DFI control module position/task/function

16.3.95

Task

Controlling the systems and functions in line with the analysis of the input signals:
 Quantity control
 Start of injection control
 Emission control
 Boost pressure control
 Cruise control (AT only)

 Data transfer through CAN data bus

 Diagnosis, monitoring of inputs/outputs, plausibility check, fault memory

 Producing substitute value in event of signal failure

 Starter protection as of 03/97
 Glow time control
 Drive authorization system
 Version coding

Function

The DFI control module (N3/8) is supplied with voltage (circuit 87 unfused) by the relay module (K40, up to 02/97) or by the fuse and relay module (K40/4, as of 03/97). It detects the input signals and controls the outputs in line with the operating conditions. A pressure sensor for atmospheric pressure is integrated in the control module.
