Fail-Safe

INFOID:0000000008285877

TCM has the electrical fail-safe mode. The mode is divided into a maximum of 3 phases (1st fail-safe, 2nd fail-
safe and final fail-safe) and functions so that the operation can be continued even if the signal circuit of the
main electronically controlled input/output parts is damaged.
Even if the electronic circuit is normal, the fail-safe mode may start under special conditions (such as when the
brake pedal is depressed suddenly from a hard wheel spin status to stop the rotation of wheels). In this case,
turn the ignition switch OFF and back to ON after 5 seconds to resume the normal shift pattern.

Consequently, the customer's vehicle may already return to the normal condition. Refer to 

TM-5, "Work Flow"

.

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 malfunction-
ing 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  fail-safe 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:0000000008285878

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 and 1GR.
