Fail-safe

INFOID:0000000009177522

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.

TCM

Protection Control 

INFOID:0000000009177523

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

REVERSE PROHIBIT CONTROL

DTC Inspection Priority Chart

INFOID:0000000009177524

If multiple malfunction codes are detected at the same time, check each code according to the DTC check pri-

ority list below. 

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.

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

The reverse brake is controlled to avoid becoming engaged when the selector lever is set in “R” position while 
driving in forward direction at more than the specified speed.

Vehicle behavior in 
control 

If the selector lever is put at “R” position when driving with the forward gear, the gear becomes neutral, not 
reverse. 

Normal return condi-
tion

The control returns to normal control when the vehicle is driven at low speeds. (The reverse brake becomes 
engaged.)
