CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P099B and P099C

DTC Code DTC Name
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.

DTC No.
