Monitor Description

WARNING: This page is about a different car, the 2024 Lexus TX 550h+. However, it is still accessible from the selected car via links, so may be relevant.

When the value obtained by subtracting the temperature detected by the No. 2 ambient temp. sensor (thermistor assembly) from the temperature detected from the ambient temp. sensor (thermistor assembly) is the threshold or more, the air conditioning amplifier assembly illuminates the MIL and stores the DTC.
