APPLICATION ITEMS
CONSULT can display each diagnostic item using the diagnostic test modes as follows.
*1: The following diagnosis information is erased by erasing.
• DTC
• Freeze frame data (FFD)
*2: Although “Function Test” is selectable, do not use its.
ECU IDENTIFICATION
ABS actuator and electric unit (control unit) part number can be read.
SELF DIAGNOSTIC RESULT
.
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)
When DTC is detected, a vehicle state shown below is recorded and displayed on CONSULT.
DATA MONITOR
NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.
×: Applicable
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.
*1
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.
Function Test
*2
This mode can show results of self-diagnosis of ECU with either “OK” or “NG”. For engine, more prac-
tical tests regarding sensors/switches and/or actuators are available.
Work support
Components can be quickly and accurately adjusted.
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.

ACTIVE TEST
The active test is used to determine and identify details of a malfunction, based on self-diagnosis test result
sand 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:
• “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 and brake warning lamp may turn ON during active test. This is not a malfunction.
