2. FEATURES
1) Advantages
Early Downshift with Hard Braking and Skip Shifts
When heavy braking is detected, the transaxle downshifts early and skips gears to provide increased
engine braking to provide gear selection for tip-in.
Gear Hold going Uphill/Downhill
If the accelerator pedal is released when traveling uphill, upshifts are prevented to reduce busyness on
grades. If the accelerator pedal is released when traveling downhill, upshifts are prevented to enhance
engine braking.
Drive and Reverse Engagement
A soft engagement feature avoids harsh take up of drive when selecting Drive or Reverse. This is
achieved by limiting engine speed and engine torque which results in a rapid, but progressive
engagement of either Drive or Reverse when moving from the Park or Neutral positions. Drive and
Reverse engagements from either Park or Neutral are performed in less than 2.2 seconds. There is no
drive engagement prevention strategy implemented on the transaxle system as there is sufficient engine
strategy to protect the system. However, reverse engagement is prevented until engine speed is less
than 1,400 rpm and the accelerator pedal position is less than 12% and vehicle speed is less than 10
km/h.
Converter Clutch Lock-Up In All Gears
The transaxle features converter clutch lock-up in all gears. This feature provides improved fuel economy
and vehicle performance. It also improves transaxle cooling efficiency when towing heavy loads at low
speeds, e.g. in city driving or hill terrain.
Embedded Memory Module (EMM)
The embedded memory module (EMM) is
transaxle assembly to ensure refined shift quality.
The EMM is used to store data such as valve body
calibration data and valve body serial number.
Upon installation, the TCU will download the data
from the EMM and utilize this data in the operation
of the transaxle.

2) Transaxle Cooling
The transaxle cooling system ensures rapid warm-up and constant operating temperature resulting in
reduced fuel consumption and refined shift quality.
It also includes a cooler by-pass within the hydraulic system to allow sufficient lubrication to the transaxle
drivetrain in the event of a blockage in the transaxle cooler.
3) Shift Strategy
Gear Change
Transaxle gear change is controlled by the
TCU. The TCU receives inputs from various
engine and vehicle sensors to select shift
schedules and to control the shift feel and
torque converter clutch (TCC) operation at each
gear change.
Coast down
Coast down down shifts occur at 0% pedal
when the vehicle is coasting down to a stop.
Torque Demand
Torque demand down shifts occur
(automatically) when the driver demand for
torque is greater than the engine can provide at
that gear ratio. If applied, the transaxle will
disengage the TCC to provide added
acceleration.

3) Shift Map Selection
The driver can manually select between normal (S) and winter modes (W) via the mode switch.
Depending on the transaxle temperature, uphill and downhill grades and altitude, shift maps will be
selected by the TCU to suit the driving conditions. The following maps are available.
Standard (Normal) Mode
Normal Mode is selected when the lever is in the D position with the mode switch in the normal (S)
position and the transaxle is within normal temperature ranges. Shift schedule points are optimised for
fuel efficiency and general driving conditions.
Uphill and Downhill Mode
In this mode, depending on the load of the vehicle, adaptive shift maps are selected to progressively
adjust the shift points and torque converter lock points.
Altitude Mode
Shift points are automatically adjusted at higher altitudes to compensate for changes in engine torque
where the torque produced by the engine is greatly reduced by the effects of reduced barometric
pressure and temperature.
Winter (W) Mode
When winter mode is selected, starting in second gear is facilitated and the WINTER mode indicator
light is switched ON. To prevent wheel spin on slippery surfaces, the transmission will not allow first gear
unless manually overridden.
Warm up Schedule
Hot Mode
converter lock-up is increased to prevent heat generation by the torque converter.
Activation of the hot mode inhibits other transmission performance features including uphill and downhill
compensation and altitude compensation. Some degradation in shift feel may be experienced as the
torque converter is not unlocked during shifting.
Cruise Control Mode
When cruise control is activated the engine ECU may request the transaxle to downshift under trailing
throttle conditions to increase engine braking.
the electrical radiator fans are switch ON
the engine torque will be reduced and the W light on the instrument cluster will flash
protection.

3. DUAL MASS FLYWHEEL (DMF)
The dual mass flywheel (DMF) is of having a mass divided into two halves.
While one mass is connected to the engine crankshaft, which is affected by the mass moment of inertia
of the engine, the other mass is affected by one of the transmission.
The divided dual masses are connected to the coil spring and damping system internally.
The DMF has the following benefits:
Reducing fuel consumption by lowering engine speed
Reducing rattling noise and vehicle vibration in all driving ranges
Reducing synchronization wear
Facilitating gear change
Protecting power train parts by preventing excessive load from being delivered -

Hydraulic power steering Electric power steering
1. OVERVIEW
The electric power steering, EPS, does not have any belt-driven steering pump constantly running, so it
is lightweight and the motor consumes energy only when the steering wheel is turned by the driver, and
this leads to improvement in fuel efficiency. Also, the elimination of a belt-driven pump and its
accessories greatly simplifies manufacturing and maintenance. While offering these benefits, as it does
not contain any steering oil, the environment is not polluted both when the steering system is produced
and discarded.
In other words, the electric power steering (EPS) system uses the electric motor to assist the steering
force. It functions independently regardless of whether the engine is running or not, unlike the existing
hydraulic power steering.
The EPS system generates an assist steering force variably depending on the driving conditions by
controlling the motor's operation, based on the input signals from the sensors such as torque sensor and
angle sensor. In turn, the EPS receives the torque signal by the driver's movements of the steering
wheel, as well as the vehicle speed, and uses the motor to determine the assist torque. The EPS
controls the motor for this. Another features of EPS are fail-safe function, diagnosis function,
communication function between units and interface function for external diagnostic device.
The EPS system components such as the torque sensor, steering angle sensor, fail-safe relay, etc. are
located in the steering column and EPS unit assembly.
Advantages:
Assurance of improved steering
Provides optimal steering force according to the
vehicle speed
Enhanced steering stability while driving at high

2. LAYOUT 1. OVERVIEW
The TPMS is used to reduce the accident rate, enhance driving stability and avoid an unnecessary fuel
consumption and tire wear by monitoring the tire pressure and temperature to inform the driver of tire
pressure information and its status through the instrument cluster. The wheel module fitted in the tire
transmits the internal data for the tire to the TPMS ECU periodically through the wireless transmission.
The TPMS ECU can detect the positions of the wheel modules fitted to each wheel automatically and
sends the signal on tire condition through the CAN line to the instrument cluster so that the driver can
identify the wheel module in question.
