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.95] 95 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
