This function will read the PIN and CS for engine control units and transmission control units from the Immo III and Immo IV generation.

These are the CAN-Bus vehicles from about 2003 to 2014.

You can read the PIN/CS of the engine control units from the special functions > Engine Control Unit > Engine control unit Immo III/IV calculate CS or from Immo 3/4 parts adaptation > Engine control unit Immo III/IV calculate CS

You can read the PIN/CS of the transmission control unit from special functions > Immo 3/4 parts adaptation > Transmission control unit Immo 4 calculate CS

When the function is started, the connection to the control unit is established and the required data are read from there. It is necessary to have connection only with this module, not necessary to have the whole vehicle connected. I.e. this means that you can do this on the bench.

After the connection to the control unit is established, data are read and send to server.

When the calculation is finished, the PIN/CS will be displayed:

You can use later the PIN/CS for key-learning, or for adapting the ECU/TCU to the car

IMPORTANT: If the module (engine control unit or transmission) is not in its original state (e.g. the PIN/ CS were already changed with some after market tool), the calculated data might be wrong.

IMPORTANT: The function does not work for Immo V vehicles such as MQB, MLB, BCM2 vehicles.
