INSPECTION AFTER INSTALLATION
• Check the operation of the control linkage. Refer to TM-21, "Inspection".
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks at connection points.
• Start engine. With engine speed increased, check again for fuel leaks at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no lea ks of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.

< SYSTEM DESCRIPTION >[CVT: RE0F11A]
SYSTEM
Gear shifting is performed in all shifting ranges from the lowest to the
highest gear ratio.
D Position (OD OFF)
The gear ratio is generally high by limiting the shifting range on the
high side, and this always generates a large driving power.
L Position
By limiting the shifting range only to the lowest of the gear ratio, a
large driving force and engine brake are obtained.
Hill Climbing And Descending Control
If a downhill is detected with the accelerator pedal is released, the system performs dow
nshift to increase the
engine brake force so that vehicle may not be accelerated more than necessary. If a climbing hill is detected,
the system improves the acceleration performance in re-acceleration by limiting the gear shift range on the
high side.
NOTE:
For engine brake control on a downhill, the control can be stopped with CONSULT.
Control In Acceleration
From change of the vehicle speed or accelerator pedal posit ion, the acceleration request level of the driver or
driving scene is evaluated. In start or acceleration during driving, the gear shift characteristics with linearity of
revolution increase and vehicle speed increase are gained to improve the acceleration feel.

trol, idle neutral control is stopped when any of the following conditions is not met or idle neutral control contin-
ues 30 seconds.

lowing conditions.
• Engine coolant temperature and CVT fluid temperature are the specified temperature or more, or the speci-
fied temperature or less.
• When a transaxle malfunction occurs.
• When the vehicle detects DTC and is in the fail-safe mode.
• When idle speed increases due to heavy electric load*. *: When any one of rear window defogger switch, A/C s witch, headlamp, fog lamp is turned ON. In addition,
when the steering wheel is operated.

ADDITIONAL SERVICE WHEN REPL ACING CONTROL VALVE OR TRAN-
SAXLE ASSEMBLY
DescriptionINFOID:0000000012431044
When replacing the control valve or transaxle assembly , perform the following work. For work procedure, refer
to TM-130, "
Work Procedure".
ERASING, LOADING AND STORING OF CALIBRATION DATA• The TCM acquires calibration data (individual characteristic value) of each solenoid that is stored in the
ROM assembly (in the control valve). This enables the TCM to perform accurate control. For this reason,
after the control valve or transaxle assembly is replaced, it is necessary to erase the calibration data previ-
ously stored in TCM, to load new calibration data, and to store them.
ERASING THE LEARNED VALUE DATA• TCM learns indicated pressure for appropriate control of the transaxle assembly and records the learned
values. For this reason, the leaned values stored in TCM must be erased after replacing a transaxle assem-
bly.
ERASING CVT FLUID DEGR ADATION LEVEL DATA • TCM records the degradation level of the CVT fluid calculated from the vehicle driving status. Therefore, if
the transaxle assembly is replaced, it is necessary to erase the CVT fluid degradation level data recorded by
TCM.
Work ProcedureINFOID:0000000012431045
1.INITIALIZE TCM
With CONSULT
1. Set parking brake.
2. Turn ignition switch ON.

“COMPLETED” displayed?
YES >> GO TO 2.
NO >> Turn the ignition switch OFF and wait for a minimum of 10 seconds then perform the work again.
2.CHECK AFTER TCM IS INITIALIZED
With CONSULT
1. Turn ignition switch OFF with the selector lever in “R” position and wait for 10 seconds or more.
2. Turn ignition switch ON with the selector lever in “R” position. CAUTION:
Never start the engine.
3. Select “Special function” in “TRANSMISSION”.
4. Select “CALIB DATA”.
