS are so large, that dedicated servers are set up with the dealership. A web-based version can be obtained towards the aftermarket for a small fee, called OSS. It is usually bmw acceleration video. Using the introduction of ISIS comes a new interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS has a few parts, mainly because it completely replaced GT1 & Progman. The main part of ISIS which is used from the shop is termed “ISTA”, which may be further broken down into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s is found anywhere you want to, including eBay for very cheap. BMW remarked that the tool was easily cloned and sold worldwide. Many levels of security are already put in the development of ISIS in order to avoid this, in the resident servers and internet based versions. Labeling will help you more difficult for non-dealer shops to function on the newer cars. One could believe that considering that the GT1 was discontinued in 2009, you can just keep by using their for a number of more years prior to the newer system became more available, however, BMW stayed a measure ahead! Every time a car is programmed with all the new ISTA/P, it upgrades the program past the amount of what Program can recognize. Which means, when a car continues to be updated with ISTA/P, you may never use Progman into it again, rendering the “cloned” versions useless with that particular car. Also, whenever a new module is installed, the program which is pre-installed with that module is also newer than what Program can recognize, which could pun intended, the entire programming process, forcing the vehicle being programmed by ISTA/P.
Just what exactly does which means that to the BMW owner? Because of the newer systems, many BMW owners can no longer repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships as a result. However, don’t assume all aftermarket shops have fallen behind. There are a select few of BMW specialty shops that stay with top of manufacturer technology, to ensure no car is averted! While searching for a location to service your BMW, make certain they could do Every aspect of repair, including Diagnostics and CIP!
