System diagram ▶
Operation ▶
EEM monitors the electric loads and battery conditions and controls the voltage to improve the fuel
economy and battery charging efficiency.
EBS on “-“ terminal of battery sends the battery information (voltage, current, tem
perature and
SOC) to engine ECU with LIN communication.
Engine ECU outputs the information from EBS and regulating control signal (PWM) according to the
<008c0095008e00900095008c0047009300960088008b0047008a00960095008b0090009b009000960095009a0047009b0096004702c8007302c90047009b008c009900940090009500880093004700960095004700880093009b008c009900950088009b00

Engine ECU controls the magnetic resistance between stator coil and rotor coil by controlling the
current in rotor coil according to PWM duty value.
The alternating voltage induced to stator coil is converted to direct voltage by rectifier. And, EBS

Operation of charge warning lamp ▶
ECU checks the generating voltage from alternator and circuit conditions and sends the warning lamp ON
signal to meter cluster through CAN line.Basic control logic according to the driving conditions ▶
Engine ECU determines the engine loads according to the fuel injection volume and engine speed. It
charges the battery by increasing the generating voltage during deceleration. To improve the fuel
economy by reducing the alternator load during acceleration, engine ECU decreases the generating
voltage and consumes the battery voltage.

1. CAUTIONS WHEN WORKING ON ELECTRICAL UNITS
Disconnect the negative cable from the battery
in advance when working on electrical units. -
If a fuse is blown, replace it with a fuse which
has the correct amperage rating. If you use a
fuse with higher capacity than the
specification, the component can be
damaged or catch fire. -Do not drop or appy excessive impact to
sensors and relays. -
80℃
10 A 15 A
Make sure to turn "OFF" the ignition switch
and other lamp switches before disconnecting
or connecting the negative battery cable.
(Otherwise, semiconductor parts can be
damaged.)

(5) Horn relay
The power for the theft deterrent horn relay is supplied to the ICM terminal no. C5 through the battery
SB1 and fuse no. 45 in the interior fuse box.
The relay is operated by the signals from the BCM terminal no. A24. Refer to Conditions For Theft
Deterrent for operating conditions.
(6) Tailgate relay
The power for the tailgate relay is supplied to the ICM terminals no. C10 and no. B5 through the battery
SB1 and fuse no. 42 in the interior fuse box. The relay is operated (i.e. ON/OFF) by the operation signal
from the BCM terminal no. D6.
Deactivation condition ▶
Without SKM
The tailgate open relay is turned OFF immediately after the driver's door is locked or the vehicle
speed becomes 3 km/h or more during its activation.
With SKM
Refer to the section Tailgate of BCM for the operating conditions. -

(7) Shift lock relay
The shift lock relay is used in the models with A/T and receives power through the SB2 and fuse no. 31
in the interior fuse box with the IGN1 turned ON. If the operating conditions are met (stop lamp switch
ON), the battery power is supplied to the ICM terminal no. C1. If the gear mode conditions are met, the
relay is operated by the signals from the terminal no. 10 of the gear selector lever.
(8) Power outlet relay
The power for the power outlet relay is supplied to the ICM terminal no. B10 through the battery SB1
and fuse no. 46 in the interior fuse box. The relay is earthed through the fuse no. 47 in the interior fuse
box and then ICM terminals no. B2 and no. B12 when the ignition key is turned to ACC.

8) Key Hole Illumination
When opening the door with IGN OFF, the key hole lamp comes on.
When closing the door, the key hole lamp stays on for 10 seconds and goes off.
When turning the ignition switch to ON position during the operation of key hole illumination, it goes of
f
immediately.
When receiving the door lock signal (entering into theft deterrent mode), the lamp goes off.
The key hole illumination function has a priority over the immobilizer function.
If the communication with the immobilizer is interrupted, the lamp comes on for 11 seconds with the
interval of 0.5s ON/0.5s OFF regardless of the operating conditions of key hole lamp.
When turning the ignition switch to ON position in "Virgin" condition, the lamp comes on for 8 seconds
with the interval of 0.5s ON/0.5s OFF. 1.

Close: driver and passenger door are closed
Room lamp OFF control ▶
The room lamps stop operating when the BCM enters into the theft deterrent or sleep mode. (This is
to prevent battery discharge if the overhead room lamp and sensor room lamp switch is ON position.)
The room lamps go off automatically 10 minutes after the key is removed. After that, if the door unlock
or all door open signal is received and the key is inserted, the sleep mode is deactivated and the room
lamps operate for another 10 minutes.
The room lamps come on when the key is inserted (BCM without SKM) or the ignition switch is turned
to "ACC" or "ON" position (BCM with SKM) while the room lamps are OFF. 1.
