Test sequence
Switch off ignition.
Connect socket box (126­pin) to component N3/10 (ME­SFI [ME] control unit).
Measure direct current with multimeter between sockets [F.4] 100 and [M.48] 48 of the 126­pole socket box tester.
Switch on ignition.
Testing of maximum power consumption may be conducted for no longer than 5 s.Specified value
