- X63/4 (CAN databus adapter connector, 2-pin)

Test sequence

- Switch off ignition.

- Measurement with multimeter

- (X63/4) 2.Measure resistance with multimeter between pins 2 and 2.1 (X63/4)

Adapter cable no. W220 589 00 99 36 may be used.Specified value

- [55...65]ohms

Question:

- Is the measured value within the specified value range?

YES

The measurement value is OK.End of test

NO

The measurement value is not OK.Possible cause and remedy

- Line from component N3/10 (ME-SFI [ME] control unit) to component X63/4 (CAN databus adapter connector, 2-pin)

- Test terminating resistor of component X63/4 (CAN databus adapter connector, 2-pin).

- Test terminating resistor of CAN element in control module N3/10 (ME-SFI [ME] control unit).

End of test

1.3.2.2.1.2. Perform measurement at component N3/10 (ME-SFI [ME] control unit).

Test total resistance of the CAN engine.

Test sequence

- Switch off ignition.

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

- Measure resistance with multimeter between sockets (F.41) 11 and (F.54) 24 of the 35-pole socket box tester.
