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.

Protection Control INFOID:0000000012431035
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
DTC Inspection Priority ChartINFOID:0000000012431036
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.
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.
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.)

LU-7, "Inspection".
2. Check for CVT fluid leaks. Refer to TM-228, "
Inspection".
3. Drive for about 10 minutes to warm up the vehicle so that the CVT fluid temperature is 50 to 80°C (122 to
176° F).

NARROWING-DOWN MALFUNCTIONING PARTS
Line pressure : TM-265, "Line Pressure"
Judgment Possible cause
Idle speed Low for all positions
(“P”, “R”, “N”, “D”, “L”)
Possible causes include malfunctions in the pressure supply system and low oil pump output.
For example:
• Oil pump wear
• Damage of chain and sprocket
• Pressure regulator valve or plug sticking or spring fatigue
• Oil strainer
⇒ oil pump ⇒ pressure regulator valve passage oil leak
• Engine idle speed too low
Only low for a specific
position Possible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
High Possible causes include a sensor malfunction or malfunction in the line pressure adjustment
function.
For example:
• Accelerator pedal position signal malfunction
• CVT fluid temperature sensor malfunction
• Line pressure solenoid malfunction (sticking in OFF state, filter clog, cut line)
• Pressure regulator valve or plug sticking
Stal l s pe ed Line pressure does not
rise higher than the line
pressure for idle.
Possible causes include a sensor malfunction or malfunction in the pressure adjustment func-
tion.
For example:
•TCM malfunction
• Line pressure solenoid malfunction (shorting, sticking in ON state)
• Pressure regulator valve or plug sticking
The pressure rises, but
does not enter the
standard position. Possible causes include malfunctions in the pressure supply system and malfunction in the pres-
sure adjustment function.
For example:
• Oil pump wear
• Line pressure solenoid malfunction (sticking, filter clog)
• Pressure regulator valve or plug sticking
Only low for a specific
position Possible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.

engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly push down and
turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down
and turning it all the way.
CAUTION:
Perform these steps after the engine cool ant temperature has cooled sufficiently.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.
1. Remove the hose clamp and pull out the water hose A.
2. Remove the hose clamp and pull out the water hose B.

TRANSMISSION ASSEMBLY
INSPECTION AFTER INSTALLATION
Check the following items:
• For CVT position, refer to
TM-232, "
Inspection".
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
• Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.
ADJUSTMENT AFTER INSTALLATION
• Adjust the CVT fluid level. TM-229, "Adjustment".
• Perform "ADDITIONAL SERVICE WHEN REPL ACING TRANSAXLE ASSEMBLY". Refer to TM-127,
"Description".
