DTC P0982: Shift Solenoid "D" Control Circuit Low (Shift Solenoid Valve S4); DTC P0983: Shift Solenoid "D" Control Circuit High (Shift Solenoid Valve S4): 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.
Shifting from 1st to 5th is performed in combination with "ON" and "OFF" operation of the shift solenoid valves SL1, SL2, SL3, S4 and SR which are controlled by the ECM. If an open or short circuit occurs in either of the shift solenoid valves, the ECM controls the remaining normal shift solenoid valves to allow the vehicle to be operated smoothly (Fail safe function).
