CONSTRUCTION AND OPERATION
(a) Engine Switch
The engine switch consists of a momentary type
switch, 3 color (amber, green, greenish white)
LEDs, and a transponder key amplifier.
• The greenish white LED is for illumination.
• The amber and green LEDs are for the indicator
lights. The driver can check the present power
source mode and whether the engine can start in
accordance with the illumination state of the
indicator light.
• When the main body ECU detects an
abnormality in the push-button start function, it
makes the amber indicator light flash. If the
engine stopped in this state, it may not be
possible to restart it.
(b) Indicator Light Condition

(c) Main body ECU
The main body ECU consists of the IG1 and IG2
relay actuation circuits and CPU.
HINT:
Before removing the battery, make sure to turn the
engine switch off. The main body ECU constantly
stores the present power source mode in its
memory. Therefore, if the main body ECU is
interrupted by disconnecting the battery, the main
body ECU restores the power source mode after the
battery is reconnected. For this reason, if the battery
is disconnected when the engine switch is not off,
the power will be restored to the vehicle at the same
time the power is restored to the main body ECU (by
reconnecting the battery).
