DTC P0976: Shift Solenoid "B" Control Circuit Low (Shift Solenoid Valve S2); DTC P0977: Shift Solenoid "B" Control Circuit High (Shift Solenoid Valve S2) [09/2014 - 11/2017]: Description
WARNING: This page is about a different car, the 2017 Lexus RC 350, 2017 Lexus RC 300, 2016 Lexus RC 350, 2016 Lexus RC 300, and 2015 Lexus RC 350. However, it is still accessible from the selected car via links, so may be relevant.
Shifting from 1st to 6th is performed in combination with "ON" and "OFF" operation of the shift solenoid valves SL1, SL2, S1, S2, S3, S4 and SR which is 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 valve to allow the vehicle to be operated smoothly. (In case of an open or short circuit, the ECM stops sending current to the circuit.) Fail-safe function.
Refer to FAIL-SAFE CHART [09/2014 - 10/2015] , or refer to FAIL-SAFE CHART [10/2015 - 11/2017]
