Not merely has BMW electrical architecture changed over the past decade, but so contains the equipment to service them. The apparatus is different, the interfaces have changed along with the complexity of setup and make use of.
Early tools
Back in the 1990’s, the audience Tester One (GT1) was introduced. There was a number of versions, like DIS Plus (stationary setup), however the GT1 is regarded as the common which is after that be referenced here. The GT1 can be a portable device which contained a chargeable battery. It has a touchscreen display for straightforward use. It contained software for Diagnosing and also had software called TIS (Technical Information Display) which is Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So from your same tool, you could Diagnose the problem, lookup the way to switch the component after which perform the needed initializations for your new part. Two interfaces were chosen: EDIC (yellow interface) and the OPS (orange interface). Later versions with the OPS were called OPPS, simply because they carried additional diagnostics for your Byteflite system and so they were also yellow, but much wider than the EDIC. Authentic GT1s are saved to the portable touchscreen unit. There are numerous “cloned” units on the market, adapted to work with a PC. Either genuine or cloned, the interfaces work the identical and repair by using an Ethernet port.
Later versions with the GT1 software removed CIP, and moved it to some separate computer (for storage), but nevertheless accessible from your GT1. This new software was called Progman (short for Program Manager). This new software contained all 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
Go forward to around 2008 if the Third Generation (3G) of equipment was released: ISIS. The valuables in ISIS are extremely large, that hosting are installed at the dealership. A web based version is available to the aftermarket for a fee, called OSS. It can be bmw diagnostic software. Using the introduction of ISIS comes a whole new interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS includes a few parts, because it completely replaced GT1 & Progman. The main portion of ISIS that is utilized in the shop is called “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 available anywhere you want to, including eBay for cheap. BMW remarked that the tool was easily cloned and sold worldwide. Many degrees of security have already been place into the roll-out of ISIS to avoid this, both in resident servers and internet based versions. This will make it more difficult for non-dealer shops to work about the newer cars. One would believe considering that the GT1 was discontinued during 2009, you could keep using that for a number of more years before newer system became more available, however, BMW stayed a measure ahead! Every time a car is programmed together with the new ISTA/P, it upgrades the software program past the amount of what Program can recognize. Which means, once a car continues to be updated with ISTA/P, you may never use Progman on it again, rendering the “cloned” versions useless on that particular car. Also, when a new module is installed, the software program that is certainly pre-installed on that module can also be newer when compared with Program can recognize, which may steer clear of the entire programming process, forcing the car to become programmed by ISTA/P.
So what does which means that for your BMW owner? On account of the newer systems, many BMW owners can no longer repair the cars themselves. Many aftermarket shops can also be sending the cars to dealerships consequently. However, don’t assume all aftermarket shops have fallen behind. You can find a small selection of of BMW specialty shops that stay on the top of manufacturer technology, to ensure no car is averted! When looking for a location to service your BMW, make sure they are able to do Every aspect of repair, including Diagnostics and CIP!
