GF07.61-P-6000MCU Component Description For The ME-SFI [ME] Control Unit







N3/10 ME-SFI [ME] control unit

Location
The ME-SFI [ME] control unit is located in the trunk, behind the right side paneling.

Task
The ME-SFI [ME] control unit controls, monitors and coordinates the entire engine control.

Function
The ME-SFI [ME] control unit is a subscriber on the Control Area Network (data bus/CAN bus) (CAN) and controls the following systems:
^ Fuel supply
^ Injection control
^ Secondary air injection
^ Lambda control
^ Ignition system
^ Immobilizer

Communication with the following components takes place via the CAN:
^ Instrument cluster (A1)
^ Restraint systems control unit (N2/7)
^ SAM control unit (N10/10)
^ Automated manual transmission control unit (N15/6)
^ Heater/air conditioning operating unit (N23) (for code (I01) Air conditioning Plus)
^ ESP control unit (N47-5)
^ Steering assist control unit (N68) (with code (V26) Power steering, EPS (FFO))

The following components are read in directly by the ME-SFI ME] control unit:
^ Knock sensor (A16)
^ Tank pressure sensor (B4/3)
^ Camshaft Hall sensor (B6/1)
^ Coolant temperature sensor (B11/4)
^ Intake manifold pressure sensor (B28)
^ Accelerator pedal sensor (B37)
^ Alternator (G2)
^ O2 sensor downstream of TWC (G3/1)
^ O2 sensor upstream of TWC (G3/2)
^ Crankshaft position sensor (L5)
^ Throttle valve actuator (M16/6)
^ Oil pressure switch (S41/1)
^ Fuel level sensor (M3/3b1)

The following components are actuated directly by the ME-SFI [ME] control unit:
^ Generator

^ Heating O2 sensor upstream of TWC
^ Secondary air injection pump relay (K64)
^ Throttle valve actuator
^ Cylinder 1 ignition coil (T1/1)
^ Cylinder 2 ignition coil (T1/2)
^ Cylinder 3 ignition coil (T1/3)
^ Secondary air injection pump switchover valve (Y32)
^ Adjustable camshaft timing solenoid (Y49)
^ External air shut-off valve (Y50)
^ Tank vent valve (Y58)
^ Cylinder 1 fuel injection valve (Y62/1)
^ Cylinder 2 fuel injection valve (Y62/2)
^ Cylinder 3 fuel injection valve (Y62/3)
