ENGINE BRAKE ADJ. Although there is no malfunction on the transaxle and the CVT system, if a customer
make a complaint like “I do not feel comfortable with automatic operation of the engine
brake on downhill”, the engine brake may be cancelled with “engine brake adjust-
ment”.
CONFORM CVTF DETERIORTN Check the degradation level of the CVT fluid under severe conditions.
G SENSOR CALIBRATION Compensate the G sensor.
ERASE CALIBRATION DATA Erase the calibration data memorized by TCM.
ERASE LEARNING VALUE Erase the learning value me morized by TCM.
ERASE MEMORY DATA Perform “erasing of the calibration data” and “erasing of the learned value” at the same
time.
CLUTCH POINT LEARNING* Allow learning of the clutch engagement point of the auxiliary gearbox for TCM.
ENGINE BRAKE LEVEL
ON : Turn ON the engine brake control.
OFF : Turn OFF the engine brake control.
CVTF degradation level data
210,000 or more : Replacement of the CVT fluid is required.
Less than 210,000 : Replacement of the CVT fluid is not required.

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.)

INSPECTION
1. Check the engine oil level. Replenish if necessary.
2. Check for leak of the CVT fluid. 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).
4. Be sure to apply the parking brake and block the tires.
5. Start the engine, depress the brake pedal and put the selector lever to the D position.
6. While depressing the brake pedal, depress the accelerator pedal gradually.
7. Read the stall speed quickly. Then, release your foot from the accelerator pedal quickly. CAUTION:
Do not depress the accelerator pedal fo r 5 seconds or more during the test.
8. Place the selector lever in the N position.
9. Cool the CVT fluid. CAUTION:
Run the engine with the idle speed for at least 1 minute.
10. Put the selector lever to the R position and perform Step 6 to Step 9 again.
