DESCRIPTION When selecting
sport mode, the switch operation signal is sent to the hybrid vehicle
control ECU. Following this, the system enters sport mode and the
vehicle will be driven using sport mode. This signal is then transmitted
from the hybrid vehicle control ECU via CAN to the combination meter
assembly to illuminate the "SPORT" indicator. HINT: If
the power switch is turned off while in sport mode, the drive mode will
automatically be changed to normal mode when the power switch is turned
on (IG). WIRING DIAGRAM
