SYSTEM
• The current flows separately into the termination circuits connected
across the CAN communication system and the termination cir-
cuits drop voltage to generate a potential difference between the
CAN-H line and the CAN-L line.
NOTE:
A signal with no current passage is called “Recessive” and one
with current passage is called “Dominant”.
• The system produces digital signals for signal communications, by using the potential difference.

• When registering new Key IDs or replacing the ECM that is not brand new, refer to CONSULT Immo-
bilizer mode and follow th e on-screen instructions.
• If multiple keys are attached to the key holder, separate them before work.
• Distinguish keys with unregistered key ID from those with registered ID.

Side curtain air bag modules are located above the vehicle headlin-
ing.Vehicles with side curtain air bags are equipped with labels on
the pillar upper finishers.
Front Seat Belt Pre-tensionerINFOID:0000000012430594
The seat belt pre-tensioner system with load limiter is installed for
both the driver's seat and the fr ont passenger's seat. It operates
simultaneously with the SRS air bag system in the event of a frontal
collision with an impact exceeding a specified level.
When the frontal collision with an im pact exceeding a specified level
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the belt pre-tensioner. Vehicle passengers
are securely restrained.
When passengers in a vehicle are thrown forward in a collision and
the restraining force of the seat belt exceeds a specified level, the
load limiter permits the specified ex tension of the seat belt by the
twisting of the ELR shaft, and a relaxation of the chest-area seat belt
web tension while maintaining force.
Air Bag Diagnosis Sensor UnitINFOID:0000000012430595
The air bag diagnosis sensor unit is located under the center con-
sole assembly. The air bag diagnosis sensor unit receives signals
from multiple SRS sensors and cont rols the deployment of the air
bags. The deployment of the air bags depends on the type and
severity of the collision. The air bag diagnosis sensor unit has self-
diagnosis capability through the us e of the CONSULT as well as
flash codes displayed by the air bag warning lamp.

DescriptionINFOID:0000000012430674
CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle
multiplex communication system with high data communication speed and excellent error detection ability.
Many electronic control units are equipped into vehicl es, and each control unit shares information and links
with other control units during operation. With CAN co mmunication, control units are connected with two com-
munication lines (CAN-H line, CAN-L line) allowing a hi gh rate of information transmission with less wiring.
Each control unit transmits and receives data but selectively reads required data only. Refer to LAN-30, "

EPS CONTROL UNIT
Protection Function
INFOID:0000000012431947
EPS control unit decreases the output signal to EPS mo tor while extremely using the power steering function
(e.g., full steering) consecutively for protecting EPS motor and EPS control unit (Overload protection control).
While activating overload protection control, the assist torque gradually decreases, and the steering wheel
turning force becomes heavy. The normal assist torque reactivates by no steering.

Description
• In general, customers have their own criteria for a pr oblem. Therefore, it is important to understand the
symptom and status well enough by asking the customer about his/her concerns carefully. To systemize all
the information for the diagnosis, prepare the interview sheet referring to the interview points.
• In some cases, multiple conditions that appear simultaneously may cause a DTC to be detected.

Mechanism
It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the steel belt
(the steel plates are placed conti
nuously and the belt is guided with the multilayer steel rings on both sides).
The groove width changes according to wrapping radius of steel belt and pulley from low status to overdrive
status continuously with non-step. It is controlled with the oil pressures of primary pulley and secondary pulley.
Steel belt
It is composed of multiple steel plates (A) and two steel rings (B)
stacked to a several number. The feature of this steel belt transmits
power with compression of the steel plate in contrast with transmis-
sion of power in pulling with a rubber belt. Friction force is required
with the pulley slope to transmit power from the steel plate. The force
is generated with the following mechanism:
Oil pressure applies to the secondary pulley to nip the plate. ⇒The
plate is pushed and extended outward. ⇒The steel ring shows with-
stands. ⇒Pulling force is generated on the steel ring. ⇒ The plate of
the primary pulley is nipped between the pulley. ⇒Friction force is
generated between the steel belt and the pulley.
Therefore, responsibilities are divided by the steel plate that trans-
mits the power with compression and the steel ring that main tains necessary friction force. In this way, the
tension of the steel ring is distributed on the entire su rface and stress variation is limited, resulting in good
durability.
Pulley
The primary pulley (input shaft side) and the secondary pulley (output shaft side) have the shaft with slope
(fixed cone surface), movable sheave (movable cone surface that can move in the axial direction) and oil pres-
sure chamber at the back of the movable sheave.
Pulley gear shifting operation
• Pulley gear shifting operation The movable sheave slides on the shaft to change the groove width of the pulley. Input signals of engine
load (accelerator pedal opening), engine revolution and gear ratio (vehicle speed) change the operation
pressures of the primary pulley and the secondary pulle y, and controls the pulley groove width. Along with
change of the pulley groove width, the belt contact radi us is changed. This allows continuous and stepless

Protection Control INFOID:0000000012431035
The TCM becomes the protection control status temporarily to protect the safety when the safety of TCM and
transmission is lost. It automatically returns to the normal status if the safety is secured.
The TCM has the following protection control.
CONTROL FOR WHEEL SPIN
CONTROL WHEN FLUID TEMPERATURE IS HIGH
TORQUE IS REDUCED WHEN DRIVING WITH THE REVERSE GEAR
REVERSE PROHIBIT CONTROL
DTC Inspection Priority ChartINFOID:0000000012431036
If multiple malfunction codes are detected at the same time, check each code according to the DTC check pri-
ority list below.
Control When a wheel spin is detected, the engine output and gear ratio are limited and the line pressure is increased.
At the 1GR, the clutch pressure is increased.
Vehicle behavior in
control If the accelerator is kept depressing during wheel spin, the engine revolution and vehicle speed are limited to
a certain degree. From the 1GR, upshift to a certain gear ratio is only allowed.
Normal return condi-
tion Wheel spin convergence returns the control to the normal control.
ControlWhen the CVT fluid temperature is high, the gear shift permission maximum revolution and the maximum
torque are reduced than usual to prevent increase of the oil temperature.
Vehicle behavior in
control Power performance may be lowered, compared to normal control.
Normal return condi-
tion The control returns to the normal control when CVT fluid temperature is lowered.
Control
Engine output is controlled according to a vehicle speed while reversing the vehicle.
Vehicle behavior in
control Power performance may be lowered while reversing the vehicle.
Normal return condi-
tion Torque returns to normal by positioning the selector lever in a range ot
her than “R” position.
ControlThe reverse brake is controlled to avoid becoming engaged when the selector lever is set in “R” position while
driving in forward direction at more than the specified speed.
Vehicle behavior in
control If the selector lever is put at “R” position when driving with the forward gear, the gear becomes neutral, not
reverse.
Normal return condi-
tion The control returns to normal control when the vehicle is driven at low speeds. (The reverse brake becomes
engaged.)
