BRC-6
[ABS]
SYSTEM DESCRIPTION

EBD

Electronic Brake Distribution is a function that detects subtle slippages between front and rear wheels dur-
ing braking, and it improves handling stability by electronically controlling Brake Fluid Pressure which
results in reduced rear wheel slippage.

In case of electrical system break down, the fail-safe function is activated, EBD and ABS becomes inoper-
ative, and ABS warning lamp and brake warning lamp are turned on.

Electrical system diagnosis by CONSULT-II is available.

During EBD operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating sound may
be heard from engine compartment. This is a normal condition of operation check.

Stopping distance may be longer than that of vehicles without EBD when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
Fail-Safe FunctionBFS000CR
ABS, EBD SYSTEM
In case of electrical malfunctions with ABS, ABS warning lamp will turn on. In case of electrical malfunctions
with EBD, brake warning lamp and ABS warning lamp will turn on. Simultaneously, ABS become one of follow-
ing conditions of the fail-safe function.

For ABS malfunction, only EBD is activated and condition of vehicle is same condition of vehicles without
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 EBD malfunction, EBD and ABS become inoperative, and condition of vehicle is same as condition of
vehicles without ABS, EBD system.

[VDC/TCS/ABS]
SYSTEM DESCRIPTION

ABS

The Anti-Lock Brake System is a function that detects wheel revolution while braking, and it improves
handling stability during sudden braking by electrically preventing 4 wheel lock. Maneuverability is also
improved for avoiding obstacles.

If the electrical system breaks down, then the fail-safe function is activated, ABS becomes inoperative,
and ABS warning lamp turns on.

Electrical system diagnosis by CONSULT-II is available.

During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine room. This is a normal status of operation check.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
EBD

Electronic Brake Distribution is a function that detects subtle slippages between front and rear wheels dur-
ing braking, and it improves handling stability by electronically controlling Brake Fluid Pressure which
results in reduced rear wheel slippage.

In case of electrical system break down, the fail-safe function is activated, EBD and ABS becomes inoper-
ative, and ABS warning lamp and brake warning lamp are turned on.

Electrical system diagnosis by CONSULT-II is available.

During EBD operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating sound may
be heard from engine compartment. This is a normal condition of operation check.

Stopping distance may be longer than that of vehicles without EBD when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
Fail-Safe FunctionBFS000DU
VDC/TCS SYSTEM
In the event an electrical malfunction occurs in the system, the VDC OFF indicator lamp and SLIP indicator
lamp in the combination meter will light up. At the same time, the VDC/TCS control is not performed, and the
vehicle is in the same conditions as a vehicle not equipped with the VDC/TCS function. However, the ABS
control operates normally.
If a malfunction is detected in the throttle control system, the VDC/TCS control is not performed and only the
ABS control operates normally.
CAUTION:
If fail-safe mode is initiated, perform self-diagnosis for the VDC/TCS/ABS control system.
ABS, EBD SYSTEM
In the event there is a malfunction with the electrical system, the ABS warning lamp, VDC OFF indicator lamp,
and SLIP indicator lamp will turn on when it is the ABS that is malfunctioning, and the brake warning lamp,
ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp will turn on when it is the EBD that is
malfunctioning. At the same time, the VDC/TCS/ABS will become one of the following conditions by the fail-
safe function.

When the ABS malfunctions, only the EBD operates. The condition is the same as that of models with
VDC/TCS/ABS.
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.

When the EBD malfunctions, the EBD and ABS will not operate. The condition is the same as that of mod-
els without VDC/TCS/ABS and EBD.
