DTC P099B: Shift Solenoid "G" Control Circuit Low (Shift Solenoid Valve SC); DTC P099C: Shift Solenoid "G" Control Circuit High (Shift Solenoid Valve SC) [01/2019 - 11/2022]: Description
WARNING: This page is about a different car, the 2022 Toyota Corolla, 2021 Toyota Corolla, 2020 Toyota Corolla, and 2019 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
Based on the signal received by the shift solenoid valve SC, the ECM uses the shift solenoid valve SLU to control the forward and reverse clutch pressure.
If there is an open or short in the shift solenoid valve SC circuit, the ECM stops sending current to the malfunctioning shift solenoid valve.
