WARNING: This page is about a different car, the 2025 Toyota Corolla Cross, 2024 Toyota Corolla Cross, and 2023 Toyota Corolla Cross. However, it is still accessible from the selected car via links, so may be relevant.

If the ignition switch is ON, the battery ECU assembly applies current to the MREL terminal to turn the IGCT relay on. This supplies power to the IGCT terminals.
