Test 1: Check component L5 (Crankshaft position sensor).

1. Check component L5 (Crankshaft position sensor).

Test 1.1: Test signal voltage of component L5 (Crankshaft position sensor).

Test 1.2: Check internal resistance of component L5 (Crankshaft position sensor).

1.1. Test signal voltage of component L5 (Crankshaft position sensor).
Test sequence

- Switch off ignition.
- Connect socket box (126-pin) to component N3/10 (ME-SFI [ME] control unit).
- Observe oscilloscope pattern between sockets (3.13) 46(A4) and (3.26) 59(A7) of the 126-pole socket box tester.
- Engine at idle
- Start measuring system.
Specified value

- Compare the oscillogram with the characteristics specified for component L5 (Crankshaft position sensor).[1 ... 40] V Sinusoidal signal(Amplitude)
Note

- Measuring system:Communication with ECU required


1.2. Check internal resistance of component L5 (Crankshaft position sensor).
Test sequence

- Switch off ignition.
- Connect socket box (126-pin) to component N3/10 (ME-SFI [ME] control unit).
- Separate connector 3 from control unit N3/10 (ME-SFI [ME] control unit).
- Measure resistance with multimeter between sockets (3.13) 46 and (3.26) 59 of the 126-pole socket box tester.
