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
×

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 Instruction 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.
