DTC P0787: Shift / Timing Solenoid Low (Shift Solenoid Valve ST); DTC P0788: Shift / Timing Solenoid High (Shift Solenoid Valve ST): Description
WARNING: This page is about a different car, the 2011 Toyota Matrix. However, it is still accessible from the selected car via links, so may be relevant.
Shift solenoid valve ST is switched ON-OFF by a signal from ECM so that let in or out timing of 2nd brake is adjusted by operating orifice control valve. Therefore, shift solenoid valve ST operates when letting in or out reverse clutch.
If the shift solenoid valve ST is broken, the shift shock becomes big.
