EMS 2
Inputs/Outputs
5 Inputs/Outputs
5.1 Inputs
The following table provides an overview of the possible outputs at the EMS 2.
An example of pin assignment (engine 1015, EMS and MVS) is shown in Chapter 11.8.
The EMS 2 control unit can be configured in the factory in such a manner that further input signals can be
read via the CAN bus.
No. Pin GND Designation can be connected measured Especially suitable for
