K313 CVT  CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM  P099B  Shift Solenoid "G" Control Circuit Low (Shift Solenoid Valve SC)  P099C  Shift Solenoid "G" Control Circuit High (Shift Solenoid Valve SC)  


DESCRIPTION

Based on the signal received by the shift solenoid valve SC, the ECM uses the shift solenoid valve SLU to control the forward and reverse clutch pressure.

If there is an open or short in the shift solenoid valve SC circuit, the ECM stops sending current to the defective shift solenoid valve.

MONITOR DESCRIPTION

These DTCs indicate an open or short in the shift solenoid valve SC circuit. If there is an open or short in the shift solenoid valve SC circuit, the ECM detects the problem and stores a DTC.
