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 difference between the requested generator (MG1) torque and the actual generator (MG1) torque exceeds a predetermined value, the MG ECU determines that there is a malfunction in the execution or monitoring of the generator (MG1) torque. 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.
