Monitor Description

WARNING: This page is about a different car, the 2024 Lexus IS 500, 2023 Lexus IS 500, and 2022 Lexus IS 500. However, it is still accessible from the selected car via links, so may be relevant.

The TCM calculates the amount of heat absorbed by the friction material based on the difference in revolution speed (clutch slippage) between the turbine and output shaft. The TCM illuminates the MIL and stores this DTC when the amount of heat absorption exceeds the specified value.

When the shift solenoid valve SLT remains ON, oil pressure goes down and clutch engagement force decreases.

NOTE:

If driving continues under these conditions, the clutches will burn out and the vehicle will no longer be drivable.
