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 suitable for driving condition are determined based on the
accelerator pedal position, engine speed, primary pulley (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, oi l pressure, and overdrive control switch signal.
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 an oil pressure sensor and by feedback control.
SHIFT CONTROL
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.)

DESCRIPTION
• Controls for improvement of the transmission effici ency by engaging the torque converter clutch in the
torque converter and eliminating slip of the converter. Achieves comfortable driving with slip control of the
torque converter clutch.
• The oil pressure feed circuit for the torque converter clutch piston chamber is connected to the torque con-
verter clutch control valve. The torque converter clut ch control valve is switched by the torque converter
clutch solenoid valve with the signal from TCM. This contro ls the oil pressure circuit, which is supplied to the
torque converter clutch piston chamber, to the release side or engagement side.
• If the CVT fluid temperature is low or the vehicle is in fail-safe mode due to malfunction, lock-up control is
prohibited.
Lock-up engagement
In lock-up engagement, the torque converter clutch solenoi d valve makes the torque converter clutch control
valve locked up to generate the lock-up apply pressure. This pushes the torque converter clutch piston for
engagement.
Lock-up release condition
In lock-up release, the torque converter clutch solenoi d valve makes the torque converter clutch control valve
non-locked up to drain the lock-up apply pressure. This does not engage the torque converter clutch piston.

DIAGNOSIS SYSTEM (TCM)
SELF DIAGNOSTIC RESULTS
Display Item List
Refer to
TM-60, "DTC Index".
DTC at 1st trip and method to read DTC
• DTC (P0705, P0711, P0720, etc.) is specified by SAE J2012/ISO 15031-6.
• DTC and DTC at 1st trip are displayed on “Self Diagnostic results” of CONSULT.
When DTC is currently detected, “CRNT” is displayed. If “PAST” is displayed, it shows a malfunction
occurred in the past. The trip number of drive wit hout malfunction of concerned DTC can be confirmed with
“IGN counter” inside “FFD”.
• When the DTC at the 1st trip is detected, “1t” is displayed.
DTC deletion method
NOTE:
If the ignition switch is left ON after repair, turn O FF the ignition switch and wait for 10 seconds or more. Then,
turn the ignition ON again. (Engine stop)
1. Touch “TRANSMISSION” of CONSULT.
2. Touch “Self Diagnostic Result”.
3. Touch “Erase”. (DTC memorized in TCM is erased.)
IGN counter
The ignition counter is displayed in “FFD” and the number of times of satisfied “Driving condition A” is dis-
played after normal recovery of DTC. Refer to TM-41, "DIAGNOSIS DESCRIPTION : Counter System"
.
• If malfunction (DTC) is currently detected, “0” is displayed.
• After normal recovery, every time “Driving condition A” is satisfied, the display value increases from 1 → 2 →
3...38 → 39.
• When MIL turns OFF due to the malfunction and t he counter reaches 40, the DTC is erased.
NOTE:
The counter display of “40” cannot be checked.

Protection Control INFOID:0000000009464003
The TCM becomes the protection control status temporar ily 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 ChartINFOID:0000000009464004
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 sele
ctor 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.
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.)

Question sheetINFOID:0000000009464009
DESCRIPTION
There are many operating conditions that may cause a malfunction
of the transmission parts. By understanding those conditions prop-
erly, a quick and exact diagnosis can be achieved.
In general, perception of a problem varies depending on individuals.
Ask the customer about his/her concer ns carefully. It is important to
understand the phenomenon or status. To systemize all the informa-
tion for the diagnosis, prepare the question sheet referring to the
question points.
In some cases, multiple conditions that appear simultaneously may
cause a DTC to be detected.
