Test 1.1.3.2.2.2: Test total resistance of engine compartment CAN.



Test 1.1.3.2.2.3: Test terminating resistor of component X30/5 (Left voltage distributor (CAN) connector).



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



Test terminating resistor of component N3/10 (ME-SFI [ME] control unit).



Test sequence



- Switch off ignition.



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



- Connector F is plugged in at control unit.



- Unplug the socket F from the wiring harness at the socket box.



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



Specified value



- Resistor[115...125]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



- Control unit N3/10 (ME-SFI [ME] control unit)



End of test
