Protection Control
The TCM becomes the protection control status temporarily to protect the safety when the safety of TCM and transmission is lost. It automatically returns to the normal status if the safety is secured.
The TCM is equipped with the following protection control.
REVERSE INHIBIT CONTROL
Intercepts the torque transmission and shifts to the neutral status if the selector lever is shifted to "R" position while the vehicle moves forward at the vehicle speed 10 km/h (7 MPH) or more.
TCM HIGH TEMPERATURE PROTECTION CONTROL
When the ATF becomes hot, the shifting pattern is changed for preventing fluid temperature rise.
TORQUE-DOWN CONTROL WHEN CONTINUOUS STALL OCCURS IN D POSITION
If the accelerator pedal is continually depressed for a certain length of time when the selector lever is in the "D"
position and the vehicle is parked, the engine output is limited for protecting the transaxle.
O/D PROHIBIT CONTROL AT LOW TEMPERATURES
When the ATF temperature is low immediately after engine start, shifting to 4GR is prohibited for protecting the transaxle and allowing the exhaust gas characteristics to warm up quickly.
