Fail-safe
INFOID:0000000009464219
TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of
the main electronically contro lled 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-sa fe mode. At this time, check the DTC code and perform
inspection and repair according to the malfunction diagnosis procedures.

Protection Control INFOID:0000000009464220
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
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.

REVERSE PROHIBIT CONTROL
DTC Inspection Priority ChartINFOID:0000000009464221
If multiple malfunction codes are detected at the same
time, check each code according to the DTC check pri-
ority list below.
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 retu rn 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 retu rn condi-
tion The control returns to normal control when the vehicle is driven at low speeds. (The reverse brake becomes
engaged.)

tained from 35 to 45 °C (95 to 113 °F).
• During adjustment of the CVT fluid level, check that the engine speed is maintaining 500 rpm.
• Use caution when looking into the drain hole as th ere is a risk of dripping fluid entering the eye.

2. Start the engine.
3. Adjust the CVT fluid temperature to be approximately 40 °C (104 °F).
NOTE:
The CVT fluid is largely affected by temperature. Therefore be sure to use CONSULT and check the
“FLUID TEMP” under “TRANSMISSION” in “Data Monitor” while adjusting.
4. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “DS”, and shift it to the “P” position.

1. Turn ON the ignition switch with the shift selector at the “P” position.
2. Press the shift selector button with the brake pedal depressed, and confirm that the shift selector can be
moved to positions other than “P”. Also confirm that movement is not allowed from the “P” position to other
position without depressing the brake pedal.
3. Move the shift selector and check for “excessive effort”, “sticking”, “noise” or “rattle”.
4. Confirm that shift selector stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the shift selector is in matches the position shown
by the transaxle body.
5. Make sure that the shift selector is moved to all the shift posi- tions in the manner shown.
• (A): Press shift selector button to operate shift selector, while depressing the brake pedal.
• (B): Press shift selector button to operate shift selector.
• (C): Shift selector can be operated without pressing the shift selector button.
6. When the shift selector button is pressed without applying for- ward/backward force to the shift selector at “P”, “R”, “N”, “D” or
“Ds” positions, there should be no “sticking” on the shift selector
button operation.
7. Check that the back-up lamps do not illuminate when the shift selector is in the “P” position.
8. Check that the engine can be started with the sh ift selector in the “P” and “N” positions only.
9. Check that the transaxle is locked completely when the shift selector is in the “P” position.
AdjustmentINFOID:0000000009464235
1. Shift the shift selector to the “P” position.
CAUTION:
Turn wheels at least a quarter turn and be certain the park position mechanism is fully engaged.
2. Loosen the control cable nut. CAUTION:
Do not apply force to the manual lever.
3. Position the manual lever in the “P” position.
4. Tighten the control cable nut to specified torque. Refer to TM-
380, "Exploded View".
CAUTION:
Hold manual lever when tightening.
