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.

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.

CAN CommunicationBFS000G4
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped on a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only. Refer to LAN-49, "
CAN Sys-
tem Specification Chart" .

How to Perform Trouble Diagnosis For Quick and Accurate RepairBFS000CU
INTRODUCTION
Most important point to perform diagnosis is to understand systems (control and mechanism) in vehicle
thoroughly.
It is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptoms, and understand them fully.
Ask the customer about his/her complaints carefully. In some
cases, it will be necessary to check symptoms by driving vehicle
with the customer.
NOTE:
Customers are not professionals. Do not assume “maybe the
customer means...” or “maybe the customer mentioned this
symptoms”.
It is essential to check symptoms right from beginning in order to
repair a malfunction completely.
For an intermittent malfunction, it is important to reproduce
symptoms based on an interview with customers and past
examples. Do not perform inspection on ad hoc basis. Most
intermittent malfunctions are caused by poor contacts. In this
case, it will be effective to shake suspected harness or connec-
tors by hand. When repairs are performed without any symptom
check, no one can judge if malfunction has actually been elimi-
nated.
After diagnosis, make sure to perform “erase memory”. Refer to
BRC-17, "
ERASE MEMORY" .
For an intermittent malfunction, move harness or harness connectors by hand to check poor contacts or
false open circuit.
Always read “GI section” to confirm general precautions. Refer to GI-4, "General Precautions" .

TROUBLE DIAGNOSIS
ASKING COMPLAINTS
Complaints vary depending on the person. It is important to clar-
ify the customer's actual remarks.
Ask the customer about what symptoms are present and under
what conditions. Use the information to reproduce the symptom
while driving.
It is also important to use diagnosis sheet so as not to miss vital
information.
