2010 Mercedes Benz C 300 (204.054) V6-3.0L (272.947) Page 696

Test prerequisite

- The actual value is not o.k.

- 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 [F.11] 107 and [F.23] 119 of the 126-pole socket box tester.

- Switch on ignition.

Specified value

- Voltage[4.75...5.25] V

Question

- Are the measurement values OK?

YES

The measurement values are OK.Further possible causes of fault

- Signal lines

- B37 (Accelerator pedal sensor)

End of test

NO

The measurement values are not OK.Possible cause and remedy

- Cable for voltage supply

End of test
