Circuit description

Signals from the transmission control computer ASSY change the vehicle speed from 1st to 6th gear according to the combination of the transmission 3 way solenoid ASSY (S1, S2, S3, S4, SR) and the clutch control solenoid No.1 (SL1, SL2). When there is an open or short circuit in the solenoid valve system, the transmission control computer ASSY stops continuity to all solenoids as the fail safe function. As a result, only the mechanical hydraulic circuit is available and the manual shift control is initiated.





Monitor description

This diagnostic code indicates open or short circuit in the shift solenoid valve SL2 circuit. TCM switches ON/OFF of the shift solenoid valve to command shifting. If there is open or short circuit in any of the shift solenoid valve circuits, TCM detects the defect, turns on MIL, and records the diagnostic code.
