DTC P0976 Shift Solenoid "B" Control Circuit Low (Shift Solenoid Valve S2); DTC P0977 Shift Solenoid "B" Control Circuit High (Shift Solenoid Valve S2): Description
WARNING: This page is about a different car, the 2007 Toyota Land Cruiser. 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 the ON and OFF operation of the shift solenoid valves SL1, SL2, S1, S2 and SR, which is controlled by the ECM. If an open or short circuit occurs in the shift solenoid valves, the ECM controls the remaining normal shift solenoid valve to allow the vehicle to be operated safely (see FAIL-SAFE CHART ).
