Monitor Description

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.

The ECM monitors the speed of the inverter water pump with motor assembly. When the speed becomes a certain value or more, the ECM judges that the speed is abnormally high and stores a DTC (The MIL does not illuminate).
