ECU Data (for PRIUS, RX400h, GS450h and CAMRY HV)
• The HV ECU and the battery ECU have a lot of ECU data.
• The following describes the contents and uses of ECU data based on systems.
• Data from which driving conditions can be learned are shown using a ↔, and data which can be utilized for troubleshooting are shown using a ∂. (Other data items also need to be confirmed, because they might be important depending on the situation.)
