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.)

ADDITIONAL SERVICE WHEN REPLACING TCM
DescriptionINFOID:0000000009464010
Always perform the following items when the TCM is replaced.
SAVING AND WRITING OF TCM DATA• TCM performs accurate control by retrieving data (inher
ent characteristic value) of each solenoid. For this
reason, it is necessary to save data of current TCM in CONSULT before replacing the TCM. After this, the
saved data must be written in new TCM.
Work ProcedureINFOID:0000000009464011
CAUTION:
When replacing TCM together with transaxle assembly, perform “ADDITIONAL SERVICE WHEN
REPLACING TRANSAXLE ASSEMBLY”. Refer to TM-81, "Work Procedure"
.
1.SAVE THE TCM DATA
NOTE:
Save necessary data stored in TCM in CONSULT according to the following instructions:
1. Turn ignition switch OFF and wait for 10 seconds.
2. Turn ignition switch ON.
3. Select “Work Support” in “TRANSMISSION”.
4. Select “READ IP CHARA - REPLACEMENT TCM”.
5. Import data according to the in structions on the CONSULT screen.
>> GO TO 2.
2.REPLACE THE TCM
1. Turn ignition switch OFF and wait for 10 seconds.
2. Replace the TCM. Refer to TM-183, "Removal and Installation"
.
>> GO TO 3.
3.WRITE THE TCM DATA
NOTE:
Write data saved in CONSULT into a new TCM according to the following instructions:
1. Turn ignition switch OFF and wait for 10 seconds.
2. Turn ignition switch ON.

ADDITIONAL SERVICE WHEN RE PLACING TRANSAXLE ASSEMBLY
DescriptionINFOID:0000000009464012
Perform the following work after the transaxle assembly is replaced.
ERASING AND WRITING TCM DATA• TCM performs accurate control by retrieving data (inher ent characteristic value) of each solenoid. For this
reason, after replacing transaxle assembly, it is nec essary to erase data stored in TCM and write new data.
ERASING OF CVT FLUID DEGRADATION LEVEL DATA • TCM records the degradation level of the CVT fluid calc ulated from the vehicle driving status. Therefore, if
the transaxle assembly is replaced, it is necessary to erase the CVT fluid degradation level data recorded by
TCM.
Work ProcedureINFOID:0000000009464013
1.CHECK THE SERIAL NUMBER (PART 1)
Write down the serial number of new transaxle assembly.
>> GO TO 2.
2.CHECK THE SERIAL NUMBER (PART 2)
1. Turn ignition switch ON.
2. Insert the attached CD into CONSULT.
3. Select “Work Support” in “TRANSMISSION”.
4. Select “WRITE IP CHARA - REPLACEMENT AT/CVT”.
5. Check that the serial number displayed on CO NSULT screen and those written in the memo agree.
CAUTION:
Never perform writing procedure.
6. Go back to MENU of “Work Support”.
>> GO TO 3.
3.INITIALIZE TCM
1. Set parking brake.
2. Select “ERASE MEMORY DATA”.
3. Touch “Start” according to the instructions on the CONSULT screen.
Is
“COMPLETED” displayed?
YES >> GO TO 4.
NO >> Turn ignition switch OFF and wait for a mi nimum of 10 seconds then perform the work again.
