- W16/Measure resistance with multimeter between 3 and (2.47) 81 of the 35-pole socket box tester.
Specified value
- Resistor< 1ohms
Question
- Are the measurement values OK?
YES
The measurement values are OK.Note
- In the event of stored faults with a high fault frequency count or in the event of customer complaints, check lines and connectors for loose
contact and corrosion..
End of test
NO
At least one of the measured values is not o.k.Possible cause and remedy
- Ground cable
- W16/3 (Ground (left of component compartment, power ground))
End of test

Question
- Is the measurement value OK?
YES
The measurement value is OK.Possible cause and remedy
- Replace component N15/3 (ETC [EGS] control unit).
End of test
NO
The measurement value is not OK.Possible cause and remedy
- Inspect connector 2 at control unit N15/3 (ETC [EGS] control unit) for damage, correct connection, loose contact and corrosion and repair, if
necessary.
