BRAKE ASSIST FUNCTION : System Description

INFOID:0000000010329795

• When the driver brakes hard in an emergency, the stopping distance is reduced by increasing brake fluid

pressure.

• Fail-safe function is adopted. When a malfunction occurs in Brake assist function, the control is suspended

for ESP/VDC function, TCS function, Brake limited slip differential (BLSD) function, Brake assist function, hill
start assist function and Brake force distribution function. The vehicle status becomes the same as models
without ESP/VDC function, TCS function, Brake limited slip differential (BLSD) function, Brake assist func-
tion, hill start assist function and Brake force distribution function. However, ABS function and EBD function
are operated normally. Refer to

BRC-21, "Fail-Safe"

hill start assist FUNCTION

hill start assist FUNCTION : System Description

INFOID:0000000010329798

• This function maintains brake fluid pressure so that the vehicle does not move backwards even if brake

pedal is released to depress accelerator pedal to start the vehicle while it is stopped on an uphill slope by
depressing brake pedal.

• This function operates when the vehicle is in stop status on a uphill slope of slope ratio 5% or more and

selector lever is in the position other than P or N.

• hill start assist function is only for the start aid. It maintains the brake fluid pressure for approx. 2 seconds

after releasing the brake pedal, and then decreases the pressure gradually. If the vehicle can start by the
accelerator operation, the brake is released automatically and a smooth start can be performed.

• Fail-safe function is adopted. When a malfunction occurs in hill start assist function, the control is suspended

BRAKE FORCE DISTRIBUTION FUNCTION : System Description

INFOID:0000000010329799

• Brake force distribution function is controlled by ABS actuator and electric unit (control unit).
• Brake force distribution function helps provide a more stable and

secure feeling.

• During cornering, when brake operation is performed brake fluid

pressure of each wheel is controlled based on steering operation
amount by the driver and vehicle cornering status amount detected
by each sensor.

• Fail-safe function is adopted. When a malfunction occurs in Brake

force distribution function, the control is suspended for VDC func-
tion, TCS function, Brake limited slip differential (BLSD) function,
Brake assist function, hill start assist function and Brake force dis-
tribution function. The vehicle status becomes the same as models
without ESP/VDC function, TCS function, Brake limited slip differ-
ential (BLSD) function, Brake assist function, hill start assist func-
tion and Brake force distribution function. However, ABS function
and EBD function are operated normally. Refer to

BRC-21, "Fail-Safe"

NOTE:
Brake force distribution function may not always be operates in all driving conditions.

ACTIVE TRACE CONTROL FUNCTION

ACTIVE TRACE CONTROL FUNCTION : System Description

INFOID:0000000010329800

• Active trace control function controls the braking utilizing the ABS actuator and electric unit (control unit),

depending on cornering condition calculated from driver's steering input and plural sensors.

• Active trace control function is aimed to enhance traceability at corners and smooth the vehicle movement to

provide confident driving.

• When the ESP/VDC OFF switch is used to turn OFF the ESP/VDC system, the active trace control system is

also turned OFF.

• When the active trace control is operated, active trace control graphics are shown on the information display

of combination meter. These are shown only when “Chassis control” is selected on the information display.
Refer to

MWI-17, "INFORMATION DISPLAY : System Description"

• When the active trace control is not functioning properly, the master warning lamp illuminates. Warning mes-

sage “Chassis control” will also appear on information display.

NOTE:
• The active trace control may not be effective depending on the driving condition. Always driving carefully and

attentively.

• Brake pedal may vibrate and brake pedal feel may change during active trace control operation. Also opera-

tion noise may be noticeable during operation. These are not abnormal conditions.

• When the active trace control is selected OFF, some functions will be kept ON to assist driver. (For example,

avoidance condition.)

CONSULT Function

INFOID:0000000010329802

APPLICATION ITEMS

CONSULT can display each diagnostic item using the diagnostic test modes as follows.

: The following diagnosis information is erased by erasing.

• DTC

• Freeze frame data (FFD)

ECU IDENTIFICATION

ABS actuator and electric unit (control unit) part number can be read.

SELF DIAGNOSTIC RESULT

Refer to

BRC-53, "DTC Index"

When “CRNT” is displayed on self-diagnosis result,

• The system is presently malfunctioning.

When “PAST” is displayed on self-diagnosis result,

• System malfunction in the past is detected, but the system is presently normal.

Freeze frame data (FFD)

The following vehicle status is recorded when DTC is detected and is displayed on CONSULT.

ACTIVE TEST

The active test is used to determine and identify details of a malfunction, based on self-diagnosis test results
and data obtained in the DATA MONITOR. In response to instructions from CONSULT, instead of those from
ABS actuator and electric unit (control unit) on the vehicle, a drive signal is sent to the actuator to check its
operation.

CAUTION:

• Never perform ACTIVE TEST while driving the vehicle.
• Always bleed air from brake system before active test.
• Never perform active test when system is malfunctioning.
NOTE:
• When active test is performed while depressing the pedal, the pedal depressing stroke may change. This is

not a malfunction.

• “TEST IS STOPPED” is displayed approx. 10 seconds after operation start.
