Vacuum Sensor
INFOID:0000000011280565
Detects the vacuum in brake booster and transmits converted elec-
tric signal to ABS actuator and electric unit (control unit).
Parking Brake Switch
INFOID:0000000011280566
Detects the operation status of parking brake switch and transmits
converted electric signal from combination meter to ABS actuator
and electric unit (control unit).
VDC OFF Switch
INFOID:0000000011280567
• This is an integrated switch with switches for other functions.
• Non-operational status or standby status of the following functions
can be selected using VDC OFF switch. VDC OFF indicator lamp
indicates the operation status of function. (ON: Non-operational
status, OFF: Standby status):
- VDC function
- TCS function
- Active trace control function
NOTE:
ABS function, EBD function and Brake limited slip differential (BLSD)
function control operates.
• VDC OFF indicator lamp turns OFF (standby status) when the
engine is started again after it is stopped once while VDC OFF
indicator lamp is ON (non-operational status).
Hill Descent Control Switch
INFOID:0000000011280568
• The hill descent control system will help maintain vehicle speed on
steeper downhill grades. Hill descent control will provide braking
allowing the driver to concentrate on steering while reducing the
burden and accelerator operation.

System Description
INFOID:0000000011280569
• The system switches fluid pressure of each brake caliper to increase, to hold or to decrease according to
signals from control unit in ABS actuator and electric unit (control unit). This control system is applied to
VDC function, TCS function, ABS function, EBD function, brake limited slip differential (BLSD) function,
brake assist function, hill start assist function and Brake force distribution function.
• Fail-safe function is available for each function and is activated by each function when system malfunction
occurs.

communication:
• Brake fluid level switch signal
• Parking brake switch signal
Mainly receives the following signals from ABS actuator and electric unit (control unit) via CAN
communication:
• Brake warning lamp signal
• ABS warning lamp signal
• VDC warning lamp signal
• VDC OFF indicator lamp signal
Steering angle sensor
Mainly transmits the following signals to ABS actuator and electric unit (control unit) via CAN
communication:
• Steering angle sensor signal
• Steering angle sensor malfunction signal

SYSTEM
• Motor is activated. Brake fluid is pressurized by pump and is sent to secondary line through cut valve 2. At
the same time, pressurized brake fluid is supplied to front RH caliper through ABS IN valve.
When front LH wheel caliper pressure increases
• Motor is activated. Brake fluid is pressurized by pump and is sent to primary line through cut valve 1. At the
same time, pressurized brake fluid is supplied to front LH wheel caliper through ABS IN valve.
When rear RH wheel caliper pressure increases
• Motor is activated. Brake fluid is pressurized by pump and is sent to primary line through cut valve 1. At the
same time, pressurized brake fluid is supplied to rear RH wheel caliper through ABS IN valve.
When rear LH wheel caliper pressure increases
• Motor is activated. Brake fluid is pressurized by pump and is sent to secondary line through cut valve 2. At
the same time, pressurized brake fluid is supplied to rear LH wheel caliper through ABS IN valve.
When ABS operation starts (when pressure holds)
When front RH wheel caliper pressure holds
• Motor is activated. Brake fluid is pressurized by pump and is sent to secondary line through cut valve 2. At
the same time, because ABS IN valve and ABS OUT vale are closed, fluid pressure holds.
When front LH wheel caliper pressure holds
• Motor is activated. Brake fluid is pressurized by pump and is sent to primary line through cut valve 1. At the
same time, because ABS IN valve and ABS OUT vale are closed, fluid pressure holds.
