COMPONENT PARTS
• The principle of the linear solenoid valve utilizes the fa
ct that the force pressing on the valve spool installed
inside the coil increases nearly in proportion to the current . This allows it to produce a fluid pressure that is
proportional to this pressing force.
• The N/L (normal low) type does not produce hydr aulic control when the coil is not energized.
CVT CONTROL SYSTEM : Line Pressure Solenoid ValveINFOID:0000000009463975
• The line pressure solenoid valve is installed to control valve.
• The line pressure solenoid valve controls the pressure regulator valve. For information about the pressure
regulator valve, refer to TM-27, "TRANSAXLE : Component Description"
.
• The line pressure solenoid valve uses the linear solenoid valve [N/H (normal high) type]. NOTE:
• The principle of the linear solenoid valve utilizes the fa ct that the force pressing on the valve spool installed
inside the coil increases nearly in proportion to the current . This allows it to produce a fluid pressure that is
proportional to this pressing force.
• The N/H (normal high) produces hydraulic control when the coil is not energized.
CVT CONTROL SYSTEM : Overdrive Control SwitchINFOID:0000000009463976
• The overdrive control switch is inst alled to the selector lever knob.
• If the overdrive control switch is pressed when the O/D OFF indicator lamp on the combination meter is not
lit, the status changes to overdrive OFF and the O/D OFF indicator lamp illuminates.
• If the overdrive control switch is pressed when the O/ D OFF indicator lamp on the combination meter is lit,
the overdrive OFF status is canceled and the O/D OFF indicator lamp turns off.
CVT CONTROL SYSTEM : O/D OFF Indicator LampINFOID:0000000009463977
• O/D OFF indicator lamp is positioned on the combination meter.
• The O/D OFF indicator lamp illuminates when the overdrive function is deactivated (O/D OFF).
• For checking the bulb, this lamp turns on for a cert ain period of time when the ignition switch turns ON,
andthen turns off.
CVT CONTROL SYSTEM : Sh ift Position IndicatorINFOID:0000000009463978
TCM transmits shift position signal to combination meter via CAN communication. The actual shift position is
displayed on combination meter according to the signal.

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 t he 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 slight ly 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 indica tes 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 shif ting calculated in the control unit is completed.

INFOID:0000000009464002
TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of
the main electronically contro lled input/output parts is damaged.
If the vehicle shows following behaviors including “poor acceleration”, a malfunction of the applicable system
is detected by TCM and the vehicle may be in a fail-sa fe mode. At this time, check the DTC code and perform
inspection and repair according to the malfunction diagnosis procedures.

Question sheetINFOID:0000000009464009
DESCRIPTION
There are many operating conditions that may cause a malfunction
of the transmission parts. By understanding those conditions prop-
erly, a quick and exact diagnosis can be achieved.
In general, perception of a problem varies depending on individuals.
Ask the customer about his/her concer ns carefully. It is important to
understand the phenomenon or status. To systemize all the informa-
tion for the diagnosis, prepare the question sheet referring to the
question points.
In some cases, multiple conditions that appear simultaneously may
cause a DTC to be detected.

CVT FLUID
19. Repeat steps 8 to 18 (one time).
20. Tighten the drain plug to the specified torque. Refer to TM-186, "Exploded View"
.
21. Remove the overflow plug.
22. Install the charging pipe set (KV311039S0) into the overflow plug hole. CAUTION:
Tighten the charging pipe by hand.
23. Install the ATF changer hose to the charging pipe. CAUTION:
Press the ATF changer hose all the way onto the charging pipe until it stops.
24. Fill approximately 3 liter (2-5/8 lmp qt) of the CVT fluid.
25. Remove the ATF changer hose and charging pipe, then install the overflow plug. NOTE:
Perform this work quickly because CVT fluid leaks.
26. Lift down the vehicle.
27. Start the engine.
28. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “DS”, and shift it to the “P” position.
NOTE:
Hold the lever at each position for 5 seconds.
29. Check that the CONSULT “Data Monitor” in “FLUID TEMP” is 35 °C (95 °F) to 45 °C (113 °F).
30. Lift up the vehicle.
31. Remove the overflow plug and confirm that the CV T fluid is drained from the overflow plug hole.
CAUTION:
Perform this work with the vehicle idling.
NOTE:
If the CVT fluid is not drained, refer to “Adjustment” and refill with the CVT fluid.
32. When the flow of CVT fluid slows to a drip, tighten the overflow plug to the specified torque. Refer to TM-
186, "Exploded View".
CAUTION:
Never reuse O-ring.
33. Lift down the vehicle.
34. Select “Data Monitor” in “T RANSMISSION” using CONSULT.
35. Select “CONFORM CVTF DETERIORTN”.
36. Select “Erase”.
37. Stop the engine.
AdjustmentINFOID:0000000009464015
CAUTION:
• During adjustment of the CVT fluid level, check CO NSULT so that the oil temperature may be main-
tained from 35 to 45 °C (95 to 113 °F).
• During adjustment of the CVT fluid level, check that the engine speed is maintaining 500 rpm.
• Use caution when looking into the drain hole as th ere is a risk of dripping fluid entering the eye.
1. Check that the selector lever is in the “P ” position, then completely engage the parking brake.
2. Start the engine.
3. Adjust the CVT fluid temperature to be approximately 40 °C (104 °F).
NOTE:
The CVT fluid is largely affected by temperature. Therefore be sure to use CONSULT and check the
“FLUID TEMP” under “TRANSMISSION” in “Data Monitor” while adjusting.
4. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “DS”, and shift it to the “P” position.
