- Inspect connector A at control unit N80 (Steering column module) for damage, correct connection, loose contact and corrosion and repair, if



necessary.



- Otherwise select further tests.



End of test



NO



The measurement value is not OK.Possible cause and remedy



- Line between component N80 (Steering column module) and component N10/1 (Driver-side SAM control unit with fuse and relay module)



- Z7/58 (Circuit 30 connector sleeve)



- Line between component N80 (Steering column module) and component W15/1 (Ground (right footwell))



- Z6 (Ground connector sleeve)



- N10/1 (Driver-side SAM control unit with fuse and relay module)



End of test



1.1.3.2.2. Resistance test of engine compartment CAN



Test 1.1.3.2.2.1: Test total resistance of engine compartment CAN.



Test 1.1.3.2.2.2: Test terminating resistor of component X30/5 (Left voltage distributor (CAN) connector).



Test 1.1.3.2.2.3: Test terminating resistor of CAN element in control module N3/10 (ME-SFI [ME] control unit).



1.1.3.2.2.1. Test total resistance of engine compartment CAN.



Test 1.1.3.2.2.1.1: Perform measurement at component X30/5 (Left voltage distributor (CAN) connector).



Test 1.1.3.2.2.1.2: Perform measurement at component N3/10 (ME-SFI [ME] control unit).



1.1.3.2.2.1.1. Perform measurement at component X30/5 (Left voltage distributor (CAN) connector).



Test total resistance of engine compartment CAN.



Figure legend



- X30/5 (Left voltage distributor (CAN) connector)



Test sequence



- Switch off ignition.



- Measurement with multimeter



- (X30/5) 2.Measure resistance with multimeter between pins 2 and 2.1 (X30/5)



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?
