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)
