A genuine BMW ISTA diagnostic scan or vehicle test determines the control units installed in the vehicle and their variants, as well as their special equipment.
Over the years BMW has used a number of different diagnostic hardware, here’s a look of current and previous hardware.
ICOM (Integration Communication Optical Module) – 3rd generation vehicle interface used by BMW dealers. It supports ADS, CAN, MOST and Ethernet communication to the vehicle and is compatible with BMW Standard Tools, E-Sys and ISTA. It’s composed of three parts (for cars)
ICOM A – Main piece and connects to the network and to the OBD port on the car
ICOM A2 – *** NEW *** ICOM A2 is a direct replacement for the ICOM A, it works exactly the same as the ICOM A and was released to overcome some of the design issues BMW felt existed with the ICOM A. It has a significantly more powerful processor, more storage capacity and a robust aluminum case will help to avoid damage when using in harsh environments.
