Connection A of test cable 108 may NOT be connected to connection B of the 126­pin socket box (050).
Test sequence
­ Switch off ignition.
­ Connect socket box (126­pin) to component N3/10 (ME­SFI [ME] control unit).
­ Measure direct voltage with multimeter between sockets [ F.2 ] 98 and [F.3] 99 of the 126­pole socket box tester.
­ Measure direct voltage with multimeter between sockets [ F.4 ] 100 and [ F.5 ] 101 of the 126­pole socket box tester.
­ Measure direct voltage with multimeter between sockets [ F.6 ] 102 and [ F.5 ] 101 of the 126­pole socket box tester.
­ Switch on ignition.
Specified value
­ Voltage[11.0...15.0] V
