2010 Mercedes Benz C 300 (204.054) V6-3.0L (272.947) Page 534


- G3/6 (Right O2 sensor, after TWC [KAT])



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



- N10/1f57 (Fuse 57)



- Voltage supply via component Z7/36 (Circuit 87 M2e connector sleeve)



Affected functions:



- Engine diagnosis



- Exhaust system



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



Test 1: Check power supply of component N3/10 (ME-SFI [ME] control unit).



Test 2: Arrangement of fuses



Test 3: Power supply



Test 4: Check component G3/6 (Right O2 sensor, after TWC [KAT]).



1. Check power supply of component N3/10 (ME-SFI [ME] control unit).



Test 1.1: Test voltage supply of circuit 87. ( Check using actual value )



Test 1.2: Test voltage supply of circuit 30.



Test 1.3: Test voltage supply of circuit 87.



Test 1.4: Test current consumption of component N10/1kR (Circuit 87 relay, engine).



Test 1.5: Test voltage supply of circuit 15.



1.1. Test voltage supply of circuit 87. ( Check using actual value )



Test prerequisite



- The voltage test at component G1 (Battery) is o.k.



- Ignition ON



Status of relevant actual value:



- Battery voltage:Warning! Communication with ECU required.



Specified value



- Battery voltage[11.0 ... 15.0] V



Question:Is the actual value o.k.?



YES



The actual value is okay.End of test



NO



The actual value is not o.k.Possible cause and remedy



- Test voltage supply of circuit 30.



- Test voltage supply of circuit 87.



1.2. Test voltage supply of circuit 30.



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