GENERAL INFORMATION
FOUR-WHEEL ANTI-LOCK BRAKE SYSTEM (4ABS)35B-2
GENERAL INFORMATIONM2351000100830
The ABS that ensures directional stability and con-
trollability during hard braking. ABS is standard
equippment on the ES and GTS models but is
optional.
This ABS uses a 4-sensor system that controls all
four wheels independently of each other, and has the
following features:
•EBD *1 (Electronic Brake-force Distribution sys-
tem) control that can obtain ideal rear wheel
brake force has been employed.
•The magnetic encoder for detecting the wheel
speed has been installed instead of the rotor as
the wheel speed sensor.
•For wiring harness saving and secure data com-
munication, CAN *2 bus has been adopted as a
tool of communication with other ECUs.
NOTE: .
•*1: EBD (Electronic Brake-force Distribution)
•*2: For more information about CAN (Controller
Area Network), refer to GROUP 54C
P.54C-2.

CONSTRUCTION DESCRIPTION
FOUR-WHEEL ANTI-LOCK BRAKE SYSTEM (4ABS)35B-11
NOTE: .
•*1 This diagnostic trouble code is not set within
the vehicle speed of 20 km/h (12 mph) or less.
•*2 Turns ON when two or more wheels are faulty.
•*3 Stays ON until the vehicle speed reaches 10
km/h (6 mph) when the ignition switch is turned to
ON next time.
DIAGNOSTIC FUNCTION
ABS-ECU has the following functions for easier sys-
tem checks. The following items can be diagnosed
using scan tool.
•Diagnostic trouble code set
•Service data output
•Actuator test.
DIAGNOSTIC TROUBLE CODE SET
There are 43 diagnosis items. Since all the diagnos-
tic results are recorded in volatile memory
(EEPROM*), they are stored in the memory even
though the battery terminals are disconnected.
NOTE: .
•*EEPROM (Electrical Erasable & Programmable
ROM): Special type of memory that can be pro
-
grammed or erased electrically
•For each diagnosis item, refer to Service Manual.
.
SERVICE DATA OUTPUT
Using scan tool, the input data sent from the sensors
and switches can be read.
NOTE: For service data items, refer to Service Man-
ual.
