REVERSE PROHIBIT CONTROL
LINE PRESSURE CONTROL
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.
ControlWhen 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 ot
her than “R” position.
ControlThe 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.)

LINE PRESSURE CONTROL : System Description
INFOID:0000000012431021
SYSTEM DIAGRAM
DESCRIPTION
Highly accurate line pressure control (secondary pressure control) reduces friction for improvement of fuel
economy.
Normal Oil Pressure Control
Appropriate line pressure and secondary pressure su itable for driving condition are determined based on the
accelerator pedal position, engine speed, primary pulle y (input) speed, secondary pulley (output) speed, vehi-
cle speed, input torque, stop lamp switch signal, transmission range switch signal, lock-up signal, power volt-
age, target shift ratio, oil temperature and oil pressure.
Secondary Pressure Feedback Control
In normal oil pressure control and oil pressure control in shifting, highly accurate secondary pressure is deter-
mined by detecting the secondary pressure using a oil pressure sensor and by feedback control.

< SYSTEM DESCRIPTION >[CVT: RE0F11A]
SYSTEM
Gear shifting is performed in all shifting ranges from the lowest to the
highest gear ratio.
D Position (OD OFF)
The gear ratio is generally high by limiting the shifting range on the
high side, and this always generates a large driving power.
L Position
By limiting the shifting range only to the lowest of the gear ratio, a
large driving force and engine brake are obtained.
Hill Climbing And Descending Control
If a downhill is detected with the accelerator pedal is released, the system performs dow
nshift to increase the
engine brake force so that vehicle may not be accelerated more than necessary. If a climbing hill is detected,
the system improves the acceleration performance in re-acceleration by limiting the gear shift range on the
high side.
NOTE:
For engine brake control on a downhill, the control can be stopped with CONSULT.
Control In Acceleration
From change of the vehicle speed or accelerator pedal posit ion, the acceleration request level of the driver or
driving scene is evaluated. In start or acceleration during driving, the gear shift characteristics with linearity of
revolution increase and vehicle speed increase are gained to improve the acceleration feel.

IDLE NEUTRAL CONTROL : System DescriptionINFOID:0000000012431025
SYSTEM DIAGRAM
DESCRIPTION
If a driver has no intention of starting the vehicle in D position, TCM operates the low brake solenoid valve and
controls the oil pressure of the low brake to be low pressure. Therefore, the low brake is in the release (slip)
status and the power transmission route of transaxle is the same status as the N position. In this way, the tran-
saxle is in idling status and load to the engine can be reduced to improve fuel economy.

Provides idle neutral control when st
op/start operation is not performed.
Idle Neutral Control Start Condition
Idle neutral control is started when all of the following conditions are fulfilled. However, during idle neutral con-
trol, idle neutral control is stopped when any of the following conditions is not met or idle neutral control contin-
ues 30 seconds.
NOTE:
Stops or prohibits the idle neutral control when the TC M and ECM detect that the vehicle is in one of the fol-
lowing conditions.
• Engine coolant temperature and CVT fluid temperature are the specified temperature or more, or the speci-
fied temperature or less.
• When a transaxle malfunction occurs.
• When the vehicle detects DTC and is in the fail-safe mode.
• When idle speed increases due to heavy electric load*. *: When any one of rear window defogger switch, A/C s witch, headlamp, fog lamp is turned ON. In addition,
when the steering wheel is operated.

sis
INFOID:0000000012431028
NOTE:
“Start the engine and turn OFF the ignition switch after warm-up.” This is defined as 1 trip.
1 TRIP DETECTION DIAGNOSIS
When initial malfunction is detected, TCM memorize s DTC. In these diagnoses, some illuminate MIL and
some do not. Refer to TM-110, "
DTC Index".
2 TRIP DETECTION DIAGNOSIS
When initial malfunction is detected, TCM memorizes DTC of the 1st trip. MIL does not light at this stage. <1
trip>
If the same malfunction is detected again in next drivi ng, TCM memorizes DTC. When DTC is memorized, MIL
lights. <2 trip>
“Trip” of the “2 trip detection diagnosis” indicates the driving mode that executes self-diagnosis during driving.
×: Check possible —: Check not possible
DIAGNOSIS DESCRIPTION : DTC and DTC of 1st TripINFOID:0000000012431029
2 TRIP DETECTION DIAGNOSIS THAT ILLUMINATES MIL
• The DTC number of the 1st trip is the same as the DTC number.
• When a malfunction is detected at the 1st trip, TCM memo rizes DTC of the 1st trip. MIL does not light at this
stage. If the same malfunction is not detected at t he 2nd trip (conforming to necessary driving conditions),
DTC at the 1st trip is erased from TCM. If the same malfunction is detected at the 2nd trip, TCM memorizes
DTC and MIL lights at the same time.
• The DTC of the 1st trip is specified in Service $01 of SAE J1979/ISO 15031-5. Since detection of DTC at the
1st trip does not illuminate MIL, warning for a problem is not given to a driver.
• For procedure to delete DTC and 1st trip DTC from TCM, refer to TM-93, "
CONSULT Function".
• If DTC of the 1st trip is detected, it is necessary to check the cause according to the “Diagnosis flow”. Refer to TM-122, "
Flowchart of Trouble Diagnosis".
DIAGNOSIS DESCRIPTION : Malfunction Indicator Lamp (MIL)INFOID:0000000012431030
• TCM not only detects DTC, but also sends the MI L signal to ECM through CAN communication. ECM sends
the MIL signal to the combination meter through CAN communication according to the signal, and illumi-
nates MIL.
• For malfunction indicator lamp (MIL) description, refer to EC-57, "
DIAGNOSIS DESCRIPTION : Malfunction
Indicator Lamp (MIL)".

RELATION BETWEEN DTC AT 1ST TRIP/DTC/MIL AND DRIVING CONDITIONS (FOR 2 TRIP DE-
TECTION DIAGNOSIS THAT ILLUMINATES MIL)
• When initial malfunction is detected, TCM memorizes DTC of the 1st trip. MIL does not light at this stage.
• If the same malfunction is detected at the 2nd trip, TCM memorizes DTC and MIL lights at the same time.
• Then, MIL goes after driving the vehicle for 3 tr ips under “Driving condition B” without malfunction.
• DTC is displayed until 40 trips of “Driving condition A” are satisfied without detecting the same malfunction.
DTC is erased when 40 trips are satisfied.

DIAGNOSIS SYSTEM (TCM)
• When the self-diagnosis result is acceptable at the 2nd
trip (conforming to driving condition B), DTC of the
1st trip is erased.
COUNTER SYSTEM LIST
DRIVING CONDITION
Driving condition A
Driving condition A is the driving condition that provides warm-up.
In specific, count-up is performed when all of the following conditions are satisfied.
• Engine speed is 400 rpm or more.
• After start of the engine, the water temperature increased by 20 °C (36 °F) or more.
• Water temperature was 70 °C (158 °F) or more.
• The ignition switch was changed from ON to OFF.
NOTE:
• If the same malfunction is detected regardless of the driving condition, reset the A counter.
• When the above is satisfied without detecting t he same malfunction, count up the A counter.
• When MIL goes off due to the malfunction and the A counter reaches 40, the DTC is erased.
