DTC P099B, P099C; Shift Solenoid "G" Control Circuit Low (Shift Solenoid Valve SC) [08/2014 - ]: Description

WARNING: This page is about a different variant/trim than selected.

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.
