Test 1: Check power supply of component N3/10 (ME-SFI [ME] control unit).

1. Check power supply of component N3/10 (ME-SFI [ME] control unit).

Test 1.1: Test voltage supply of circuit 87. ( Check using actual value )

Test 1.2: Test voltage supply of circuit 30.

Test 1.3: Test voltage supply of circuit 87.

1.1. Test voltage supply of circuit 87. ( Check using actual value )
Test prerequisite

- The voltage test at component G1 (Battery) is o.k.
- Ignition ON
Status of relevant actual value:
- Battery voltage:Warning! Communication with ECU required.
Specified value

- Battery voltage[11.0 ... 14.5] V
Question:Is the actual value o.k.?

YES
The actual value is okay.End of test

NO
The actual value is not o.k.Possible cause and remedy

- Test voltage supply of circuit 30.
- Test voltage supply of circuit 87.


1.2. Test voltage supply of circuit 30.
Test sequence

- Switch off ignition.
- Connect socket box (35-pin) to component N3/10 (ME-SFI [ME] control unit).
- Measure direct voltage with multimeter between sockets (5.5) 5 and (5.3) 3 of the 35-pole socket box tester.
- Measure direct voltage with multimeter between sockets (5.6) 6 and (5.3) 3 of the 35-pole socket box tester.
- Measure direct voltage with multimeter between sockets (5.7) 7 and (5.3) 3 of the 35-pole socket box tester.
- Switch on ignition.
Specified value

- Voltage[11.0...14.5] V
Question

- Are the measurement values OK?


YES
The measurement values are OK.Further possible causes of fault

- Test voltage supply of circuit 87.


NO
The measurement values are not OK.Possible cause and remedy

- F34f21 (Fuse 21)
- F34 (Interior fuse box)
- Lines

- Switch on ignition.
Specified value

- Voltage[11.0...14.5] V
Question

- Is the measurement value OK?


YES
The measurement value is OK.End of test

NO
The measurement value is not OK.Possible cause and remedy

- N10/1f43 (Fuse 43)
- N10/1kI (Circuit 87 relay, engine)
- Lines
End of test
