FAIL-SAFE CHART
Description
This function minimizes the loss of the Continuously Variable Transaxle (CVT) system functions when a malfunction occurs in a sensor or solenoid valve.
Fail-safe
(a) Fail-safe control list:
|
Malfunctioning Part |
Function |
|---|---|
|
Transmission revolution sensor (NT) |
The oil pressure of the primary pulley and secondary pulley is set to a specified value. The opening angle of the throttle valve is limited to reduce input torque. |
|
Transmission revolution sensor (NOUT) |
|
|
Transmission revolution sensor (NIN) |
|
|
Shift solenoid valve SL |
The ECM stops sending current to the shift solenoid valve SL, and forward and reverse clutch control is performed mechanically. Lock-up clutch control is canceled. |
|
Shift solenoid valve SC |
The ECM stops sending current to the shift solenoid valve SC, and forward and reverse clutch control is performed mechanically. Lock-up clutch control is canceled. |
|
Shift solenoid valve SLU |
The ECM stops sending current to the shift solenoid valve SLU, and forward and reverse clutch control is performed mechanically. Lock-up clutch control is canceled. |
|
Shift solenoid valve SLP |
The gear ratio is limited to a specified range. |
|
Shift solenoid valve SLS |
|
|
CVT fluid temperature sensor |
The ECM sets the fluid temperature to a predetermined value to perform normal control. |
