Test sequence
­ Switch off ignition.
­ Connect 126­pole socket box between engine wiring harness and control module N3/10 (ME­SFI [ME] control unit).
­ Measure direct voltage with multimeter between sockets (M.80) 80 and (M.44) 44 of the 126­pole socket box tester.
­ Switch on ignition.
Specified value
­ Voltage[4.8...5.3] V
Question
­
Is the measurement value OK?
YES
The measurement value is OK.Possible cause and remedy
­ Signal wire
­ Test cables to component B70 (Crankshaft Hall sensor) for open circuit.
­ B70 (Crankshaft Hall sensor)
End of test
NO
The measurement value is not OK.Possible cause and remedy
­ Check lines to component B70 (Crankshaft Hall sensor) for short circuit.
