DTC P0A79-701 Drive Motor "B" Inverter Performance: 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.
Refer to the description of the inverter. (See DTC P0A78-266 DRIVE MOTOR "A" INVERTER PERFORMANCE: DTC P0A78-267 DRIVE MOTOR "A" Inverter Performance )
If the inverter receives a rear motor gate shutdown signal from the MG ECU, it will turn all power transistors off which are activating the Rear Motor to forcibly stop Rear Motor operation.
The MG ECU monitors rear motor gate shutdown signals and detects a malfunction.
