Title: HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM (for NICKEL METAL HYDRIDE BATTERY): Pattern Select Switch Sport Mode Circuit; 2018 - 2024 MY Camry HV [07/2017 -        ]

Pattern Select Switch Sport Mode Circuit

DESCRIPTION

When selecting SPORT mode, the switch operation signal is sent to the hybrid vehicle control ECU assembly. 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 assembly via CAN to the combination meter assembly to illuminate the SPORT mode indicator.
