Consequently, the customer's vehicle may already return to the normal condition. Refer to
FAIL-SAFE FUNCTION
1st fail-safe
The mode that the vehicle can stop safely, to prompt the driver to stop if the malfunction occurs and to shift to
2nd Fail-Safe early. It shifts to 2nd Fail-Safe or Final Fail-Safe after the vehicle stopped.
2nd fail-safe
The mode that the vehicle shifts to Final Fail-Safe without changing the behavior, by identifying the malfunc-
tioning parts in the condition that the driving force required for the driving is secured.
Final fail-safe
• Selects the shifting pattern that the malfunctioning parts identified at 1st and 2nd Fail-Safe are not used, and
then secure the driving force that is required for the driving.
• The mode that the shifting performance does not decrease by normal shift control.

Protection Control
INFOID:0000000005250137
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 has the following protection control.
REVERSE INHIBIT CONTROL
Intercepts the torque transmission and shift 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.
1ST ENGINE BRAKE PROTECTION CONTROL
Controls the engine brake so as not to make effective by turning the front brake solenoid output to OFF when
each solenoid becomes the electricity pattern of 1st engine brake during driving at the vehicle speed 25 km/h
or more in any positions other than “R” position or 1GR.
TCM HIGH TEMPERATURE PROTECTION CONTROL
Limit the accelerator opening and forcibly control the vehicle to the low torque driving when the electronic sub-
strate in TCM reaches the high temperature.
