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 input AC current is monitored via the IAC sensor by the charge control ECU built into the electric vehicle charger assembly. When an overcurrent malfunction is detected on the system 2 side, it illuminates the MIL and stores a DTC.
