Fail-safe control list:
Malfunctioning Part Function Transmission revolution sensor (NIN) The ECM calculates the input shaft speed based on a signal from the turbine speed sensor to perform normal control. Transmission revolution sensor (NOUT) The ECM calculates the output shaft speed based on a signal from the speed sensor to perform normal control. Transmission revolution sensor (NT) The ECM calculates the turbine speed based on a signal from the primary pulley speed sensor to perform normal control. Shift solenoid valve DS1 The ECM stops current to the solenoid valve. The gear ratio is adjusted to a lower ratio compared to the normal ratio. Shift solenoid valve DS2 The ECM stops current to the solenoid valve. The gear ratio is adjusted to the highest ratio. Shift solenoid valve SL The ECM stops current to the solenoid valve to cancel lock-up. Moreover, forward and reverse clutch pressure control using shift solenoid valve SLS is canceled and forward and reverse clutch pressure control is performed only by controlling the oil pressure. Shift solenoid valve DSU The ECM stops current to the solenoid valve to completely cancel lock-up. Shift solenoid valve SLS The ECM stops current to the solenoid valve to maximize the secondary oil pressure in order to set the gear ratio to a predetermined value. Moreover, forward and reverse clutch pressure control using shift solenoid valve SLS is canceled and forward and reverse clutch pressure control is performed only by controlling the oil pressure. CVT fluid temperature sensor The ECM sets the fluid temperature to a predetermined value to perform normal control.
