Monitor Description
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.
The MG ECU monitors the rear motor gate shutdown (RSDN) signal line. If the MG ECU detects an open or short malfunction of the RSDN signal circuit, the HV control ECU illuminates the MIL and sets a DTC.
