Terminals Of Ecu [11/2023 - ]
WARNING: This page is about a different car, the 2025 Toyota Highlander and 2024 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
*1 Inverter with Converter Assembly HINT:
Since the inverter with converter assembly uses waterproof connectors, the voltage and waveforms cannot be inspected directly. Standard voltage readings and waveforms are indicated for reference only.
