CVT CONTROL SYSTEM : Protection Control
INFOID:0000000012431020
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.

Normal return condi-
tion Torque returns to normal by positioning the selector lever in a range ot

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.

SYSTEM
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.

CVT POSITION
InspectionINFOID:0000000012431050
1. Turn ON the ignition switch with the shift selector in the "P" position.
2. Press the shift selector handle button with the brak e pedal depressed, and confirm that the shift selector
can be moved from the "P" position. Also confirm that shift selector will not move from the "P" 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. The method of operating the shift selector to individual positions correctly should be as shown.
• (A): Press shift selector button to operate shift selector, whiledepressing the brake pedal.
• (B): Press shift selector button to operate shift selector.
• (C): Shift selector can be operated without pressing shift selector button.
6. When the shift selector handle button is pressed without apply- ing forward/backward force to the shift selector at “P”, “R”, “N”
and “D” positions, there should be no “sticking” of the button.
7. Confirm the back-up lamps illuminate only when shift selector is placed in the “R” position. Confirm the back-up lamps do not illu-
minate when the shift selector is pushed toward the “R” pos ition side when shift selector is in the “P” or “N”
position.
8. Check that the engine can be started only when the shift selector is in the “P” and “N” positions.
9. Check that the transaxle is locked when t he shift selector is in the "P" position.
AdjustmentINFOID:0000000012431051
1. Move the shift selector to the “P” position.
CAUTION:
Rotate the wheels at least a quarter turn and be certain the transaxle is locked in the "P" position.
2. Remove nut (A) and set manual lever (B) to the “P” position. CAUTION:
Do not apply force to the manual lever.
3. Tighten nuts to the specified torque. Refer to TM-234, "
Exploded
View".
CAUTION:
Do not move the manual lever when tightening.

CAUTION:
Be careful of the driving speed.
1.PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
1. Start the engine.
2. Shift the selector lever to “D” position.
3. Drive the vehicle at a constant velocity of 40 km/h (25 MPH) at lease for 10 seconds.
CAUTION:
At the same time, the accelerator pedal angle must be maintained constant.
4. Stop the vehicle.
5. Check the first trip DTC.
Is
“P0846”detected?
YES >> Go to TM-175, "Diagnosis Procedure".
NO >> INSPECTION END
