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”.

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.

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.
