Monitor Description

WARNING: This page is about a different car, the 2025 Lexus RX 450h+ and 2024 Lexus RX 450h+. However, it is still accessible from the selected car via links, so may be relevant.

The charge control ECU built into the electric vehicle charger assembly monitors the DC portion current via the IVH sensor. When an IVH sensor malfunction on the system 2 side is detected, it illuminates the MIL and stores a DTC.
