• During cornering, the brake control system limits changes in steer-
ing angle by controlling the inner ring brakes according to acceler-
ator pedal operation and allows smooth movement of the vehicle
to achieve stable cornering.

CONSULT Function
INFOID:0000000011280583
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
.
When “CRNT” is displayed on “Self Diagnostic Result”,
• The system is presently malfunctioning.
When “PAST” is displayed on “Self Diagnostic 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.
Mode
Function description
ECU identification
Parts number of ABS actuator and electric unit (control unit) can be read.
Self Diagnostic Result
“Self Diagnostic Result” and freeze frame data can be read and erased quickly.
*
Data Monitor
Input/Output data in the ABS actuator and electric unit (control unit) can be read.
ACTIVE TEST
Diagnostic Test Mode in which CONSULT drives some actuators apart from the ABS actuator and elec-
tric unit (control unit) and also shifts some parameters in a specified range.
Work support
Components can be quickly and accurately adjusted.
Re/programming, Configura-
tion
• Read and save the vehicle specification (TYPE ID).
• Write the vehicle specification (TYPE ID) when replacing ABS actuator and electric unit (control unit).
Item name
Display item
IGN counter
(0
− 39)
The number of times that ignition switch is turned ON after the DTC is detected is displayed.
• When “0” is displayed: It indicates that the system is presently malfunctioning.
• When except “0” is displayed: It indicates that system malfunction in the past is detected, but the system is pres-
ently normal.
NOTE:
Each time when ignition switch is turned OFF to ON, numerical number increases in 1
→ 2 → 3...38 → 39. When
the operation number of times exceeds 39, the number do not increase and “39” is displayed until self-diagnosis
is erased.
