NOTES Notes on avoiding damage to ignition system Engines 104, 111, 112, 113, 119, 120 with ME-SFI fuel injection and ignition system AH15.10-P-0002-01D
  ME-SFI fuel injection and ignition system diagnosis previous knowledge   AD07.61-P-2000D
  Connection and use of testing equipment   AD00.00-P-1000AZ
  Connect hand-held-tester (HHT) and read out fault memory   AD00.00-P-2000-03A
IMPORTANT Remove center connector first when removing connectors from ME-SFI control module, and plug in center connector D last when reconnecting.    
IMPORTANT Measuring equipment/test connection column: The numbers in brackets such as => 1.0 (2A) mean:
A = Connector A in wiring diagram
2 = Socket 2 in wiring diagram
   
a Ignition: OFF     
b Connect test wiring harness with socket box to ME-SFI control module (N3/10) in accordance with connection plan IMPORTANT Connector with red marking is not required at present, since no function available in ME-SFI control module yet AD07.61-P-2000-01A
