Monitor Description
WARNING: This page is about a different car, the 2025 Lexus NX 350, 2024 Lexus NX 350, 2023 Lexus NX 350, and 2022 Lexus NX 350. However, it is still accessible from the selected car via links, so may be relevant.
The ECM calculates the amount of heat absorbed by the clutch discs and brake discs based on the difference in speed (clutch slippage) between the turbine (input) and output shaft. If the amount of heat absorption exceeds the specified value, the ECM will illuminate the MIL and store this DTC.
If the solenoid (SLT) valve is stuck ON, the line pressure and clutch engagement force will decrease.
NOTE:
If driving continues under these conditions, the clutches will burn out and the vehicle will no longer be drivable.
