STARTING CIRCUIT OPERATING FLOW OPERATING FLOW Battery(+) terminal Fusible link [CN-351 (40A)] Master switch [CS-74 (1) 供 (2)] I/conn [CN-01 (16, 17)] Fuse box [CN-36] Start switch [CS-02 (1)] ECM power relay [CR-30 (30)] Power relay [CR-35 (30)] 1) 侍 The gear selector lever is neutral position. It is necessary condition before the starting. The gear selector has an output signal which is activated whenever the shift lever is in the neutral position. This signal can be used to control a relay and prevent engine from starting whenever the shift lever is not in the neutral position.
