GENERAL DESCRIPTION
COMPONENTS/PARTS LOCATION AND BRAKE HOSE/PIPE ROUTING
The ABS (Antilock Brake System) controls the fluid pressure applied to the Wheel cylinder of each brake from
the master cylinder so that each wheel is not locked even when hard braking is applied.
This ABS has also the following function.
While braking is applied, but before ABS control becomes effective, braking force is distributed between the front
and rear so as to prevent the rear wheels from being locked too early for better stability of the vehicle.

ANTILOCK BRAKE SYSTEM (ABS) 5E-3
The main component parts of this ABS include the following parts in addition to those of the conventional brake
system.
Wheel speed sensor which senses revolution speed of each wheel and outputs its signal.
ABS warning lamp which lights to inform abnormality when system fails to operate properly.
ABS hydraulic unit/control module assembly is incorporated ABS control module, ABS hydraulic unit (actua-
tor assembly), fail-safe relay and pump motor relay.
–ABS control module which sends operation signal to ABS hydraulic unit to control fluid pressure applied to
each wheel cylinder based on signal from each wheel speed sensor so as to prevent wheel from locking.
–ABS hydraulic unit which operates according to signal from ABS control module to control fluid pressure
applied to wheel cylinder of each 4 wheels.
–Fail-safe relay (solenoid valve) relay which supplies power to solenoid valve in ABS hydraulic unit and
pump motor relay.
–Pump motor relay which supplies power to pump motor in ABS hydraulic unit.
G sensor which detects body deceleration speed. (For 4WD model only)]
This ABS is equipped with Electronic Brake force Distribution (EBD) system that controls a fluid pressure of rear
wheels to best condition, which is the same function as that of proportioning valve, by the signal from wheel sen-
sor independently of change of load due to load capacity and so on. And if the EBD system fails to operate prop-
erly, the brake warning lamp lights to inform abnormality.

DTC C1013 (DTC 13) – SYSTEM SPECIFICATIONS DIFFERENT FROM ABS
CONTROL MODULE SPECIFICATIONS
DESCRIPTION
When abnormal signal is inputted to a no-used terminal of control module white running or wrong ABS hydraulic
unit/control module assembly is installed, this DTC will be set.
INSPECTION
1) Ignition switch OFF.
2) Check for proper connection from harness to control module.
3) If OK, substitute a known-good and correct specifications ABS hydraulic unit/control module assembly.
4) Recheck system.
DTC C1015 (DTC 15) – G SENSOR CIRCUIT
DESCRIPTION
While a vehicle is at stop or running, if the potential difference between the sensor signal terminal “E19-11” and
the sensor ground terminal “E19-13” is not within the specified voltage value, or if the signal voltage while at a
stop does not vary from that while running, this DTC is set.
Therefore, this DTC may be set when a vehicle is lifted up and its wheel(s) is turned. In such case, clear the
DTC and check again.

2. G sensor 4. ABS hydraulic unit/control module connector
NOTE:
When ABS hydraulic unit/control module assembly for 4WD vehicle is installed to 2WD vehicle, this
DTC is set. Before preforming the INSPECTION as shown below, check part number for supply of ABS
hydraulic unit/control module assembly referring to parts catalogue.
