HYBRID CONTROL SYSTEM Pattern Select Switch Sport Mode Circuit

DESCRIPTION

When selecting SPORT*1 or SPORT S/S+*2 mode, the switch operation signal is sent to the ECM. Following this, the drive torque is optimally controlled to obtain a sporty feel in response to the driver's accelerator pedal operation.
