Fail-safe

INFOID:0000000009268103

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.

Protection Control

INFOID:0000000009268104

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

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.
At the 1GR, the clutch pressure is increased.

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. From the 1GR, upshift to a certain gear ratio is only allowed.

Normal return condi-
tion

Wheel spin convergence returns the control to the normal control.

Control

When the CVT fluid temperature is high, the gear shift permission maximum revolution and the maximum
torque are reduced than usual to prevent increase of the oil temperature.

Vehicle behavior in
control

Power performance may be lowered, compared to normal control.

Normal return condi-
tion

The control returns to the normal control when CVT fluid temperature is lowered.

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.
