FAIL-SAFE CHART
1. Fail-safe
This function minimizes the loss of operation when any abnormality occurs in a sensor or solenoid.
Fail-safe Control List
Malfunction Part |
Function |
---|---|
Transmission revolution sensor (NT) |
During a transmission revolution sensor (NT) malfunction, shift control is performed based on the transmission revolution sensor (SP2) signal. |
Transmission revolution sensor (SP2) |
During a transmission revolution sensor (SP2) malfunction, shift control is performed based on the wheel speed sensor signal. |
ATF temperature sensors (No. 1 and No. 2) |
During an ATF temperature sensor malfunction, up-shifting to 5th and 6th is prohibited. |
Shift solenoid valve SL1, SL2, SL3 and SL4 |
Stop the conduction of electric power to a failed solenoid and shift gears by turning on/off normal solenoids. If all solenoids are malfunctioning, gears will be selected through mechanical hydraulic circuits. |
Shift solenoid valve SLT |
During a shift solenoid valve SLT malfunction, the current to the shift solenoid valve is stopped. However, shifting is performed through normal clutch pressure control. |
Shift solenoid valve SLU |
During a shift solenoid valve SLU malfunction, the current to the shift solenoid valve is stopped. This stops lock-up control, thus decreasing fuel economy. |
