WARNING: This page is about a different car, the 2006 Lexus RX 400h. However, it is still accessible from the selected car via links, so may be relevant.
If the difference between the requested MGR torque and the actual MGR torque exceeds a predetermined value, the MG HVECU determines that there is a malfunction in the execution or monitoring of the MGR torque. Then, the HV control ECU illuminates the MIL and sets a DTC.
