Warning!
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 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
Amperage[1.0...1.8] A
Question
Is the measurement value OK?
YES
The measurement value is OK.End of test
