SYSTEM DESCRIPTION

The stop/start system enables the engine to automatically stop/restart with a simple operation and reduces
unnecessary idling during stoplight or traffic congestion to improve fuel economy, reduce exhaust gas, and
minimize noise.
ECM detects a vehicle condition, engine condition, and driver

s operation condition based on signals sent from

each unit and the sensors to comprehensively control the stop/start system.
The operation condition of the stop/start system is indicated by the stop/start indicator lamp on the combina-
tion meter and showing on the information display (dot matrix information display). (Refer to 

EC9-24, "Stop/

Start Indicator Lamp"

.) If a malfunction is detected in the stop/start system, the system control is automatically

deactivated and the malfunction is alerted to the driver by blinking the stop/start indicator lamp and showing
the status on the information display (dot matrix information display). When a driver

s operation is judged as

dangerous one during the stop/start system operation, the stop/start indicator lamp blinks at a high speed and
the status is shown on the information display (with dot matrix information display). The buzzer mounted on
the combination meter sounds simultaneously to warn the driver of the dangerous operation.
NOTE:
Starting the engine from stop/start system operation is regarded as “Restart”.

BASIC OPERATION

FUNCTION DESCRIPTION

When the stop/start system readiness conditions are satisfied while the vehicle is moving, the system is ready.
When the stop/start system operation conditions are satisfied while the vehicle is in a stop condition, the
engine is stopped.
In addition, the CVT electric oil pump is activated to supply oil pressure to the clutch and the pulley.

When the engine restart conditions are satisfied, ECM activates the engine restart relay, the engine restart
bypass control relay, and the engine restart bypass relay to restart the engine. And the DC/DC converter
boosts the voltage during cranking to protect the electrical equipment from low voltage.
After restarting the engine, the stop/start indicator lamp and the indication on the information display turn OFF.
NOTE:
• When engine restart conditions are satisfied during the electric parking brake operation, ECM performs the

engine restart after the completion of the electric parking brake operation. This may cause delay in engine
restart, compared with a usual engine restart.

• When the electric parking brake operation and engine restart occur simultaneously, the electric parking

brake activates after the completion of engine restart.

voltage. The adoption of the DC/DC converter enables a stable power supply to the electric equipment con-
nected to the DC/DC converter and permits a substantial lowering of the voltage. For the electrical equipment
connected to the DC/DC converter, see “SYSTEM DIAGRAM”.
NOTE:
The brightness of the head lamps may be changed due to the voltage reduction at an engine restart because
they are not connected to the DC/DC converter.

ENGINE RESTART BYPASS RELAY CONTROL

ECM controls the engine restart bypass control relay and activates
the engine restart bypass relay. When the restart conditions are sat-
isfied, ECM turns ON the engine restart bypass control relay instan-
taneously right after the restart and opens the engine restart bypass
relay. This allows a current to pass the inner resistance circuit right
after the starter motor is activated. When the starter motor is rotat-
ing, the voltage is directly supplied to the starter motor without being
passed through the inner resistance circuit in the engine restart
bypass relay because the engine restart bypass relay is closed. In
this way, ECM enables the battery voltage stabilization and reduces
the battery deterioration rate by decreasing the battery voltage drop
resulted from clanking at an engine restart.

ENERGY MANAGEMENT SYSTEM

ENERGY MANAGEMENT SYSTEM : System Description

INFOID:0000000010308991

DESCRIPTION

ECM transmits a target power generation voltage signal received from IPDM E/R to the generator via LIN
communication.
The generator includes a self-diagnosis function and transmits a diagnosis signal to ECM via LIN communica-
tion when detecting a malfunction. When ECM receives a diagnosis signal, ECM detects DTC and transmits a
charge warning lamp request signal to the combination meter to turn ON the charge warning lamp.

CHG-8, "ENERGY MANAGEMENT SYSTEM :

System Description"

CAN COMMUNICATION

CAN COMMUNICATION : System Description

INFOID:0000000010308992

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
Refer to 

LAN-51, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"

, about CAN com-

munication for detail.

HANDLING PRECAUTION

HANDLING PRECAUTION

Precaution for Stop/Start System

INFOID:0000000010308997

PRECAUTIONS FOR STOP/START SYSTEM OPERATION

The operation of the stop/start system needs to satisfy various conditions. For details of the conditions, refer to

EC9-39, "STOP/START SYSTEM : System Description (M/T models)"

 (M/T models), 

EC9-47, "STOP/START

SYSTEM : System Description (CVT models)"

 (CVT models).

The stop/start system may not operate under the conditions listed below:
• After restarting the engine, the vehicle is repeatedly stopped and started at a low speed due to traffic con-

gestion.

• When driving the vehicle repeatedly back and forth at a low speed due to parallel parking.
• When the intelligent key is not authenticated. (In this case, the KEY warning lamp built in the combination

meter blinks.)

• The battery is deteriorated. (High discharge rate.)
• A battery other than the stop/start system-specific battery is used.
• Ambient temperature is extremely low.

HANDLING PRECAUTIONS

• When engine restart conditions are satisfied during the electric parking brake operation, ECM performs the

engine restart after the completion of the electric parking brake operation. This may cause delay in engine
restart, compared with a usual engine restart.
For a smooth engine restart under the stop/start system operating condition, restart the engine before
releasing the parking brake.

• To use the stop/start system, the vehicle needs to recognize the status of battery. For this reason, the stop/

start system may not be activated immediately after battery change. 

• (For M/T only) When restarting the vehicle under stop/start system operating condition, continue depressing

the clutch pedal until the restart completes.
