VDO inputs
There are three VDO inputs in the unit. The inputs have different functions, as the hardware
design allows for several VDO types.
VDO input 104: Oil pressure
VDO input 105: Cooling water temperature
VDO input 106: Fuel level sensor
VDO input 104
This VDO input is used for measuring the lubricating oil pressure.
