Note
- 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..
End of test
NO
The measured value is not within the specified value range.Possible cause and remedy
- Cables between component N10/1 (Driver-side SAM control unit with fuse and relay module) and control module A89 (DTR controller unit)
- Plug connection X11/36
1.1.3.2.1.3. Check power supply at control unit N3/10 (ME-SFI [ME] control unit).
Test 1.1.3.2.1.3.1: Test voltage supply of circuit 87. ( Check using actual value )
Test 1.1.3.2.1.3.2: Test voltage supply of circuit 30.
Test 1.1.3.2.1.3.3: Test current consumption of component N10/1kR (Circuit 87 relay, engine).
Test 1.1.3.2.1.3.4: Test voltage supply of circuit 15.
1.1.3.2.1.3.1. 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 ... 15.0] 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.
1.1.3.2.1.3.2. Test voltage supply of circuit 30.
