Manufacturer recommends using Socket Box (129 589 00 21 00) for making measurements to prevent damage to electrical connectors and terminals. See Fig 1 . Manufacturer identifies all system components with an alphanumeric identification (i.e., N3/10 is for ME-SFI control module).

NOTE: When connecting test equipment, disconnect ME-SFI control module connector "D" first. When reconnecting connectors, connect connector "D" last. See ME-SFI CONTROL MODULE CONNECTOR IDENTIFICATION  .
