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 detects over-voltage, it transmits an over-voltage 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 signal, the hybrid vehicle control ECU assembly illuminates the MIL and store a DTC.
