Component description for the ME-SFI [ME] control unit - GF07.61-P-6000MCU

ENGINE 132.9 in MODEL 451.3/4 

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)
