Starting Operation

Engine starting

Jika start switch diputar ke START position, arus listrik mengalir sbb :

• Start switch terminal (B+)
• Terminal C → Start power relay (RE3302) coil → Ground
• V-ECU (VA58) → Start relay (RE3301) → Ground

Ketika start power relay dan start relay bekerja :

• Fuse (FU22, 15A) → Start power relay (RE3302) → Start relay (RE3301) → Start motor relay coil → E-ECU (B29) → E-ECU ground

Starter motor MO3301 disupply langsung dari battery disconnection switch dan memiliki start relay bawaan yang tegangannya dikontroleh oleh control unit E-ECU. Relay RE3301 dikontrol oleh V-ECU ketika start switch SW3301 diputar ke posisi 2.
