 WARNING!
Risk of severe injury when touching ignition parts which produce high voltages. Do not touch igntion components.
Persons with heart pacemakers are not to perform repairs on this type of ignition system.
1. Review WARNING! on pages 11/1 and 11/2,
2. Review  11 , 21 , 22 , 23 , 24 , 31 , 33 ,
3. Review section 0,
4. Connect HHTand readout DTC memory, see 11 ,
5. Ignition: OFF
6. Connect test cable with socket box as per "Connection Diagram - Socket Box", see 22 /5.
Connector with red marking is not required at this time since the engine control module has presently no function installed for it.
When disconnecting the connectors on the engine control module remove center connector (D) first, when reconnecting connectors install center connector (D) last.
Note regarding "Test Connection" column:
The numbers indicated in parentheses, for example,  1.0 (2A) signify:
2 = Socket 2 on wiring diagram.
A = Connector A on wiring diagram
