Test sequence
- Switch off ignition.
- Connect socket box (126-pin) to component N3/10 (ME-SFI [ME] control unit).
- Measure direct current with multimeter between sockets [F.4] 100 and [F.17] 113 of the 126-pole socket box tester.
- Switch on ignition.
Specified value
- Amperage[0,1...0,3] A
- Component M3 (Fuel pump assembly) is switched on and is heard to run.
Question
- Is the measurement value OK?
YES
The test was okay.End of test
NO
The measurement value is not OK.Possible cause and remedy
- Lines to component N10/2kA (Fuel pump relay)
- N10/2kA (Fuel pump relay)
End of test
1.4. Compression test
Test prerequisite
- Connect battery charger.
- Ignition ON
- Engine not running
- Coolant temperature between 70锟斤拷 C and 90锟斤拷 C
Actual values:
- Coolant temperature:Warning! Communication with ECU required.
Note
- If the rpm difference is greater than 28 1/min, a cylinder leak test must be performed on all cylinders as per the repair instructions to pinpoint
the fault.
Proceed to 'Actuation' with F2
2. Check component B70 (Crankshaft Hall sensor).
Test 2.1: Test signal voltage of component B70 (Crankshaft Hall sensor).
