SHIPPING MODE
• Shipping mode inhibits battery power consumption duri
ng transportation or storage of the vehicle. Vehicle is
set to shipping mode before being shipped from the factory.
• When ignition switch is OFF, BCM operates shipping mode.
• BCM control function is limited in shipping mode. Re mote keyless entry function does not operate in ship-
ping mode.
• For shipping mode cancel operation, refer to BCS-125, "
Work Procedure".
NOTE:
Do not cancel shipping mode during storage of the v ehicle. Shipping mode should not be canceled until just
prior to customer delivery.
TRANSIT MODE
• BCM is in transit mode if turn signal indicators in combination meter illuminate for 1 minute when ignition
switch is turned from OFF to ON.
• In this case, cancel operation must be performed.
• For transit mode cancel operation, refer to BCS-126, "
Work Procedure".
NOTE:
Do not cancel transit mode during storage of the vehicle. Transit mode s hould not be canceled until just prior
to customer delivery.

O P
Switches the fluid pressure line to increase or hold according to signals from control unit.
ABS OUT Valve
Switches the fluid pressure line to increase, hold or decrease according to signals from control unit.
Cut Valve 1, Cut Valve 2
Shuts off the ordinary brake line from master cylinder, when VDC function and TCS function are activated.
Suction Valve 1, Suction Valve 2
Supplies the brake fluid from master cylinder to the pump, when VDC function and TCS function are activated.
Return Check Valve
Returns the brake fluid from brake caliper and wheel cyli nder to master cylinder by bypassing orifice of each
valve when brake is released.
Reservoir
Temporarily reserves the brake fluid drained from brake caliper, so that pressure efficiently decreases when
decreasing pressure of brake caliper and wheel cylinder.
Yaw rate/side/decel G sensor
Calculates the following information that affects the v ehicle, and transmits a signal to ABS actuator and elec-
tric unit (control unit) via communication lines:
• Vehicle rotation angular velocity (yaw rate signal)
• Vehicle lateral acceleration (side G signal) and longitudinal acceleration (decel G signal)
Pressure Sensor
Detects the brake fluid pressure and transmits signal to ABS actuator and electric unit (control unit).
Wheel Sensor and Sensor RotorINFOID:0000000012430829
NOTE:
• Wheel sensor of front wheel is installed on steering knuckle.
• Sensor rotor of front wheel is integrated in wheel hub assembly.
• Wheel sensor of rear wheel is installed on back plate of rear brake.
• Sensor rotor of rear wheel is installed on rear brake drum.
• Never measure resistance and voltage value using a tester because sensor is active sensor.
• Downsize and weight reduction is aimed. IC for detection portion
and magnet for sensor rotor are adopted.
• Power supply is supplied to detection portion so that magnetic field
line is read. Magnetic field that is detected is converted to current
signal.
• When sensor rotor rotates, magnetic field changes. Magnetic field
change is converted to current signals (rectangular wave) and is
transmitted to ABS actuator and electric unit (control unit). Change
of magnetic field is pr oportional to wheel speed.
Stop Lamp SwitchINFOID:0000000012430830
Detects the operation status of brake pedal and transmits converted electric signal to ABS actuator and elec-
tric unit (control unit).
Steering Angle SensorINFOID:0000000012430831
Detects the following information and transmits steering angle signal to ABS actuator and electric unit (control
unit) via CAN communication:
• Steering wheel rotation amount
• Steering wheel rotation angular velocity
• Steering wheel rotation direction
