3.2.1. Electrical Vehicle Connector Pinning
This section describes the SCU vehicle connector pin properties and the connector pinning.
3.2.1.1. Pin Properties
Every connector pin is robust against short circuits to the supply voltage, to GND and to the
neighbour pins. The resistance of the short circuit may be as low as 0,1 Ohm.
An unwanted supply of the ECU by any other pins than the dedicated power supply pins is
impossible.
The ECU is robust against 5 kOhm shunt between adjacent pins of the vehicle connector
caused by dirt. No disturbance of the functionality.
3.2.1.2. Pin Assignment
Vehicle connector pin number assignment
Pin No
