Monitor Description
With the shift lever in P, N, D or M, the shift solenoid valve SLG controls the S1 synchronizer and moves it to the requested position according to the requested shift mode.
When the TCM detects that the S1 synchronizer is not in the appropriate position, it determines that the shift solenoid valve SLG or shift stroke sensor is malfunctioning, illuminates the MIL and stores a DTC.
