2010 Mercedes Benz C 300 (204.054) V6-3.0L (272.947) Page 306


- Measure direct current with multimeter between sockets [F.4] 100 and [M.1] 1 of the 126-pole socket box tester.



- Switch on ignition.



Testing of maximum power consumption may be conducted for no longer than 5 s.Specified value



- Amperage[1.0...1.8] 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



- N10/1f43 (Fuse 43)



- Line from component Y49/5 (Right camshaft intake solenoid) to component N3/10 (ME-SFI [ME] control unit)



- Y49/5 (Right camshaft intake solenoid)



End of test



0281



Component Y49/4 (Left camshaft intake solenoid) has a short circuit to positive. (P2093)



Possible cause:



- Y49/4 (Left camshaft intake solenoid)



Affected functions:



- Engine diagnosis



- Engine output



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



Test 1: Check component Y49/4 (Left camshaft intake solenoid).



1. Check component Y49/4 (Left camshaft intake solenoid).



Test 1.1: Test actuation of component Y49/4 (Left camshaft intake solenoid).



Test 1.2: Test current consumption of component Y49/4 (Left camshaft intake solenoid).



1.1. Test actuation of component Y49/4 (Left camshaft intake solenoid).



Test prerequisite



- Engine at idle



- Vehicle stationary



- Coolant temperature > 80锟斤拷 C



- Time since engine start> 60 s



Status of relevant actual value:



- Temperature of coolant:Warning! Communication with ECU required.



Note



- After the actuation it may be necessary to erase the fault memory!



Proceed to 'Actuation' with F2



1.2. Test current consumption of component Y49/4 (Left camshaft intake solenoid).
