WARNING: This page is about a different car, the 2024 Lexus LS 500h. However, it is still accessible from the selected car via links, so may be relevant.
The EV mode signal will be sent to the hybrid vehicle control ECU assembly when the EV mode switch (integration control & panel assembly) is operated. If the specified conditions are met, the system enters EV mode and the vehicle will be driven using EV mode. This signal is then transmitted from the hybrid vehicle control ECU assembly via CAN to the combination meter assembly to illuminate the EV mode indicator.
