2010 Mercedes Benz C 300 (204.054) V6-3.0L (272.947) Page 263


- Measure direct current with multimeter between sockets [F.4] 100 and [M.54] 54 of the 126-pole socket box tester.



- Switch on ignition.



Specified value



- Amperage[0.6...1.2] A



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



- N10/1f57 (Fuse 57)



- N10/1kR (Circuit 87 relay, engine)



- Check lines from component N3/10 (ME-SFI [ME] control unit) to component Y110 (Three-disk thermostat valve).



- Y110 (Three-disk thermostat valve)



End of test



0160



M16/6 (Throttle valve actuator) : Actual value potentiometer 1 or 2 has failed. (P2135)



Possible cause:



- M16/6 (Throttle valve actuator)



Affected functions:



- Engine diagnosis



- Engine output



-------------------------------------------------



Test 1: Check component M16/6 (Throttle valve actuator).



1. Check component M16/6 (Throttle valve actuator).



Test 1.1: Check component M16/6 (Throttle valve actuator) using actual value.



Test 1.2: Test voltage supply of the potentiometers of component M16/6 (Throttle valve actuator).



1.1. Check component M16/6 (Throttle valve actuator) using actual value.



Warning!Communication with ECU required.



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



Test prerequisite



- At least one of the relevant actual values is not okay.



- 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?
