GF07.61-P-6000MQH ME-SFI [ME] Control Unit, Component Description
Component Identification
Location
The ME-SFI [ME] control unit is located in the front right wheel well.
Task
The ME-SFI [ME] control unit creates the engine control in electrical connection with the sensors and actors of engine 272 KE Hybrid. The following
systems and functions are controlled and coordinated by the ME-SFI [ME] control unit according to input signals:
-
Ignition system
-
Fuel supply
-
Injection control
-
Electronic accelerator
-
Diagnosis and fault storage
-
Drive authorization system and immobilizer
-
Regulated camshaft adjustment
-
Intake manifold changeover
-
Heat management
-
Alternator interface
-
Emission control
-
Power electronics cooling system
The ME-SFI [ME] control unit exchanges data to do this via the attached engine compartment-CAN (CAN C), drive train CAN (CAN C1) and hybrid
CAN (CAN L) with other control units which are integrated in the CAN network.
The ME-SFI [ME] control unit also acts as the interface (gateway) between the three CAN bus systems.
Input and output signals
The following input signals are evaluated by the engine control and issued in the respective output signals:
^
Direct input signals
^
Direct output signals
^
LIN signals
^
CAN input signals
^
CAN output signals
