DescriptionINFOID:0000000001404180
BCM performs the ID verification with ECM that allows the engine to start. BCM starts the communication with
ECM if ignition switch is turned ON starts the engine if the ID is OK. ECM prevents the engine from starting if
the ID is not registered.

BCM (BODY CONTROL MODULE)
REAR WIPER CONTROL
BCM detects a rear wiper stopping position according to a rear wiper auto stop signal.
When a rear wiper auto stop signal is in the condition listed below, BCM stops power supply to rear wiper after
rear wiper is activated for five seconds.
NOTE:
The above operation is repeated when operating the rear wiper switch one minute after the stop of the rear
wiper caused by Fail-safe.
TURN SIGNAL LAMP CONTROL
BCM detects the turn signal lamp circuit status from the terminal voltage.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.
LIGHT & RAIN SENSOR MALFUNCTION DETECTION FUNCTION
BCM controls the following items when LIGHT & RAIN sensor has a malfunction.
Auto Light Control
Headlamp is turned ON.

Ignition relay malfunction detection function
 IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.
 IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation
coil circuit.
 If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to
alert the user to the ignition relay malfunction when the ignition switch is turned OFF.

On-Vehicle Inspection and ServiceINFOID:0000000001282496
CHECKING CONDITION OF INSTALLATION
 Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.
 Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
 Check steering gear assembly mounting bolts and nuts for looseness. Refer to ST-12, "
Removal and Instal-
lation" .
CHECKING STEERING WHEEL PLAY
 Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on the
outer circumference.
 When the measurement value is outside the standard value, check backlash for each joint of steering col-
umn assembly and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL
 Make sure that steering gear assembly, steering column assembly and steering wheel are installed in the
correct position.
 Perform neutral position inspection after wheel alignment. Refer to SR-2, "
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"" .
 Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
 Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if steer-
ing wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Check steering wheel turning force when steering wheel has
been turned 360° from neutral position using suitable tool as
shown.
4. If steering wheel turning force is out of the specification, refer to
STC-3, "
Work Flow" .
CHECKING FRONT WHEEL TURNING ANGLE

Steering wheel play : 0 - 35 mm (0 - 1.38 in)

 Check front wheel turning angle after toe-in inspection. Place front
wheels on turning radius gauges and rear wheels on stands.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
 With the engine at idle, turn steering wheel from full left stop to full
right stop and measure the turning angles.
 Measure rack stroke if angles are outside the specified value. RHD
shown LHD similar.
 Disassemble steering gear assembly to check the cause that rack
stroke is outside of the standard.
 Steering angles are not adjustable. Check steering gear assembly,
steering column assembly and front suspension components for
wear or damage if any of the turning angles are different from the
specified value. Replace any of them, if any non-standard condi-
tion exists.

EPS SYSTEM
System DiagramINFOID:0000000001697715
System DescriptionINFOID:0000000001697714
EPS CONTROL UNIT
• EPS control unit performs an arithmetical operation on data, such as steering wheel turning force (sensor
signal) from the torque sensor, vehicle speed signal, etc. Then it generates an optimum assist torque to the
EPS motor according to the driving condition.
 EPS control unit decreases the output to EPS motor while extremely using the power steering function (e.g.,
full steering) for protecting EPS motor and EPS control unit (Protect overload status). While activating pro-
tect overload status, the assist torque gradually decreases, and the steering wheel turning force becomes
heavy. The normal assist torque reactivates by not steering.
 In case of an error in the electrical system, the fail-safe function stops output signals to the EPS motor. Then
the previous state is changed to the manual steering state.
 Self-diagnosis can be done with CONSULT-III.
EPS MOTOR
EPS motor provides the assist torque by control signal from EPS control unit.
TORQUE SENSOR
Torque sensor detects the steering torque, and transmit the signal to EPS control unit.
REDUCTION GEAR
Reduction gear increases the assist torque provided from EPS motor with worm gears, and outputs to the col-
umn shaft.
EPS WARNING LAMP
Turns ON when there is a malfunction in EPS system. It indicates that fail-safe mode is engaged and enters a
manual steering state (Control turning force steering wheel becomes heavy).
Also turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF after the engine starts
if system is normal.
