Test prerequisite

- Fault code '201D' present
Status of relevant fault code:Test sequence

- Switch off ignition.
- Connect socket box (126-pin) to component N3/10 (ME-SFI [ME] control unit).
- Measure resistance with multimeter between sockets (2.12) 21 and (3.4) 37 of the 126-pole socket box tester.
Specified value

- Resistor[11...17]ohms
Question

- Is the measurement value OK?


YES
The measurement value is OK.Note

- In the event of stored faults with a high fault frequency count or in the event of customer complaints, check lines and connectors for loose contact and corrosion..


NO
The measurement value is not OK.Test sequence

- Switch off ignition.
- Connect shop-made test cable set to component Y62y1 (Fuel injector cylinder 1).
- Measure resistance with multimeter between pins (Y62) 1 and (Y62) 2
Specified value

- Resistor[14...20]ohms
Question

- Is the measurement value OK?


YES
The measurement value is OK.Possible cause and remedy

- Lines to component Y62y1 (Fuel injector cylinder 1)


NO
The measurement value is not OK.Possible cause and remedy

- Y62y1 (Fuel injector cylinder 1)


1.1.3. Test leaktightness and ejection pattern of component Y62y1 (Fuel injector cylinder 1).
