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 excessive current flows through the motor inverter due to an internal short, the motor inverter transmits an inverter fail signal to the MG ECU. Upon receiving this signal, the hybrid vehicle control ECU assembly illuminates the MIL and stores a DTC.
