- Line from component N3/10 (ME-SFI [ME] control unit) to component X30/5 (Left voltage distributor (CAN) connector)
- Test terminating resistor of component X30/5 (Left voltage distributor (CAN) connector).
- Test terminating resistor of CAN element in control module N3/10 (ME-SFI [ME] control unit).
End of test
1.1.3.2.2.1.2. 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.
Specified value
- Resistor[55...65]ohms
Question
- Is the measurement value OK?
YES
The measurement value is OK.End of test
NO
The measurement value is not OK.Possible cause and remedy
