*2: When the selector lever is shifted from R position to D position.
*3: If ABS system is activated, drive the vehicle at 12 km/h (7.5 MPH) or more after stop the vehicle.

CAUTION:

• The stop/start system may be cancelled when the battery is weak or if a battery other than the stop/

start system specific battery is used.

• Even though the vehicle is in above conditions, the stop/start system may be cancelled automati-

cally.
Refer to 

EC-810, "Precaution for Stop/Start System Service"

.

Stop/Start Operation Condition

When the following conditions are satisfied, ECM stops the engine. And the combination meter turns ON a
stop/start indicator lamp.

*: The condition are not used in P range.

Restart Condition

When any of the following conditions is satisfied during stop/start system operating condition, ECM restarts
the engine. And the combination meter turns OFF the stop/start indicator lamp.

SYSTEM

P Position

• STOP/START system operation performs when the selector lever is shifted from P position.

• STOP/START system operation by the brake pedal and accelerator pedal operation in the select lever P

position.

*: When the brake pedal and accelerator pedal are depressed simultaneously, the engine keeps on running.

N Position

• STOP/START system operation performs when the selector lever is shifted from N position.

• STOP/START system operation by the brake pedal and accelerator pedal operation in the select lever N

position.

*: When the brake pedal and accelerator pedal are depressed simultaneously, the engine keeps on running.

D Position

• STOP/START system operation performs when the selector lever is shifted from D position.

• STOP/START system operation by the brake pedal and accelerator pedal operation in the select lever D

position.

When driving the vehicle at Approx. 10 km/h or less after restart

When driving the vehicle at Approx. 10 km/h or more after restart

EARLY START-UP CONTROL

ECM detects engine reverse revolution based on the crankshaft position sensor (POS) when the stop/start
system is activated and judges a piston position on engine stop to reduce the time for restarting the engine.

VOLTAGE STABILIZER FUNCTION

ECM transmits a voltage stabilizer signal to the DC/DC converter during cranking at an engine restart. The
DC/DC converter temporarily increases the voltage to prevent the electric equipment from reset due to low

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:0000000010935578

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.
