- 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 [M.53] 53 of the 126-pole socket box tester.
- Switch on ignition.
Specified value
- Amperage[0.3...0.6] A
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
- N10/1f57 (Fuse 57)
- N10/1kI (Circuit 87 relay, engine)
- Line between component N3/10 (ME-SFI [ME] control unit) and component Y32 (Air pump switchover valve)
- Line between component N10/1 (Driver-side SAM control unit with fuse and relay module) and component Y32 (Air pump switchover valve)
- Y32 (Air pump switchover valve)
