*1: except Manual Transaxle
-
*2: In order to prevent the vehicle battery from being depleted when the vehicle is shipped long distances, a fuse that cuts unnecessary electrical load while the vehicle is being shipped is installed in the circuit. If the fuse is removed, the circuit becomes open. If the fuse that is between the vehicle battery and terminal CUTB is removed and the circuit is open, the certification ECU (smart key ECU assembly) changes to a certain control mode (example: the transmission of radio waves every 0.25 seconds, which form the detection area, stops).

Receives clutch start switch signal
-
Monitors whether the clutch start switch is on (clutch pedal depressed) or off(clutch pedal released). Applies voltage via a resistor (large) in the certification ECU (smart key ECU assembly). When the clutch start switch is on, due to the starter relay coil resistance (small) using some of the voltage, the voltage at terminal STAR will be low (2.7 V or less), and when the clutch start switch is off, the voltage will be high (9 V or more).

Receives neutral start switch (P, N position detection) signal
-
Monitors whether the neutral start switch is on (P or N) or off (other than P or N). Applies voltage via a resistor (large) in the certification ECU (smart key ECU assembly). When the neutral start switch is on, due to the starter relay coil resistance (small) using some of the voltage, the voltage at terminal STAR will be low (2.7 V or less), and when the neutral start switch is off, the voltage will be high (9 V or more).
