CONSULT Function

APPLICATION ITEMS

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

Mode	Function description
ECU identification	Parts number of ABS actuator and electric unit (control unit) can be read.
Self Diagnostic Result	Self-diagnostic results 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	Input/Output data in the ABS actuator and electric unit (control unit) can be read.
WORK SUPPORT	Components can be quickly and accurately adjusted.
Re/programming, Configuration	Read and save the vehicle specification (TYPE ID). Write the vehicle specification (TYPE ID) when replacing ABS actuator and electric unit (control unit).

*: 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-55, "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.

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 presently 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.

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.
When performing active test again after “TEST IS STOPPED” is displayed, select “BACK”.
ABS warning lamp, brake warning lamp and VDC warning lamp may turn ON during active test. This is not a malfunction.

ABS IN Valve and ABS OUT Valve

When “Up”, “Keep” or “Down” is selected on display screen, the following items are displayed when system is normal.

ABS IN Valve and ABS OUT Valve

*: Immediately after being selected, status is “On”. Status changes to “Off” after approx. 2 seconds.

ABS IN Valve (ACT) and ABS OUT Valve (ACT)

When “Up”, “ACT UP” or “ACT KEEP” is selected on display screen, the following items are displayed when system is normal.

ABS IN Valve (ACT) and ABS OUT Valve (ACT)

*: Immediately after being selected, status is “On”. Status changes to “Off” after approx. 10 seconds.

ABS MOTOR

When “On” or “Off” is selected on display screen, the following items are displayed when system is normal.
