Pattern Select Switch EV Mode Circuit [08/2023 - ]: Description

WARNING: This page is about a different car, the 2025 Lexus RX 450h+ and 2024 Lexus RX 450h+. 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 when the AUTO EV/HV mode switch 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 via CAN to the combination meter assembly to illuminate the AUTO EV/HV mode indicator.
