Monitor Description

WARNING: This page is about a different car, the 2019 Toyota Highlander, 2018 Toyota Highlander, and 2017 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.

If the boost converter (inverter with converter assembly) detects overvoltage, it will transmit an overvoltage signal to the MG ECU. Then the MG ECU will send information about the malfunction to the hybrid vehicle control ECU assembly. Upon receiving this information, the hybrid vehicle control ECU assembly will illuminate the MIL and store a DTC.
