• During VDC operation, it informs driver of system operation by blinking the VDC warning lamp.
• Electrical system diagnosis by CONSULT is available.
TCS FUNCTION
TCS FUNCTION : System Description
INFOID:0000000008462492
• The wheel spin of the drive wheels is detected by the ABS actuator and electric unit (control unit) using the
wheel speed signals from the four wheels, so if wheel spin occurs, the drive wheel right and left brake fluid
pressure control and engine fuel cut are conducted while the throttle valve opening is restricted to reduce the
engine torque and decrease the amount of wheel spin. In addition, the throttle opening is controlled to
achieve the optimum engine torque.
• During TCS operation, TCS informs driver of system operation by blinking the VDC warning lamp.
• Electrical system diagnosis by CONSULT is available.
ABS FUNCTION
ABS FUNCTION : System Description
INFOID:0000000008462493
• The Anti-Lock Braking System detects wheel revolution while braking, and it improves handling stability dur-
ing sudden braking by electrically preventing 4 wheel lock. Maneuverability is also improved for avoiding
obstacles.
• Electrical system diagnosis by CONSULT is available.
EBD FUNCTION
EBD FUNCTION : System Description
INFOID:0000000008462494
• Electronic Brake force Distribution detects subtle slippages between front and rear wheels during braking,
and it improves handling stability by electronically controlling brake fluid pressure which results in reduced
rear wheel slippage.
• Electrical system diagnosis by CONSULT is available.

APPLICATION ITEMS
CONSULT can display each diagnostic item using the diagnostic test modes as following.
WORK SUPPORT
SELF DIAGNOSTIC RESULT
Operation Procedure
Before performing the self-diagnosis for “ABS” with CONSULT, start the engine and drive the vehicle at 30 km/
h (19 MPH) or more for approximately 1 minute.
Display Item List
How to Erase Self-diagnosis Results
After erasing DTC memory for “ABS” with CONSULT, start the engine and drive the vehicle at 30 km/h (19
MPH) or more for approximately 1 minute as the final inspection, and make sure that the ABS warning lamp,
VDC warning lamp and brake warning lamp turn OFF.
CAUTION:
If memory cannot be erased, perform applicable diagnosis.
NOTE:
• When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp,
VDC warning lamp and brake warning lamp will not turn OFF even when the system is normal unless the
vehicle is driving at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
• Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake fluid
level switch operation (when brake fluid is insufficient).
• VDC OFF switch should not stay “ON” position.
DATA MONITOR
Display Item List
NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.
Mode
Function
Work support
This mode enables a technician to adjust some devices faster and more accurately by following the indica-
tions on CONSULT.
Self diagnostic result
Self-diagnostic results 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
CONSULT drives some actuators apart from the ABS actuator and electric unit (control unit) and also shifts
some parameters in a specified range.
ECU identification
ABS actuator and electric unit (control unit) part number can be read.
Item

• The active test cannot be started when ABS warning lamp, VDC warning lamp and brake warning
lamp is ON.
• ABS warning lamp, VDC warning lamp and brake warning lamp are ON during active test.
NOTE:
• When active test is performed while depressing the pedal, the pedal depression amount will change. This is
normal. (Only solenoid valve and ABS motor.)
• “TEST IS STOPPED” in “ABS” with CONSULT is displayed 10 seconds after operation start.

• For malfunction of ABS, only the EBD is activated and the condition of vehicle is the same condition of vehi-
cles without TCS/ABS system.
NOTE:
ABS self-diagnosis sound may be heard. That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
• For malfunction of EBD, EBD and ABS become inoperative, and the condition of vehicle is the same as the
condition of vehicles without TCS/ABS, EBD system.
VDC/TCS
If VDC/TCS/ABS system malfunction electrically, VDC warning lamp is turned on, and the condition of vehicle
is the same as the condition of vehicles without VDC/TCS control.
CAUTION:
If the Fail-Safe function is activated, then perform self-diagnosis for “ABS” with CONSULT.
