Pattern Select Switch Sport Mode Circuit

HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: Pattern Select Switch Sport Mode Circuit
- Pattern Select Switch Sport Mode Circuit

DESCRIPTION

When selecting sport 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 acceleration operation.
