< SYSTEM DESCRIPTION >

[CVT: RE0F11A]

DIAGNOSIS SYSTEM (TCM)

WORK SUPPORT

*: “Clutch point learning” can be selected, but do not use it.

Engine brake adjustment

Check the degradation level of the CVT fluid.

4WD-TCS SIGNAL

(On/Off)

• Displays the reception status of the engine torque

down request signal received through CAN communi-
cation.

• It is displayed although not equipped.

RANGE

Displays the gear position recognized by TCM.

M GEAR POS

Display the target gear of manual mode

G SEN SLOPE

(%)

Displays the gradient angle calculated from the G sensor
signal voltage.

ENGBRKLVL

(On/Off)

Displays the setting of “ENGINE BRAKE ADJ” in “Work
Support”.

PVIGN VOLT

(V)

Displays the backup voltage of TCM.

TRGT AUX GR RATIO

Displays the target gear ratio of the auxiliary gearbox cal-
culated from processing of gear shift control.

G SEN CALIBRATION

(YET/DONE)

Displays the status of “G SENSOR CALIBRATION” in
“Work Support”.

N IDLE STATUS

(On/Off)

Displays idle neutral status.

CVT-B

• Displays CVT fluid temperature count.
• This monitor item does not use.

Description

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 memorized 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.

Reference Value

INFOID:0000000009268102

CONSULT DATA MONITOR STANDARD VALUE

• In CONSULT, electric shift timing or lock-up timing, i.e. operation timing of each solenoid valve, is displayed.

Therefore, if there is an obvious difference between the shift timing estimated from a shift shock (or engine

speed variations) and that shown on the CONSULT, the mechanism parts (including the hydraulic circuit)

excluding the solenoids and sensors may be malfunctioning. In this case, check the mechanical parts follow-

ing the appropriate diagnosis procedure.

• Shift point (gear position) displayed on CONSULT slightly differs from shift pattern described in Service Man-

ual. This is due to the following reasons.

- Actual shift pattern may vary slightly within specified tolerances.

- While shift pattern described in Service Manual indicates start of each shift, CONSULT shows gear position

at end of shift.

- The solenoid display (ON/OFF) on CONSULT is changed at the start of gear shifting. In contrast, the gear

position display is changed at the time when gear shifting calculated in the control unit is completed.

NOTE:

The following table includes information (items) inapplicable to this vehicle. For information (items) applicable

to this vehicle, refer to CONSULT display items.
