ABS Function
AFS0018H
●
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 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 compartment. 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 Function
AFS0018I
●
Electronic Brake Distributor 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, Fail-Safe function is activated, EBD and ABS becomes inopera-
tive, 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 noise may
be heard from engine compartment. This is a normal status 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 Function
AFS0018J
ABS, EBD SYSTEM
In case of electrical problems with ABS, ABS warning lamp will turn on. In case of electrical problem with EBD,
Brake warning lamp and ABS warning lamp will turn on. Simultaneously, ABS become one of following condi-
tions of Fail-Safe function.
1.
For ABS trouble, only EBD is activated and condition of vehicle is same condition of vehicles without ABS
system.
2.
For EBD trouble, EBD and ABS become inoperative, and condition of vehicle is same as condition of vehi-
cles without ABS, EBD system.
NOTE:
In step 1 shown above, self-diagnosis when ignition switch is turned ON and when vehicle starts at initial time
is carried out. ABS self-diagnosis noise may be hard as usual.

CAN COMMUNICATION
PFP:23710
System Description
AFS00213
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 onto 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.
