< SYSTEM DESCRIPTION >
[CVT: RE0F10G]
DIAGNOSIS SYSTEM (TCM)
*: Not applicable but displayed.
WORK SUPPORT
*: This item does not use.
Engine brake adjustment
Check the degradation level of the CVT fluid.
ELECTRIC OP DUTY
(%)
Displays the command signal value (duty) of the electric oil pump transmitted from
TCM.
E-OP DUTY MON
(%)
Monitors the status signal value (duty) transmitted from the electric oil pump and dis-
plays the monitored value.
ELECTRIC OP RELAY
(On/Off)
Displays the command status from TCM to the electric oil pump relay.
E-OP RELAY MON
(On/Off)
Monitors the command status from TCM to the oil pump relay and displays the mon-
itored value.
CVT-B
• Displays CVT fluid temperature count.
• This monitor item does not use.
CVT-A
• Displays CVT fluid temperature count.
• This monitor item does not use.
G SENSOR
(V)
Displays the signal voltage of the G sensor.

Description
CONFORM CVTF DETERIORTN
Checks the degradation level of the CVT fluid under severe conditions.
G SENSOR CALIBRATION
Compensates the G sensor.
ERASE LEARNING VALUE*
Erases learning value memorized by TCM.
ENGINE BRAKE ADJ.
Although there is no malfunction on the transaxle and the CVT system, if a cus-
tomer 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 adjustment”.
ELECTRIC O.P. AIR BLEEDING
Bleed air from the electric oil pump.
WRITE IP CHARA - REPLACEMENT AT/CVT
Writes IP characteristics when transaxle assembly is replaced.
READ IP CHARA - REPLACEMENT TCM
Reads IP characteristics when TCM is replaced.
WRITE IP CHARA - REPLACEMENT TCM
Writes IP characteristics when TCM is replaced.
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:0000000010622751
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.
