CVT CONTROL SYSTEM : Fail-safe
INFOID:0000000009644832
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:0000000009268087
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
CONTROL WHEN FLUID TEMPERATURE IS HIGH
TORQUE IS REDUCED WHEN DRIVING WITH THE REVERSE GEAR
REVERSE PROHIBIT CONTROL
LINE PRESSURE CONTROL

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.
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.)
