1. Negative battery cable is connected
|
Operation condition
• Capacitor (i-ELOOP) voltage is less than 7.5 V
Power supply method
• The capacitor (i-ELOOP) relay is turned off and the pre-charge relay is turned on, and power is supplied from the battery to the capacitor (i-ELOOP) (to capacitor (i-ELOOP) voltage of 9.5 V or more) via the pre-charge relay.

2. Ignition switched ON (engine off to on)
|
Operation condition
• Capacitor (i-ELOOP) voltage is less than 7.5 V
Power supply method
1. The capacitor (i-ELOOP) relay is turned off, the bypass relay is turned on, and the pre-charge relay is turned on, and power is supplied from the generator to the capacitor (i-ELOOP) via the pre-charge relay through the bypass relay. At this time, it remains fixed in bypass mode until the ignition is switched OFF.
2. The pre-charge ends at the point where the capacitor (i-ELOOP) voltage is 9.5 V or more.

• If the ignition is switched OFF during pre-charge mode and the capacitor (i-ELOOP) charge is insufficient, the pre-charge mode continues.
Operation condition
• Hood is closed and capacitor (i-ELOOP) voltage is less than 9.5 V
Power supply method
• The capacitor (i-ELOOP) relay is turned off and the pre-charge relay is turned on, and power is supplied from the battery to the capacitor (i-ELOOP) (to capacitor (i-ELOOP) voltage of 9.5 V or more) via the pre-charge relay.
