The above picture shows the pin assignment of the control unit on vehicle side. The pin designation is indicated to the right of the pin number [red]. The function assigned to this particular pin is depicted next to it.
Variable inputs allow their function to be selected via the data record, i.e. the data record specifies which function is activated at which pin.
The control unit features inputs for switches that can be connected to ground (ELxx) and to +24 V (EHxx).
For a switch to ground, the signal is usually active if a ground signal is on, and inactive if the input is open. This behaviour can be programmed in the data record of the control unit.
This behaviour can be inverted via settings in the data record.
For control units with serial numbers higher than 837.
Apply menu item A "Read identification and pin assignment" to display a table of the current connector pin assignment of vehicle and transmission as specified in the record.
Unlike the screen of DIWAgnosis, which shows the vehicle-specific pin assignment at the variable inputs and outputs, the following table presents the possible pin assignment. The vehicle-specific pin assignment is defined together with the vehicle manufacturer in the development phase and implemented in the data record.
