Code P0982 Scion Description

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 Engine Control Module (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).
