DTC P190F-9F: Forced Hybrid/EV System Shutdown Performance Stuck Off [09/2023 - ]: Description
WARNING: This page is about a different car, the 2024 Lexus TX 500h. However, it is still accessible from the selected car via links, so may be relevant.
The hybrid vehicle control ECU assembly sends a block signal to the TCM to shutdown the power supply to the solenoid valve. When the system is not in the on (READY) state, it sends an SOLD (shutdown signal) signal from the hybrid vehicle control ECU assembly to the TCM to check the function of the HV gate block. When a malfunction is detected in the HV gate block function, DTCs are stored.
