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 [F.17] 113 of the 126pole socket box tester.
Switch on ignition.
Specified value
Amperage[8...15] mA
Question
Is the measurement value OK?

YES
The measurement value is OK.Other possible cause of fault
In the event of stored faults with a high fault frequency count or in the event of customer complaints, check lines and connectors
for loose contact and corrosion..
B4/15 (Fuel pressure sensor)
End of test
NO
The measurement value is not OK.Possible cause and remedy
Check lines to components N118/3 (Left fuel pump control unit) and N118/4 (Right fuel pump control unit) as per wiring diagram.
Further possible remedies
Read fault memories of the control units N118/3 (Left fuel pump control unit) and N118/4 (Right fuel pump control unit).
