Fail-Safe Function
If any malfunction occurs in a sensor or solenoid, this function controls the A/T to make driving possible.
NOTE:
Line pressure is set at the maximum in fail-safe mode. Although gear position differs depending on the type of fail-safe modes, CONSULT-II indicates "5th".
FAIL-SAFE FUNCTION CHART
| DTC | Malfunction items | Fail-safe* |
|---|---|---|
| P0500 | Vehicle speed signal | No learning control. |
| P0613 | TCM processor | Fail-safe mode 4 |
| P0705 | PNP switch | Fail-safe mode 4 |
| P0710 | ATF temperature sensor circuit | Sets ATF temperature data at 111°C (232°F) after 15 minutes. Inhibits lock-up control. |
| P0711 | ATF temperature sensor function | Sets ATF temperature data at 111°C (232°F) after 15 minutes. Inhibits lock-up control. |
| P0717 | Turbine revolution sensor | Fail-safe mode 1 |
| P0722 | Revolution sensor | Uses vehicle speed signal from combination meter as a substitute. Inhibits learning control. |
| P0726 | Engine speed signal Input circuit performance | Fail-safe mode 1 |
| P0731 | 1st gear function | No 1st gear, no control for N-D shift. |
| P0732 | 2nd gear function | Fail-safe mode 1. Also, ECM restricts engine torque to prevent clutch slipping. |
| P0733 | 3rd gear function | Fail-safe mode 1. Also, ECM restricts engine torque to prevent clutch slipping. |
| P0734 | 4th gear function | Fail-safe mode 1. Also, ECM restricts engine torque to prevent clutch slipping. |
| P0735 | 5th gear function | Fail-safe mode 1. Also, ECM restricts engine torque to prevent clutch slipping. |
| P0744 | Lock-up function | Fail-safe mode 1 |
| P0745 | Pressure control solenoid valve A | Fail-safe mode 1. Also, ECM restricts engine torque to prevent clutch slipping. |
