Figure legend





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

Test sequence
- Switch off ignition
- Measurement with multimeter
- (X63/4) 2.2<-->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?

No
- The measured value is not o.k.
Possible cause and remedy
- Cable from component N3/10 (ME-SFI control module) 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 control module).
**End of test**

Yes
- The measured value is o.k.
