CVT CONTROL SYSTEM : Fail-safe

INFOID:0000000010622453

TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of
the main electronically controlled input/output parts is damaged.
If the vehicle shows following behaviors including “poor acceleration”, a malfunction of the applicable system
is detected by TCM and the vehicle may be in a fail-safe mode. At this time, check the DTC code and perform
inspection and repair according to the malfunction diagnosis procedures.

CVT CONTROL SYSTEM : Protection Control

INFOID:0000000010622454

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.

CONTROL FOR WHEEL SPIN

TORQUE IS REDUCED WHEN DRIVING WITH THE REVERSE GEAR

CONTROL WHEN FLUID TEMPERATURE IS HIGH

DTC

Vehicle behavior

Conditions of vehicle

Control

When a wheel spin is detected, the engine output and gear ratio are limited and the line pressure is increased.
Limits engine output when a wheel spin occurs in any of right and left drive wheels.

Vehicle behavior in
control

If the accelerator is kept depressing during wheel spin, the engine revolution and vehicle speed are limited to
a certain degree.

Normal return condi-
tion

Wheel spin convergence returns the control to the normal control.

Control

Engine output is controlled according to a vehicle speed while reversing the vehicle.

Vehicle behavior in
control

Power performance may be lowered while reversing the vehicle.

Normal return condi-
tion

Torque returns to normal by positioning the selector lever in a range other than “R” position.
