Test sequence



- Switch off ignition.



- Disconnect coupling M at component N3/10 (ME-SFI [ME] control unit).



- Measure resistance with multimeter between sockets (M.75) 75 and (M.74) 74 of the 126-pole socket box tester.



Specified value



- Resistor[1...10]ohms



Question



- Is the measurement value OK?



YES



The measurement value is OK.End of test



NO



The measurement value is not OK.Possible cause and remedy



- Lines between N3/10 (ME-SFI [ME] control unit) and M16/6m1 (Actuator motor)



- M16/6m1 (Actuator motor)



End of test



1.3. Test voltage supply of the potentiometers of component M16/6 (Throttle valve actuator).



Test prerequisite

- The power supply of component N3/10 (ME-SFI [ME] control unit) is OK.



Test sequence



- Switch off ignition.



- Connect socket box (126-pin) to component N3/10 (ME-SFI [ME] control unit).



- Measure direct voltage with multimeter between sockets (M.39) 39 and (M.43) 43 of the 35-pole socket box tester.



- Switch on ignition.



Specified value



- Voltage[4.75...5.25] V



Question



- Is the measurement value OK?
