Description and operation
• |
Automatic transaxle system relies on various measurement data to determine
the current control status and extrapolate the necessary compensation
values.extrapolate the necessary compensation values.
|
• |
These values are used to control the actuators and achieve the desired
control output.
|
• |
If a problem with the drivetrain, including the transaxle, has been
identified, perform self-diagnosis and basic transaxle inspection (oil
and fluid inspection) and then check the control system's components
using the diagnosis tool.

Repair procedures
1. |
Overview and purpose of learning
1) |
The purpose is to ensure the initial operation safety by correcting
the oil pressure differences between transmissions.
|
2) |
For relearning of TCM, process relearning by deleting existing
contents using diagnostic tool when there is shift shock at
gears 1-2-3-4-5-6.
|
|
2. |
In the following case, TCM learning is required.
1) |
Automatic transaxle assembly replacement
|
|
3. |
TCM learning procedure
1) |
Condition : ATF temperature 35 - 95°C (95 - 203°F)
|
2) |
Stop learning
- Repeat the shift pattern shown below five times or more with
the brake stepped on.
|
3) |
Driving relearn
- Maintain the throttle open to a constant level with the gear
in D position and increment from 1st to 5th gear within 1500
~ 2500 RPM of engine and decelerate slowly.
With (ON, throttle opening: 0%), decrement from 6th to 1st gear.
- Upshift throttle opening : 15 - 35% (a proper value for making
upshift within 1500 - 2500RPM of engine)

Transaxle Control Module (TCM). Description and operation
• |
Monitoring the vehicle's operating conditions to determine the optimal
gear setting.
|
• |
Performing a gear change if the current gear setting differs from the
identified optimal gear setting.
|
• |
Determining the need for damper clutch (D/C) activation and engages
the clutch accordingly.
|
• |
Calculating the optimal line pressure level by constantly monitoring
the torque level and adjusts the pressure accordingly.
|
• |
Diagnosing the automatic transaxle for faults and failures.

Transaxle Control Module (TCM). Repair procedures
1. |
TCM ground circuit test : Measure the resistance between TCM and chassis
ground.
(Inspect the terminal connected to the chassis ground with the back
of harness connector as the inspection point of TCM side.)
Specification : Below 1Ω
|
|
2. |
TCM connector test : Disconnect the TCM connector and visually check
the ground terminals on TCM side and harness side for bent pins or poor
contact pressure.
|
3. |
If problem is not found in Steps 1 and 2, the TCM could be faulty.
If so, replace the TCM with a new one, and then check the vehicle again.
If the vehicle operates normally then the problem was likely with the
TCM.
|
4. |
Reinspection of original TCM : Install the original TCM (probably broken)
into a known-good vehicle and check the vehicle. If the problem occurs
again, replace the original TCM with a new one.
If the problem does not reoccur, this is an intermittent problem and
other part may be faulty.
|
1. |
Perform the oil pressure characteristics backup procedure using the
diagnostic tool when replacing with a new TCM.
|
2. |
Turn ignition switch OFF and disconnect the negative (-) battery cable.
|
3. |
Remove the air cleaner assembly.
(Refer to Engine Mechanical System - "Air Cleaner")
|
4. |
Remove the TCM.
1) |
Disconnect the TCM connector (A).
|
2) |
Pull the clip (A) and then removing the TCM (B).
|
|
1. |
To install, reverse the removal procedure.
|
2. |
Oil-pressure characteristics input (TCM exchange)
• |
In order to avoid any problem including sense of starting
delay of the transaxle and shock at acceleration and
vehicle start, make sure to process learning for TCM
after replacing the transaxle / TCM.
(Refer to Automatic Transaxle Control System - "Repair
Procedures")
|
• |
Since TCM and ECM are integrated, perform the procedures
related in the ECM after replacing the TCM.
(Refer to Engine Control / Fuel System - "Engine Control
Module (ECM)")
|
|
|
Transaxle Oil Temperature Sensor. Description and operation
• |
Transaxle oil temperature sensor monitors the automatic transaxle fluid's
temperature and conveys the readings to TCM.
|
• |
It is an NTC (Negative Thermal Coefficient) sensor whose resistance
has an inversely proportional relationship with the temperature level.
|
• |
Data produced by this sensor is used to identify damper clutch activation
and deactivation zones within the low temperature and high temperature
range and to compensate hydraulic pressure levels during gear changes.

Transaxle Oil Temperature Sensor. Repair procedures
•
|
Refer to the DTC manual for the check procedure.
|
|
•
|
Be careful not to damage the parts located under the vehicle
(floor under cover, fuel filter, fuel tank and canister) when
raising the vehicle using the lift.
(Refer to General Information - "Lift and Support Points")
|
•
|
When Diagnostic Trouble Codes (DTC) is on, perform the following
procedure to replace it.
|
•
|
Automatic transaxle is composed of delicate components. Be careful
not to cause any damage on the component in the course of assembly
and disassembly.
|
•
|
Maintain clean condition so that foreign substance does not
get into the automatic transaxle.
|
•
|
Use a coated apron, latex gloves, and stainless tray to prevent
foreign substance from getting into the transaxle.
|
•
|
Automatic transaxle fluid (ATF) can be reused. Collect it using
a clean 10-liter beaker.
|
|
1. |
Turn ignition switch OFF and disconnect the negative (-) battery cable.
|
2. |
Remove the battery.
(Refer to Engine Electrical System - "Battery")
|
3. |
Remove the air cleaner assembly and air duct.
(Refer to Engine Mechanical System - "Air Cleaner")
|
4. |
Disconnect the solenoid valve connector (A).
|
5. |
Loosen the bolt and then removing the wiring bracket (A).
|
6. |
Separate the air bleeder hose (B).
