DTC P0985: Shift Solenoid "E" Control Circuit Low (Shift Solenoid Valve SR); DTC P0986: Shift Solenoid "E" Control Circuit High (Shift Solenoid Valve SR) [11/2021 - ]: 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.
Based on the ON-OFF combinations of the SL1, 2, 3, 4 and 5, SLT, SLU, SL and SR solenoids, the TCM performs gear shifts from 1st gear to 8th gear. If a circuit related to a solenoid valve is open or shorted, the TCM uses the fail-safe function to turn other solenoid valves on or off. If all solenoid valves are malfunctioning, only the mechanical fluid pressure circuit will function and some manual operation will be possible. If an open or short has occurred, the TCM cuts power to the malfunctioning solenoid valve.
