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
Shifting from 1st to O/D is performed in combination with "ON" and "OFF" operation of the shift solenoid valves SL1 and SL2 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 (Fail safe function).
